3 Dial the intercom number for the voice terminal where the other person is

waiting for the call.

Through the speaker or your handset you’ll hear the other voice terminal ring.

At the other voice terminal, one long beep sounds, the red light glows steadily next to the fifth button down (Intercom) in the leftmost row of buttons, and the green light next to the red light flashes.

4 When the other person answers, speak into your speaker or handset to verify two-way communication.

At the other voice terminal, the green light stops flashing and glows steadily.

5 After verifying two-way communication, touch Speakerphone or hang up the handset at both voice terminals.

On both voice terminals, the lights go out, and the red light goes on next to the fourth button down in the leftmost row of buttons.

TEST EACH LINE NUMBER Go to the voice terminal for intercom 10. From any other voice terminal in

your system, have another person dial your outside telephone line numbers in order as follows:

1 Using a line other than the one to be dialed, have the other person dial

the number for line A.

When your voice terminal starts to ring, the green light flashes and the red light goes on next to the button for line A (the fourth button down in the leftmost row.)

If the green light flashes next to the wrong line button, make sure the connections are correct between the jacks in the line module(s) in the control unit and the jacks at the network interface or in the jack field. (For example, you may have plugged the line cord for line A into the wrong jack on the control unit.)

 

2 When you have verified two-way communication, touch Speakerphone or

 

 

hang up the handsets at both voice terminals.

 

3 Repeat the above steps for line B, line C, and so forth until you have

 

 

tested all of your telephone numbers.

 

Once all tests are completed successfully, replace both control unit covers.

SPEAKERPHONE

For optimal use of the speakerphone on the BIS, HFAI, or SP voice terminals,

PERFORMANCE TIPS

follow these guidelines:

 

Place the voice terminal in an area with low background noise.

 

Room acoustics and background noise may affect the proper operation of

 

 

your voice terminal’s speakerphone. High background noise is caused by

 

 

loud voices and loud office equipment such as typewriters, copiers, etc.

 

Keep books and papers away from the area under and next to the

 

 

microphone.

 

Let one person talk at a time. When both parties speak simultaneously,

 

 

transmission can be broken.

 

Always face your terminal when talking.

Place your voice terminal at least six inches away from the edge of the desk or table upon which it rests.
