Charging your watch
CAUTION
• If the surrounding temperature falls below 0°C (32°F) or exceeds 40°C (104°F),
the “
Charge suspension temperature detection function
” will activate and
charging will not be possible.
• Do not charge the watch at a high temperature (about 60°C (140°F) or higher)
as doing so may cause movement malfunction.
• If the watch is obscured from light by long sleeves frequently, supplemental
charging may be needed to ensure continual operation.
• The watch stops charging automatically after finishing (overcharging prevention
function). The function prevents damage to performance of the watch and
rechargeable cell due to overcharging.
