9.1. What Is the CPU OFF Function?

The CPU OFF function bypasses the CPU*, which the VM-3000 system uses in ordinary broadcasts, and

allows all-zone calls to be made from the VM-3360VA or VM-3240VA or RM-300MF. Use this function when

ordinary broadcasts cannot be made due to system failures, etc.

* A signal processing unit installed in the VM-3240VA, VM-3360VA, VM-3240E, or VM-3360E and RM-300MF.

9.2. Making All-Zone Calls Using the CPU OFF Function

9.2.1. Making all-zone calls from the VM-3240VA or VM-3360VA

While the Emergency Activation switch on the front panel of the VM-

3360VA or VM-3240VA and the Emergency Microphone’s Talk key

are simultaneously held down, the Emergency indicator (red)

remains lit and the amplifier is placed in CPU OFF condition,

allowing all-zone calls to be made from the Emergency Microphone.

Adjust the sound volume with the Emergency Microphone’s volume

control.

9.2.2. Making all-zone calls from the RM-300MF using the CPU OFF function

Set DIP switch 8 on the RM-300MF’s bottom surface to the ON position to use the CPU OFF function. Setting

the RM-300MF’s front-mounted CPU ON/OFF switch to the OFF position causes the CPU OFF indicator to

light red, placing the unit in CPU OFF mode. Pressing the Emergency Microphone’s Talk key allows all-zone

calls to be made from the Emergency Microphone. Adjust the sound volume with the microphone volume

control.
