6. For Best Reception
This watch incorporates a radio antenna (9:00 position). To achieve the best reception, remove the watch from the wrist, point the 9:00 position of the watch towards the radio wave transmitter, place the watch in a stable place where reception is good such as near a window. Do not move the watch while it is receiving the radio wave.
For details on the direction of the transmitter, refer to the "Reception Area Guidelines" (p.132).
The reception level may change depending on the surrounding environment. Place the watch in different locations and directions while paying attention to the reception level (H, M or L) to find the most receptive location or orientation to give a reception level of H or M.
134
7. Poor Reception Areas
It may not be possible to receive radio waves under environmental conditions where reception is difficult or in areas susceptible to radio noise, such as those shown in the illustrations below.
jExtremely hot or cold locations
jNear high-tension electrical jInside vehicles, including lines, railway overhead wires cars, trains and aero planes or communication facilities
jNear TVs, refrigerators, computers, fax machines and other home electronics or office appliances
jNear cellular phones in use
jInside reinforced concrete buildings or underground
135
8. Receiving the Radio Waves
Three types of radio wave reception are possible: Automatic reception, on demand reception and recovery automatic reception. When the radio wave has been properly received, your watch will automatically adjust the time and date.
Automatic reception
L It is not necessary to operate buttons to perform automatic reception. Place the watch in a stable location near a window where the radio wave can be easily received with the 9:00 position (antenna for receiving the radio waves) pointing towards the transmitter. The watch will receive the radio waves automatically at 2 a.m. every day. If the radio wave cannot be received at 2 a.m., it will try again at 4 a.m.
On demand reception (manual reception)
L Radio waves can be received at any time. Use this function when automatic reception is impossible. 1. Remove the watch from the wrist, then press the lower right button (A) for more than 2 seconds and release it when the second hand rapidly moves and stops at the RX position.
136
2. Place the watch in a stable location near a window where the radio wave can be easily received with the 9:00 position pointing towards the transmitter. L Subsequently, the second hand will move from the RX position to the H, M, or L position during reception. L When reception is finished, the second hand will move from the H, M, or L position and return to 1-second interval movement. (This may take up to approx. 13 minutes.)
Refer to "Confirming the Reception Status" (p.139) to check the reception status.
Recovery automatic reception
If the watch stops due to insufficient charging, expose the watch to sunlight to recharge it. When the watch is recharged sufficiently, it will automatically receive the radio wave once. Regularly charge your watch so it does not become insufficiently charged.
* If the lower right button (A) is pressed for more than 1 seconds during reception, the reception will be cancelled and the hands will return to the current time.
137

Solar Power 13. Solar Power Function
This watch uses a secondary battery to store electrical energy. When the watch is fully charged, it will maintain its accuracy for about 7 months.
<Ensuring best operation of the watch>
Always store the watch in a bright location for best results.
j Placing the watch near a window where its face can receive sunlight or near another source of light when you are not wearing it will ensure that the watch is regularly charged, allowing it to maintain its accuracy.
j Wearing clothes with long sleeves makes it difficult for the watch to get the necessary light, resulting in insufficient charging. It is recommended to charge the watch by exposing to direct sunlight for a long time once a month.
[NOTE] Do not charge on surfaces that can easily become hot, such as a car dashboard.
150
151
14. Characteristics of the Solar Powered Watch
When the watch is insufficiently charged, the indication will be changed as follows:
[Normal indication]
[Insufficient charge warning]
The watch has been insufficiently charged because the watch face has not received sufficient light.
152
2-second interval
movement The second hand starts moving at 2-second intervals.
*1. When the watch stopped due to an insufficient charging It takes at least 40 minutes to recharge sufficiently to perform recovery automatic reception, even if the watch is being exposed to light. After recovery, refer to "Guide to Charging Time" and sufficiently charge the watch.
*2. If the watch failed to perform recovery automatic reception The time is incorrect even if the second hand moves at 2-second intervals, so after fully charging the watch, set the time manually or perform on demand reception.
The insufficient charge warning (a 2-second interval movement) continues for more than 2 days.
The watch will stop due to an insufficient charging.
[Recovery automatic reception]
Sufficiently charge by exposing the watch face to the light*1
When a radio wave has been successfully received*2
When the watch is recharged sufficiently, it will receive the radio wave automatically once.
