1.2. The Power Supply
An AC power adapter is required to
connect to a wall outlet. Be sure only to
use an adapter with the appropriate AC
voltage rating to prevent component
damage. A DC 12 V output and 500 mA
switching power is generally used to
power IC2020.
In addition to the adapter, there is a
rechargeable battery inside IC2020, which
serves as a back-up in case of a power
failure.
The battery used is a Ni-MH 600 mA and
7.2 V rechargeable battery.
During normal operation, the AC power
adapter is used to supply power to IC2020
and at the same time recharge the battery.
When the battery is fully charged, it serves
as a back-up power source for a period of
at least 30 hours. It takes approximately
48 hours to fully charge the battery.
The battery can be manually disconnected
by the battery switch located at the bottom
(covered with a rubber cap).
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.

1.3. Line Capture
IC2020 features Master Control over the
telephone line. That means, even if the
phone line is engaged, the IC2020 has
the power to circumvent the line and dial-
out anyway.
