To check the internal battery’s charge status, press the Battery Voltage and % Indicator button (the screen
will turn off in 10 seconds). Charge the internal battery if the display shows it is under 100%.

disconnected from all devices and charging sources for a few hours.
AC Charging:
1) Insert AC charging adapter into charging jack of the unit.
2) Plug the other end of AC charging adapter into a wall socket.
DC Charging in Your Vehicle:
You may also charge the internal battery while driving, using a male-to-male charger cable.

2) Insert one end of the accessory cable into the 12V DC power outlet.

be overcharged. Monitor the progress of the charge by pressing the Battery Voltage and % Indicator
button and do disconnect immediately after battery is fully charged. Completely disconnect the
charger cable when the engine is not running.