153
A. Power Saving Function
When the watch face is continuously not exposed to light for 1 week or more, each hand stops at the 12:00 position and the watch enters power saving mode (to reduce power consumption).
[The following functions are available even during power saving mode] L The time is always being kept inside the watch. L The calendar will be automatically updated
(day, date).
<Cancelling the power saving function> The power saving function will be automatically cancelled when the watch face is exposed to light.
L After the power saving function has been cancelled, the hands will rapidly move to the current time and return to 1-second interval movement.
L If the watch is insufficiently charged, the second hand will begin the 2-second interval movement. Once again charge the watch sufficiently to return the second hand to normal movement.
[NOTE] The power saving function cannot be cancelled with crown or button operations. Cancel the power saving function by placing the watch in light.
154
Hands stop at the 12:00 position.
155
B. Insufficient Charge Warning Function
The second hand's movement changes from 1second intervals to 2-second intervals to show that the watch is insufficiently charged. If the face of the watch is not exposed to light for about 2 days from the beginning of 2-second movement, the hands will stop at the 0:00:00 (midnight) position.
[NOTE]
If the second hand is moving at 2-second
intervals, the time cannot be corrected
manually, or by using automatic 2-second interval
reception or on demand reception.
movement
j If the charging insufficiency occurs during "Radio wave reception", "Confirming the reception status", "Time difference correction" or "Checking/correcting the reference position", the operation will stop automatically, the watch will return to the time before the operation, and 2-second interval movement will begin. Regularly charge your watch so that it does not become insufficiently charged.
156
C. Overcharging Prevention Function
No matter how much the watch is charged, it will not affect the secondary battery, timekeeping, functions or performance of the watch. When the secondary battery becomes fully charged by exposing the watch face to light, the overcharging prevention function is automatically activated to prevent the battery from being charged further.
157
D. Guide to Charging Time
The following values are guidelines for when the watch face is being continuously exposed to the light.
Illuminance (lx)
Environment
Charging time (approximate)
For a 1-day movement charging time
Time for full charging

10,000 Cloudy sky
12 minutes
45 hours
100,000 Direct summer sunlight
5 minutes
30 hours
The table can be used to find an estimate of the amount of energy that the watch can store depending on the environment and amount of time the watch is charged. For example, you can see that the energy that can be stored when the watch is subjected to approximately 4 hours of light under cloudy skies is sufficient to operate the watch for about 20 days. 158
For a 1-day movement charging time... The charging time to run the watch for one day with normal movement.
Time for full charging........................... The time for full charging after the watch has stopped due to an insufficient charging.
[NOTE] A fully charged battery will run the watch for about 7 months without further charging. The watch will maintain its accuracy for about 2.5 years when running in the power saving mode. Charge the watch every day, as it will take a long time to recharge it, as is indicated in the table, when it stops due to an insufficient charging. It is recommended to charge the watch by exposing to direct sunlight for a long time once a month.
159
E. Handling Your Solar Powered Watch
WARNING Handling the secondary battery
j Do not remove the secondary battery from the watch yourself, unless unavoidable. f you must remove the battery, store it out of reach of children to avoid accidental ingestion. If the secondary battery is ingested, consult a doctor immediately.
j Do not throw away with regular trash. Doing so could cause a fire or environmental damage. Follow the collection procedures as specified by your local authority.
WARNING Do not use anything other than the specified secondary battery
j The watch will not operate if incorrect battery types are inserted. Never use a regular silver battery. The battery could overcharge during the charging process and burst, causing damage to the watch or injuries to the wearer.
CAUTION Charging precautions
j Do not charge the watch in a high-temperature environment (about 60°C/140°F or more). Overheating while charging can cause the watch exterior to become discolored, the watch to deform or the movement to be damaged. Example) · Charging close to incandescent lighting, halogen lamps, or other lighting sources that easily become hot. · Charging on surfaces that can easily become hot, such as a car dashboard.
j When charging with incandescent lighting, halogen lamps, or other lighting sources that easily become hot, place the watch at least 50 cm (20 in.) away from the source to avoid overheating.

Remedy
Radio wave cannot be received (where reception is possible).
L Are there objects nearby that could block radio waves or generate noise?
