2.2. 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 12V output and 1A switching power adapter is
generally used to power CH-MG.
 In addition to the adapter, there is a rechargeable battery inside CH-MG
which serves as a back-up in case of a power failure.
 During normal operation, the AC power adapter is used to supply power to
CH-MG and at the same time recharge the battery. It takes approximately
72 hours to fully charge the battery.
 After power is supplied to CH-MG, press the power button once to power
on the Control Panel.
