Power Sources

Your unit operates with the following power sources:

AC adapter/charger (connected to standard power outlet—indoor use
only). Compatible car outlet adapter available upon request.

One lithium-polymer rechargeable battery (automatically takes over if
you disconnect the unit from its external power source).

Possible to switch from an external power source to battery power
or vice versa without affecting operation.

The battery recharges automatically when the unit is connected to
an external power source (with the AC adapter/charger or car
outlet adapter).

Note: The battery will not recharge when the ambient temperature is below 5 °C

(41 °F) or above 40 °C (104 °F).

Note: When the unit is powered by battery and the battery level becomes

critically low, the unit will be shut down and unsaved data will be lost.
