WARNING: The system must be installed in a secure (locked) area that

Important Safety Information

The label to the left of the voltage selector
switch shows the 115 and 230 volt
selection positions. If the incorrect voltage
for your country is set, use a small
flat-blade screwdriver to toggle the switch
up or down on each chassis.
The SuperStack 3 Call Processor works
with either 115 volt or 230 volt power, so
it has no mechanism for changing voltage.
