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.
