Bluetooth is unable to connect
A) Check if the GPS Bluetooth indicator is flashing normally. That is, flash one per each three
second means the product is under standby mode; flash once per second means Bluetooth
has been online already.
B) Check if energy level is sufficient. If red LED is lid up, then the battery level is insufficient,
please recharge it until the red indicator is off (recharge is complete).
GPS cannot be positioned
A) Check if GPS indicator operates normally or not. If the indicator is constantly lid up, it means
that GPS is in operation; if the indicator is flashing, it means GPS is positioned already.
B) If GPS cannot be positioned for long, apply GPS info software to make a Cold Start first, and
then move to an open space performing the positioning task.
C) Check if power level is sufficient. If the red LED lights up, it means the power is insufficient,
please recharge it until the red indicator is off (recharge is complete).
