Battery Charging
The Dual Band Receiver is fully operational while the batteries are being charged. Charging
can occur whether or not the unit is powered on. However, with the unit powered off, there
will be no way to monitor the charge cycle.
When the display shows “BATTERY LOW”, the battery has less than 10% of its maximum
capacity remaining. Connect the AC/DC adapter (9V /300mA) to the unit’s CHARGE jack.
Plug the adapter into a 115V 60 Hz power outlet. An internal battery charger will control
and terminate the charging of the 4 NiMH cells within each unit. Allow about three hours
to fully charge the batteries.
A.)
The charge cycle begins in the charge pending phase. For a period of time, the battery
display area may alternate between displaying the normal battery bar and the message
