1. Squeeze the sides of the power connector and push the power cable connector into the
MX7 port until it clicks. The click means the connector is seated firmly.
2. The System LED above the Scan key illuminates when the MX7 is charging the main
battery pack using external power through the power cable. The backup battery is always
being trickle charged by the main battery pack..
Whenever possible, use the AC power adapter with the MX7 to conserve the main battery power
and maintain a charge in the backup battery.

The LXE-approved AC Power Adapter is only intended for use in a 25°C (77°F) maximum
ambient temperature environment.
If the AC power cable is not included with the AC Adapter, please contact your LXE
