TC56/TC57 Battery Charging
1. Ensure the cradle is connected to a power source. See Connecting Power on
page 9.
2. Insert the TC56/TC57 into the vehicle cradle. See Inserting and Removing the
TC56/TC57 on page 13.
The TC56/TC57 starts to charge through the vehicle cradle as soon as it is
inserted. This does not deplete the vehicle battery significantly. The battery
charges in approximately three hours. See LED Indicators on page 15 for all
charging indications.
The vehicle cradle operating temperature is -20°C to +50°C. When in the cradle,
the TC56/TC57 will only charge when its temperature is between 0°C to +40°C.
The TC56/TC57 always performs battery charging in a safe and intelligent
manner. At excessive high or low temperatures, the TC56/TC57 may for small
periods of time alternately enable and disable battery charging to keep the battery
at acceptable temperatures. The TC56/TC57 indicates when charging is disabled
due to abnormal temperatures via its LED and a notification appears on the
display.
