We recommend using OEM charger to recharge the tracker. this tracker use the 5V DC voltage to
recharge, so too high voltage or AC voltage may damage the tracker or even cause accidents.
Use the car adapter or home charger or PC USB to recharge the tracker: insert the USB wire into
the charge board and car adapter or home charger or PC USB, and put the tracker on the charging
board, If the LED on the adapter is RED, it means it is recharging, if the LED on the adapter is
GREEN, it means the recharging is finished. This will take about 5-10 hours.

When the battery voltage in the tracker is too low, the tracker GREEN LED will flash 3 or 4 times, and send
battery low alarm information to authorized number, and later if the battery power is too low, it will power off
automatically.
