1. External Power
2.1mm ID x 5.5mm OD external power jack. While this unit is designed to
operate on battery power, this input allows the unit to also be powered from a wall power outlet
by using an AC power adapter. Plug the AC power adapter itself into the wall outlet, then
connect the AC adapter’s low voltage DC output cord to this input jack. Note that power
automatically switches to external when external power is supplied, and back to battery when
external power is removed.