L Are you attempting to receive the radio wave in a location far from a window ?
L Avoid objects that block radio waves or generate noise. Try to receive radio waves by pointing the 9:00 position of the watch in the direction of the radio wave transmitter. Find a location such as window that is conducive to radio wave reception and change the watch location, direction and angle. (p.134)
L Are you moving the watch while receiving the radio wave and the second hand is indicating RX, H, M or L ?
L Do not move the watch until the radio wave has been properly received (until normal hand movement returns).
(Reception can take from about 2
minutes to a maximum of 13 minutes.)

WARNING: Water-resistance performance
· Water-resistance for daily use (to 3 atmospheres): This type of watch is water-resistant to minor exposure to water. For example, you may wear the watch while washing your face; however, do not use while swimming.
· Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch is waterresistant to moderate exposure to water. You may wear the watch while swimming; however, do not use while skin diving or scuba diving.
· Upgraded water-resistance for daily use (to 10/20 atmospheres): This type of watch may be used for skin diving; however, it is not designed for scuba or saturated diving using helium gas.
CAUTION
· Be sure to use the watch with the crown pressed in (normal position). If your watch has a screw-lock type crown, be sure that the crown is locked securely.
· Do NOT operate the crown or button when the watch is wet. Water may enter the watch and compromise water-resistance.
· The durability of a leather band may be affected when wet, owing to the properties of the material. In the case of a watch of upgraded water resistance for daily use that is frequently used in water, fading, peeling of adhesive or other problems may occur. It is therefore recommended to use another type of band (metal or rubber watchband).
· If the watch is used in seawater, rinse with fresh water afterward and wipe with a dry cloth
168
· If moisture has entered the watch, or if the inside of the crystal is fogged up and does not become clear within a day, take the watch to your nearest Citizen Service Center for repair. Leaving the watch in such a state will allow corrosion to form inside.
· If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown, buttons, etc.) may come off.
CAUTION: Keep your watch clean.
· Leaving dust and dirt deposited between the case and crown may result in difficulty in pulling the crown out. Rotate the crown while in its normal position, from time to time, to loosen dust and dirt and then brush it off.
· Dust and dirt tend to be deposited in gaps in the back of the case or band. Deposited dust and dirt may cause corrosion and soil your clothing. Clean the watch occasionally.
Cleaning the Watch · Use a soft cloth to wipe off dirt, perspiration and water from the case and crystal . · Use a soft, dry cloth to wipe off perspiration and dirt from the leather band. · To clean a metal, plastic, or rubber watchband, wash away dirt with mild soap and water.
Use a soft brush to remove dust and dirt jammed in the gaps in the metal band. If your watch is not water-resistant, take it to your dealer. NOTE: Avoid using solvents (thinner, benzine, etc.), as they may damage the finish.
169
CAUTION: Operating environment
· Use the watch within the operating-temperature range specified in the instruction manual. Using the watch where temperatures are outside the specified range, may result in deterioration of functions or even stoppage of the watch.
· Do NOT use the watch in places where it is exposed to high temperature, such as in a sauna. Doing so may result in a skin burn.
· Do NOT leave the watch in a place where it is exposed to high temperature, such as the glove compartment or dash-board of a car. Doing so may result in deterioration of the watch, such as deformation of plastic parts.
· Do NOT place the watch close to a magnet. Timekeeping will become inaccurate if you place the watch close to magnetic health equipment such as a magnetic necklace or a magnetic latch of a refrigerator door or handbag clasp or the earphone of a mobile phone. If this has occurred, move the watch away from the magnet and reset the time.
· Do NOT place the watch close to household appliances that generate static electricity. Timekeeping may become inaccurate if the watch is exposed to strong static electricity, such as is emitted from a TV screen.
· Do NOT subject the watch to a strong shock such as dropping it onto a hard floor.
170
· Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases. If solvents, such as thinner and benzine, or substances containing such solvents come in contact with the watch, discoloration, melting, cracking, etc. may result. If the watch comes in contact with mercury used in thermometers, the case, band or other parts may become discolored.
Periodical inspections Your watch needs inspection once in every two or three years for safety and long use. To keep your watch water-resistant, the packing needs to be replaced regularly. Other parts need to be inspected and replaced if necessary. Ask for Citizen genuine parts upon replacement.
