1.2. The Power Supply
z 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 12V output and 1A
switching power is generally used to
power CTC-1052.
z In addition to the adapter, there is a
rechargeable battery inside CTC-1052,
which serves as a back-up in case of a
power failure.
z During normal operation, the AC power
adapter is used to supply power to CTC-
1052 and at the same time recharge the
battery. It takes approximately 72
hours to
fully charge the battery.
z The battery can be manually disconnected
by the battery switch located at the bottom
(covered with a rubber cap).
z Battery Switch is set as OFF by factory
default, 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. You need to switch
the battery to ON after supplying AC
power to CTC-1052
