Battery Charging
Ensure the cradle is connected to a power source.
Insert the TC75 into the cradle. The TC75 starts to charge through the cradle as soon as it is inserted. This does
not deplete the vehicle battery significantly. The battery charges in approximately four hours.
NOTE The Vehicle Cradle operating temperature is -40 °C to +85 °C. When in the cradle, the TC75 will only
charge when its temperature is between 0 °C to +40 °C.
