In addition to the adapter, there is a
rechargeable battery inside the
Control Panel that serves as a back
up powering source in case of any
power failure condition.
z
The battery used is a 7.2V 1600 mAH
Ni-MH rechargeable battery pack.

During normal operation, the AC
power adapter is used to supply
power to the Control Panel and at the
same time recharge the battery.

When the battery is fully charged, it
can provide back-up power for a
period of at least 10 hours
.
It takes
approximately 48 hours to fully charge
the battery.

Battery Switch is set as
ON
by factory
default. If switched to
OFF
, the battery
will not be charged when AC power is
connected, nor will it serve as a back-
up power source when AC power is
missing.

Both
Backlit LCD display

are equipped with
backlit to add the convenience of easy
operation in dark. However, when the

rechargeable battery, both Backlit
features will be disabled until the AC
power is supplied again.
