This permits the system power to be switched off without switching over to battery operation.
Note
Never stop the AC power supply to the VX-2000DS as doing so causes the system power source to
be maintained by the battery.
[To restore the power supply to the system]
Step 1. Shift the Setting switch on the VX-2000DS rear panel back to the "DC" position.
Step 2. Operate the system normally.
