Hold the ON/OFF key and the RESET key together for at least 5 seconds and then release these two keys simultaneously.
Any exchanging of the main battery should be finished within 20 minutes. Otherwise the backup battery may fail to support features such as the system clock, which may lead to power-on failure.
Attention: The cold boot operation will lead to the loss of system clock settings. If the fault doesn’t disappear after cold boot, choose "Restore factory settings".
Note: The steps of "Restore factory settings": Press the RECORD key and the roller’s Down key simultaneously, and then click the RESET key with the touchpen. In the middle of the screen displayed, choose OK item continuously with the Roller key, and then press the Roller Confirm key.
