Trouble on One Voice Terminal
TROUBLE ON ONE VOICE TERMINAL
Use this procedure only if the same trouble does not appear on the second voice ter-
minal that you have checked.
This procedure will help you find the cause of trouble that occurs on only one voice
terminal. The trouble could be caused by the voice terminal, its handset, its handset
cord, a voice terminal accessory, the expansion module, the control unit, or the wir-
ing between the control unit and voice terminal. Ways for testing each component
that might be causing the trouble are presented in this procedure.
TEST A: VOICE TERMINAL TEST
Step 1.
Step 2.
Step 3.
Make certain you have the note describing the trouble and its location.
This note is especially important for remembering the outcome of tests
during troubleshooting.
Disconnect any accessory from the
OTHER
jack of your 10- or 34-button
voice terminal. If the trouble is cleared, go to “TROUBLE ON AN
ACCESSORY.” If the trouble persists, leave the accessory unplugged and
continue.
Switch the voice terminal on which the trouble appears with the second
voice terminal that you checked (see Figure 10). The intercom number of
the working voice terminal should be five greater or five less than that of
the voice terminal with trouble. (This is done to make sure your voice ter-
minals are connected to different expansion modules.)
