CASIO Module No. 5070

Important Information

Battery

The battery installed at the factory is discharged during shipping and storage. When you first notice signs of insufficient power (dim display), the battery must be replaced by an authorized CASIO service center or a CASIO dealer.

Water Resistance

For all categories of watches, do not:

• Press buttons underwater.
• Set hands underwater.
• Unscrew the crown underwater.

If the watch is exposed to salt water, rinse it thoroughly and dry it with a soft cloth. Do not wear a watch with a leather strap while swimming. Avoid prolonged contact of a leather strap with water.

Watches are classified by water resistance level (from I to V) according to their degree of water protection. Check your watch's level using the table below to determine its correct usage.

Notes:

• Level I watches are not water resistant. Avoid all moisture.
• II WR (Water Resistant) means the model is waterproof according to ISO 2281. Short-term contact with water will not cause problems.
• III With 5 Bar (50 meters) water resistance, the watch can withstand water pressure of the indicated value and can therefore be used during showering and short-term swimming.
• IV Water resistance of 10 Bar (100 meters) means the watch can be used during normal swimming and snorkeling.
• V Water resistance of 20 Bar (200 meters) means the watch can be used for scuba diving (except for depths requiring a helium-oxygen mixture).

Care Instructions

Never attempt to open the case or remove the back cover.

Replacement of the rubber gasket that protects the watch from water and dust should be done every 2-3 years. If moisture gets inside the watch, have it checked immediately by your nearest dealer or CASIO distributor.

Some watch bands may have silk-screened images. Be careful when cleaning these bands to avoid damaging the designs. For plastic bands, a white powdery substance may appear; this is harmless and can be wiped away. Moisture or sweat can damage plastic bands over time. Keep plastic bands clean and dry. For fluorescent cases and bands, prolonged exposure to direct sunlight or moisture can cause the fluorescent color to fade.

Watch Face and Buttons

The watch face features a digital display. Buttons are typically located on the sides of the case. Button B is used to activate the display backlight.

Operating Modes Overview

The illustration shows the general appearance of the watch in the Current Time Mode. Press button C to cycle through modes in the following sequence:

• Current Time Mode
• World Time Mode

In any mode, press button B to activate the display backlight.

Current Time Mode

In the Current Time Mode, pressing button D cycles through the display of day of the week, month/day, and hour/minute.

Setting the Time and Date

1. In Current Time Mode, press button A. The seconds display will flash.

2. Press button C to cycle through the settings in the following order: Seconds → Hour → Minute → 12/24 Hour Format → DST (Daylight Saving Time) → Year → Month → Day.

3. If seconds are flashing, press button D to reset them to 00. If seconds are between 30 and 59 when D is pressed, the minute count will increment by 1. If seconds are between 00 and 29, the minute count will not change.

4. To change minutes, hours, etc., use button D to increase the value and button B to decrease it. Holding down buttons allows for faster adjustment.

Backlight

In any mode, press button B to turn on the backlight. The backlight automatically activates when any audible signals sound. The watch uses LED panels for illumination; their power decreases after a certain period of use. A faint audible signal may be heard when the display is lit, due to LED vibration; this is not a malfunction. The backlight may be difficult to see in direct sunlight. Frequent use of the backlight shortens battery life.

Setting Backlight Duration

1. In Current Time Mode, press and hold button A until the seconds display starts flashing, indicating the start of settings.

2. Press button C nine times to advance to the backlight duration setting.

3. Press button D to switch between 1-second and 3-second backlight durations.

4. After setting, press button A.

World Time Mode

This mode allows you to view the time in any of 27 cities (29 time zones). World time is synchronized with the current time, so manual setting is not required. Press button D to view time in other cities. To enable Daylight Saving Time (DST) for a selected city, press button A.

Analog Time Mode

The analog time is synchronized with the current digital time, so it does not require separate setting. However, if the analog time does not match the digital time for any reason, follow these steps to adjust it:

1. In Analog Time Mode, press and hold button A until the digital time display starts flashing, indicating the start of settings.

2. Use button D to set the current time. Each press of button D advances the time by 20 seconds. Pressing button B while holding D allows for faster time adjustment. Press any button to stop the fast adjustment.

3. After setting, press button A.

Countdown Timer Mode

The countdown timer can be set for a duration of 1 to 60 minutes. When the countdown reaches zero, a long beep sounds. The last 10 seconds of the countdown will beep every second. With the auto-repeat mode enabled, a beep sounds when the countdown reaches zero, and the countdown immediately restarts from the preset time. This can repeat up to 8 times. You can also set audible signals during the countdown. At the start of every fifth minute and 30 seconds before the end, 4 short beeps will sound. Then, a beep will sound every second for the last 10 seconds. If the start time is 6 minutes or more, a beep will sound every second for the last 10 seconds down to the 5-minute mark. At the 5-minute mark, 4 short beeps will sound.

• Split Time: D (Start) – A (Split time, SPL indicator appears) – A (Resume) – D (Stop) – A (Reset)
• Dual Finish: D (Start) – A (Split. First finisher's result displayed) – D (Second finisher) – A (Cancel split. Second finisher's result displayed) – A (Reset)

Alarm and Hourly Chime Mode

You can set up to five different alarm sounds. When the set time is reached, the alarm will sound for 10 seconds. If the hourly chime is enabled, a short beep will sound at the start of each hour.
