Power Saving
LCD Types
Power Saving causes the watch to enter a sleep state automatically and save power whenever the watch is left in the dark. The Power Saving feature of the watch is turned on at the factory. · Note that the watch may also enter the sleep state if the watch is blocked from light by your sleeve.
How the sleep state works
Display sleep state The display sleep state is triggered whenever the watch is left in the dark for about one hour between the hours of 10:00 p.m. and 6:00 a.m. · The display sleep state causes the display to go blank, except for
a flashing Power Saving indicator. The alarm and the hourly time signal continue to operate normally while the watch is in the display sleep state. · The watch will not enter the sleep state if it is in the Timer Mode or the Stopwatch Mode.
To recover from the sleep state
Move the watch to a brightly lit location or press any button. The watch will also recover from the sleep state if you angle it towards your eyes for reading (see "To illuminate the display with the auto light switch"). · It can take up to two seconds before display figures re-appear
after you place the watch in a well-lit area.
To turn Power Saving on and off
Use the procedure under "Configuring Home Time Settings" to turn Power Saving on or off.
Power Saving Indicator
Leaving the watch in a drawer or anywhere else it is dark can cause Power Saving to trigger in order to conserve battery power.
Function sleep state The function sleep state is triggered whenever the watch is left in the dark for six or seven days. The power saving indicator stops flashing and remains on the display to indicate the function sleep state. · The alarm and the hourly time signal are disabled while the watch
is in the function sleep state, and time calibration signal auto receive is not performed. · Digital timekeeping functions continue to operate normally in the function sleep state.
This watch is available with either of two different LCD types: light background with dark figures (black-on-white) or dark background with light figures (white-on-black). Note that all of the samples in this manual show the black-onwhite type LCD.

Time is adjusted according to time data.
Calibration Signal
· The Japanese calibration signal (Call Sign: JJY) is maintained by the National Institute of Information and Communications Technology (NICT). It is a long wave signal transmitted 24 hours a day from the Mt. Otakadoya transmitter (40kHz) located in Tamura-gun, Fukushima Prefecture, and from the Mt. Hagane transmitter (60kHz) located on the border between Saga Prefecture and Fukuoka Prefecture.
· The U.S. calibration signal (Call Sign: WWVB) is transmitted by the National Institute of Standards and technology from Fort Collins, Colorado.
Note that transmission of the time calibration signal may be interrupted occasionally due to maintenance, lightning, etc.
After the watch receives the Standard Time signal, it performs internal calculations to determine the current time. Because of this, there may be an error of up to one second in the displayed time.
Reception Range
This watch is designed to receive the standard time calibration signal of Japan (JJY) or of the United States (WWVB). The signal that is received depends on the current Home City setting. · For information about selecting a Home City, see "Configuring Home Time Settings". For information about city codes, see the "World Time
City Code List".

· Under optimum conditions, the calibration signal should be receivable up to 1,000 kilometers from the transmitter. Note that the wave is relatively weak at distances greater than 500km, so reception may be poor at long distances.
· Under optimum conditions, the calibration signal should be receivable up to 3,000 kilometers from the transmitter. Note that the wave is relatively weak at distances greater than 1,000km, so reception may be poor at long distances.
· Geographic contours, nearby buildings, seasonal conditions, the time of day, can even make reception impossible even when you are within range of the transmitter.
· Best reception is possible late at night.
Location
Reception is difficult and may even be impossible in the locations described below. Avoid such locations when performing signal reception. · You should think of your watch operating like a radio or TV when it
is receiving the calibration signal.
Among or near buildings
Near high-voltage lines
Inside a vehicle (automobile, train, plane, etc.)
Next to a household appliance or office equipment (TV, speaker, fax, computer, cell phone, etc.)
In a location where there is radio interference (construction site, airport, etc.)
Near mountains
If you are experiencing problems with reception, move away from the types of locations described above to a location with better reception, and try again.
https://manual-hub.com/
Receiving the Calibration Signal
There are two methods you can use to receive the time calibration signal.
Auto Receive (3 times per day) When the Home City setting is TYO or SEL, the time calibration signal is received automatically at 1:00, 2:00, and 3:00 each morning. · If both the 2:00 and 3:00 receive operations are unsuccessful, a
receive operation is performed at 4:00. If receive is still unsuccessful, it is performed again at 5:00. · If all five of the above receive operations are unsuccessful, a receive operation is performed again at midnight the following day. When the Home City is NYC, CHI, DEN, or LAX, auto receive is performed at midnight, and at 1:00 and 2:00 in the morning. · If both the 1:00 and 2:00 receive operations are unsuccessful, a receive operation is performed at 3:00. If receive is still unsuccessful, it is performed again at 4:00. · If all five of the above receive operations are unsuccessful, a receive operation is performed again at 5:00.
Manual receive (You initiate reception using a button operation.)
The watch is set up for auto receive at the factory, so all you need to do is to place it in a location that allows good reception each night.
