Installation
The base unit for the cordless voice terminal may be placed on a desk or
table top or mounted on a wall not made of metal. Instructions for each
installation follow.
BEFORE YOU BEGIN
Before you install the cordless voice terminal, there are certain considerations regarding its location and use:
The base unit must be installed at least 20 feet away from the control
●
unit for optimum range.
●
The base unit should not share the same power line or be within 6
feet of electromagnetic equipment such as electric motors, or equipment with microprocessors such as answering machines, personal
computers, and FAX machines.
●
Never operate the handset outside during an electrical storm.
If there are other people using cordless voice terminals in the area,
●
they cannot share the same channels. Follow the instructions for
“Programming Channels” to assign different channels to each voice
terminal.
iss1, cib3126-6
Page 8
If more than one cordless voice terminal is being used, do not place a
●
handset from one cordless voice terminal into the base unit of
another. If this accidentally occurs place the proper handset in its
corresponding base unit for at least 10 seconds.
●
The range of your cordless voice terminal may be reduced when
operating the handset around metal walls.
●
There is no visual indication on the handset when a call is being
bridged. If you need to ensure privacy on a line, program the
Privacy/Exclusion feature onto one of the line/feature buttons on the
handset, then activate it during the call. See “Using the Feature Buttons” for details.

Using the Feature Buttons
This section describes how you can program features on the programmable buttons on the handset.
Considerations for Programming MERLIN System Features
Voice Announcements do not work with the cordless voice terminal
●
and must be disabled. Otherwise if an intercom caller attempts to
make a voice announcement to the cordless voice terminal, he or she
hears a tone that sounds as though the voice announcement has
been accepted when in fact it has not.
The cordless voice terminal cannot be assigned to a paging group.
●
Since the cordless voice terminal does not have a speakerphone or a
●
display and cannot be used as the attendant or alternate attendant
console, it is not compatible with features requiring those conditions.
●
Since the cordless voice terminal does not have dual light buttons to
show programming status, the following features should be used with
caution:
Call Forwarding
>
Personalized Ringing
>
Ringing Options

iss1, cib3126-22
Page 24
If any of your incoming lines has the call waiting feature, program a
●
Recall button (#50) on one of the programmable buttons and press it
before you pick up a waiting call. If you press On/Off instead, you’ll
disconnect the call.
●
For MERLIN II System users, if you program an Auto Intercom button, idle line preference must be set to intercom.
PROGRAMMING MERLIN SYSTEM FEATURES
You can program the cordless voice terminal one of two ways:
●
Using the Administrator’s Console

Write “ICOM” on the label for the button reserved for intercom
>
calls (located to the left of On/Off).
Write the line number on the label of each button that is
>
reserved for outside calls.
Label the feature buttons using the abbreviations for the
>
features you’re programming on the corresponding buttons.
Refer to your MERLIN System documentation to perform the pro-
4
gramming procedures for each feature you’ve selected. See
“Considerations for Programming MERLIN System Features”
above.

PROGRAMMING SYSTEM 25 FEATURES
The cordless voice terminal must be administered as a 10-Button voice
terminal (set 304) and not as a 5-Button voice terminal (set 302) since
the 5-Button voice terminals do not support the message waiting capabil-
ity, but the cordless voice terminal does.
Considerations for Programming System 25 Features
●
Since the cordless voice terminal does not have a speakerphone or a
display, and it cannot be used as the attendant console, it is not compatible with features requiring those conditions.
●
If Send All Calls is programmed, select the single ring reminder since
there is no visual indication (unless Status is pressed) when this
feature is activated.
●
The five programmable buttons on the cordless voice terminal
corresponds to buttons 7 through 11 on a regular 10-button voice terminal. See Figure 11.
