when engaging in other such outdoor activities.
Keep the watch exposed to bright light

• The watch continues to operate, even when it is not exposed to light.
Leaving the watch in the dark can cause the battery to run down, which will
cause some watch functions to be disabled. If the battery goes dead, you
will have to re-configure watch settings after recharging. To ensure normal
watch operation, be sure to keep it exposed to light as much as possible.

• Frequent display illumination can run down the battery quickly and require
charging. The following guidelines give an idea of the charging time
required to recover from a single illumination operation.
Approximately five minutes exposure to bright sunlight coming in through
a window
Approximately 50 minutes exposure to indoor fluorescent lighting

Operation Guide 3071 ( B )
The electricity generated by the solar cell of the
watch is stored by a built-in battery. Leaving or
using the watch where it is not exposed to light
causes the battery to run down. Make sure the
watch is exposed to light as much as possible.
• When you are not wearing the watch on your
wrist, position the face so it is pointed at a
source of bright light.
• You should try to keep the watch outside of
your sleeve as much as possible. Charging is
reduced significantly if the face is covered only
partially.

Questions and answers
What can I do if the battery dead
If the battery in a Casio 3071 watch is dead, you should expose the watch to bright light to recharge the built-in solar battery. If the battery has dropped to Level 5, all settings, including the Home City, will reset to factory defaults. After recharging, you may need to reconfigure the settings. If the battery was replaced, you must also reset the Home City and other preferences. To prevent power loss, store the watch in a well-lit area and enable the Power Saving function.

The battery doesn't work, once it turns off, the time goes back to 12
The Casio watch with part number 3071 resets to 12:00 when turned off due to a low or dead battery. To fix this issue:
1. Recharge the Battery: Ensure the watch is exposed to bright light to recharge the battery. Keeping it in the dark for long periods can cause the battery to drain, leading to function loss.
2. Check the Battery Power Indicator: If the battery power level is at Level 5, all functions are disabled, and memory is deleted. Recharge the battery until the power indicator improves.
3. Enable Power Saving: Turn on the Power Saving function and store the watch in a well-lit area to prevent battery drain.
4. Replace the Battery if Necessary: If the battery no longer holds a charge, it may need replacement. When replacing the battery, the Home City setting will reset to Tokyo (TYO), so you will need to adjust it afterward.
If the issue persists, take the watch to an authorized CASIO service center.
