When the system power (DC) needs to be switched off in such cases as maintenance or unit configuration
change, shift the Setting switch on the VX-2000DS to the "AC" position following the procedure below.
7. SWITCHING OFF SYSTEM POWER (DC)
Step 1.
Terminate all current broadcasts to stop system operation.
Step 2.
Shift the Setting switch on the VX-2000DS rear panel to the "AC" position.
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.
