C. Charge the Battery
C-04
The watch has a built-in rechargeable lithium polymer battery. Charge it for at least 3 hours when it is
going to be used for the first time. When the battery is empty, the charging cycle will be completed in less than 2
hours. When the battery is not empty, the charging time will be shorter.The performance of the battery with a
single charge depends upon its usage. If the GPS is not activated, it can run for approximately one year. 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 the
TIME mode. This can only serve as a rough estimation. The actual life may vary with change of the operating
conditions. If the battery level is nearly empty, GPS function 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 the other end of the USB cable into one of the PC’s USB connectors
