CONNECT EACH VOICE Since the voice terminal module can be damaged if a modular cord is
TERMINAL TO THE unplugged while there is power to the control unit, make sure that the
SYSTEM control unit power is off before connecting each voice terminal to the system.
This prevents you from damaging the voice terminal module if you
accidentally pull on a cord that is attached to it. When the power is off,
follow these steps to connect each voice terminal to the system:

Place the voice terminal in its designated location.
Plug the voice terminal into the wall jack or control unit jack as indicated
on the System Configuration Form.
Go on to "Testing Each Voice Terminal."
TESTING EACH VOICE
TERMINAL When you have completed the voice terminal connections, you are ready to
test that they are connected properly.
Preparing For Testing
Make sure that the Test/Program (T/P) switch on the left side of each voice
terminal is set to the center position. This step prevents the phones from
ringing when the power at the control unit is turned on. Also, make sure the
volume control for ringing and button clicks located on the left side of each
voice terminal is in the center position.
If you’re using a BIS, SP, or HFAI model voice terminal, adjust the
speakerphone volume according to the model you have:
For 10-Button models, the speakerphone volume switch is located on the right
side of the voice terminal (Figure 19).
1 Slide the switch away from you to increase the volume.
2 Slide the switch towards you to decrease the volume.
On 22- and 34-Button models, the speakerphone volume is adjusted by a
thumbwheel located on the face of the voice terminal (Figure 19).
1 Turn the thumbwheel to the right to increase the volume.
2 Turn the thumbwheel to the left to decrease the volume.
Testing the Voice Terminals
When you have prepared each voice terminal for testing, test them as follows:
1
2
Turn on the power at the control unit.
A red light goes on next to a line button when you plug a voice terminal into it.
Test to see that each voice terminal operates properly by sliding the T/P
switch to T and, if necessary, holding it there. See Figure 20.
All the red and green lights on the voice terminal begin to flash, and a tone sounds.
