C. Charge the Battery
C-04
The watch has built-in a rechargeable lithium polymer battery. Charge it for at least 3 hours if it is going to be used
for the first time. If the battery is empty, the charging cycle will be completed in less than 2 hours. If the battery is
not empty, the charging time will be shorter. A quick 15-minute charging may keep GPS running for around 1.5
hours. The Battery of a single charge depends upon its usage. If the GPS is not activated, it can run for around a
year. If the GPS is ON, the battery is expected to run for approximately 8.5 hours. This rechargeable battery is
good for at least 500 charging cycles. Battery gauge function is provided. The approximate remaining time left,
when working with GPS, is calculated by pushing the [V] button once in TIME mode. This only serves as a rough
estimation. The actual life may vary as the operating conditions change. If the battery level is nearly empty, GPS
and Heart Rate Monitor functions will be disabled automatically. At this stage, the watch can still run for another 2
weeks with normal time keeping functions.
To charge the battery:
1) Align the clip guide and pins with the notch and contacts at the bottom of the watch
2) Make sure the clip is secured
3) Plug USB cable into any of the PC’s USB connectors
