Trouble on One Voice Terminal
TEST B: CONTROL UNIT TEST
Do this test only if the previous test indicated the trouble was not caused by the
voice terminal.
Step 1.
Go to the control unit and locate the Voice Terminals jacks for the voice
terminal on which the trouble appears and for the voice terminal with no
trouble. Switch these two cords at the control unit (see Figure 14). The
number of the Voice Terminals jacks should match the intercom
number of the voice terminals.
