Assembly and Installation

The Unity Two-Line is a Two line electronic telephone designed
and factory wired for use with PBX,

CENTREX

or CENTRAL
OFFICE (CO) switching system. No wiring changes are required.
Follow these simple installation steps and start using your new
Unity telephone set.

CAUTION

Connections

Before installing the Unity Two-Line, ensure that the
RJ14 (two line) wall jack designated for it is properly

wired for this type of telephone. Plugging the Unity
Two-Line into a jack wired for proprietary-type tele­phones such as the Meridian

SL-1

or Meridian SL-100

terminals may damage your phone.

The Unity Two-Line is a powerful telephone with many features
such as automatic dialing and a built-in speaker for call monitor­ing. Therefore, your telephone is equipped with a transformer for
the power needed to enable these additional features.

To

prevent
accidentally turning off power to your phone, we recommend
using an outlet that is not controlled by a light switch.

Note: Make all cord connections before plugging the power trans-

former into an AC outlet.

Insert the adapter into the RJ14 (Two line) wall jack as shown
in Figure 5. Once again, a “click’ indicates that it is properly

locked into position.

Plug your transformer into an AC outlet that is within five feet

of the wall jack. (Figure 6.)

Note: During an AC power failure, you can still use the Unity
Two-Line like a standard telephone, but only on Line 1. You can
dial out manually (in tone mode) and receive incoming calls. Set
reverts to factory default setting.

quite useful. Should you have to put a line on hold to leave your
desk for some reason, you can use any phone that shares your

line

to take that line off hold and retrieve the call.

/ 2

Your Unity Two-Line comes from the factory preprogrammed to
automatically select Line 1 when you pick up the handset.
However, you also have the option of selecting Line 2 as your
Prime Line or you can program your phone so that neither is
prime.

Prime Line Select offers you several advantages, especially in an
environment where you share your lines with someone else.
Designating a Prime Line gives you a dial tone for your own line
whenever you pick up the handset to make a call. When both
lines ring at once, your telephone automatically selects your owr
line when you answer.

If you have altered the original factory setting and want to repro
gram your Unity Two-Line to designate Line 1 as prime:

-

Press the

-

Press the

[I

key.

-

Press the

key again.

Note: Prime is set to Line 1 when you reprogram for Default

To designate Line 2 as your Prime Line, substitute Line 2 for

Line 1 in the procedures above.

your two lines ring.

You automatically answer the Prime Line when you

If you have not designated a Prime Line...

You automatically answer whichever line is ringing, thus the term

Warranty

Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any
repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications com-

pany cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical

ground connections of the power utility, telephone lines and inter­nal metallic water pipe system, if present, are connected together.
This precaution may be particularly important in rural areas.

Users should not attempt to make such connection

ti

themselves but should contact the appropnate

electrrc

inspection authority, or electrician, as appropriate.

Load Number

The load number of this telephone is 27A. Load numbers are a
new concept designed to help you determine how many tele­phones can be connected to any one telephone line.

The total of the load number for all the telephones connected to
any one line should not exceed 100.

UNITY Two-Line Business Terminal. User Guide - Issue 1

40 I Warranty

An alphabetic suffix is also specified to indicate the appropriate
ringer type (A or B).

Since load numbers are new, you may not know what the load
numbers are for your previous telephones. It is usually safe to
assume that the load numbers for those telephones will be
about

20.

This means the there should be no problems with up to five

(5)

telephones on one line.
If the maximum total load number of

100 is exceeded, the tele-

phone on that line may not ring or may ring poorly. In addition,
you may not be connected to the calling party when you pick up
the receiver or may have dialing problems.

If you experience the above problems after the addition of a

tele­phone to your line, you may have exceeded the maximum total
load number of

100. In this case, you will have to disconnect on

of the telephones to reduce your total load number below

100.
