TROUBLE ON AN ACCESSORY
This procedure should be used only if the trouble appears on an accessory. If there
is trouble with an accessory, see if there is an auxiliary power unit connected to the
control unit Auxiliary Power socket. Also, see if there is a voice terminal power
supply connected to a 34-button deluxe voice terminal (see Figure 38). If there is an
auxiliary power device (auxiliary power unit or voice terminal power supply), check
it first using Test A. Whether you use Test B or Test C depends upon the accessory
having trouble.
