If the WeHunt GPS is not used for three minutes, it will switch to hibernation mode. Once in hibernation mode, the GPS will stop communicating with the GPS satellites in order to save battery power. The GPS will continue to communicate with the GSM network so that it can quickly send away positions again when the unit starts moving.
When in hibernation mode, the GP’s green LED light will flash to indicate that there is GSM coverage.
Communicating with the GSM network uses a certain amount of power, so the unit’s battery will be drained after a few days.
Movement such as floor vibrations or transportation of the GPS may ‘wake up’ the GPS from hibernation mode; this will increase consumption of the battery power and may shorten the battery life.
Meaning of different green lights
Slow and long flashes = looking for GSM network
Blinks once every three seconds = connected to GSM network
Blinks twice every three seconds = connected to GPRS network
Remains constantly lit = no or invalid SIM card
Meaning of different BLUE lights
Slow and long flashes = looking for GPS signal
Blinks once every three seconds = the device has a GPS signal
Remains constantly lit (not flashing) = charging in progress
Not lit = battery fully charged (if the USB cable is connected)

If the light does not illuminate despite the unit being charged, try the following solution.
