Comdial strives to design the features in our communications systems to

be fully interactive with one another. However, this is not always possible,

as the combinations of accessories and features are too varied and extensive

to insure total feature compatibility. Accordingly, some features identified

in this publication will not operate if some other feature is activated.

Comdial disclaims all liability relating to feature non-compatibility or

associated in any way with problems which may be encountered by

incompatible features. Notwithstanding anything contained in this

publication to the contrary, Comdial makes no representation herein as to

the compatibility of features.

1.2 Overview

This user’s guide covers five different telephone models. There are

several differences as noted below.

•The 8112N and 8212N do not have speakerphone capability.

Therefore, you must lift the handset to perform any telephone

functions: making calls, answering calls, programming your

telephone, etc.

•The 8112N and 8212N cannot receive voice announce calls.

•The 8112N and 8212N cannot use the Group Listen feature.

•The 8112N and 8212N cannot use the Background Music feature.

•The 8112N does not have any LEDs beside its programmable

buttons and therefore does not provide any status indications for

these buttons.

•The 8112N does not have a mute key.

•The 8112N and 8212N does not have a handset volume control.

•The IMIST device only works with the 8212S and 8212N telephones.

•The 8124S and 8112S telephones have a rocker switch style volume

control instead of separate volume up and volume down buttons.

•Message waiting lights:

–On the 8124S and 8112S, the message waiting light is above the

HOLD button.

–On the 8112N, the message waiting light is above the dialpad.

–On the 8212S and 8212N there is a dedicated message button with

an associated light beside it.

•Only the 8212S and 8212N support the ICVOL handset with

independent volume control.

•8212S and 8212N have adjustable pedestals.

1.3 Using Your Speakerphone

On the speakerphone-equipped models (8124S-**, 8112S-**, and

8212S-**) the microphone and loudspeaker are farther away from you

than when you use a handset. Both the signal from the loudspeaker and

the signal to the microphone must be strengthened. When microphones

and loudspeakers are close together (such as in a speakerphone),

additional amplification typically generates a ringing sound (public

address systems do this if the volume is too high or the microphone is

too close to a loudspeaker).

Your speakerphone’s sound-activated switches allow either the

microphone or the loudspeaker to be on at a given time. This means that

sounds travel in only one direction at a particular moment.

•To manually place a call using your speakerphone,

1. Press the line button or the INTERCOM button.

2. Dial the number.

3. When party answers, speak toward the telephone.

•To autodial using your speakerphone,

1. Press the programmed button and talk when your party

answers.

•To answer a call with your speakerphone,

1. Press the line button with flashing red or orange light.

2. Speak toward the telephone to answer the call.

•To answer an intercom call with your speakerphone,

1. Press the INTERCOM button and speak toward the telephone

after hearing two short rings,

—OR—

If your system is configured for voice-first calling, speak to-

ward the telephone to answer the call after hearing the caller’s

voice.

•To end a call with your speakerphone,

1. Press SPEAKER.

1 – 4 Non-LCD Station User's Guide

Speakerphone User Guidelines

•Both parties cannot talk at the same time. You must wait for

silence out of your loudspeaker before talking. You must stop

talking to hear the other party.

•Background noise may prevent the sound-activated switches from

operating properly. Avoid placing the speakerphone where it will

detect sounds from typewriters, keyboards, printers, paging

systems, and other equipment.

•Speak slightly louder than normal and with a clear, authoritative

voice. For the microphone to best detect your voice, speak within

three feet of it and face the telephone.

•Raising the volume of the loudspeaker makes it easier for the

sound-activated switches in your telephone to select the distant

party’s voice. Lowering the volume of the loudspeaker makes it

easier for the switches to select your voice.

•Since the system takes several seconds to provide the best

switching, constant sound patterns—such as elongating your

words and playing externally-supplied music—may prevent the

sound-activated switches from operating properly.

•Place the telephone on a hard surface and away from table edges.

Do not place the telephone in corners or enclosures. Do not let

obstructions come between you and the microphone. Rooms with

hard, flat surfaces that reflect sound may affect the

sound-activated switches.

•If you are using a handset and the other party is using a

speakerphone, avoid breathing heavily into your microphone.

Avoid other sounds that may affect the distant telephone’s

sound-activated switches.

•In some situations, such as when either you or the distant party

are in a noisy environment, you may have to lift your handset to

ensure a clear conversation.

•When both you and the distant party use speakerphones, the

sound-activated switches can occasionally detect both voices

simultaneously, thus blocking out both voices.
