THE POWER SUPPLY
VCM is powered by an AC adaptor connecting to a wall socket. Be sure to use only an adaptor with the
appropriate AC voltage rating to prevent component damage. A DC 6V output and 2A adaptor is generally
used to power the VCM.

The power adaptor is applied to the VCM at factory before shipment. User is simply required to plug
in the adaptor to wall socket.
Step 1. From under the VCM, locate the AC adaptor connected to VCM.
Step 2. Plut the AC adaptor to wall socket.
BACKUP BATTERY:
The VCM uses 1.5V x 4 alkaline batteries as its backup power source. The battery life lasts for
approximately 1 year before complete exhaustion.
<NOTE>
" The adaptor is used for daily operation, it provides power and at the same time charges the
battery. The rechargeable battery serves as a backup power source.
" The VCM can detect if the power is low. Low Battery status operates at a threshold of 5.6V.
The VCM will recognize Low Battery condition if the operating voltage <5.6V continues for 24
hours.
" In low battery status, a warning beep will be delivered every 45 secs until battery comes to
complete exhaustion.
