from the 8-ohm output of the

music source to the “M1” and

“M2” terminals on the car-

tridge.

Warning:

Uplug the power cords of

the control unit and the

music source from the ac

outlet before making any

connections to the car-

tridge.

Wrap the end of one wire around the

8-ohm output terminal screw on your

music source. Take the same end of

the second wire and wrap it around

the other terminal screw associated

with the 8-ohm output. Tighten the

screws.

Note 1:

Note 2:

The music source should be

tested with speakers before

making the connections to

the music on hold. The ac

power should be discon-

nected from the music

source before making any

connections.

The same 8-ohm output can-

not be connected to a

speaker and the music-on-

hold cartridge. Since the

amplitude required to drive

a speaker is much greater

than the music on hold will

accept, it causes the music

on hold to be distorted.

Loosen but do not remove the two

terminal screws marked M1 and M2.

Take each wire from the output of the

music source and loop it clockwise

around a terminal screw (Figure 4).

Again, it is not critical which wire goes

to “M1” and which goes to “M2”.

Tighten the screws.

Connecting Your Paging

Note:

This section explains a typical

installation of a paging unit.

Consult your vendor’s instruc-

tions for your particular paging

unit and the description of the

cartridge to determine how to

install your paging system to

best suit your needs.

Warning:

Be sure your control unit

is unplugged from the ac

outlet before making any

connections.

Loosen the terminal screws marked

“T” and “R” on the cartridge.

Strip the ends of a pair of 24-gauge

wires and wrap them clockwise

around each of the terminal screws

and tighten.

Attach the other ends of the wires to

the 600-ohm input attachment on

your paging unit. This input may be la-

beled “telephone input”.

Note:

If your paging unit does not

have a 600-ohm input, you will

need to attach a “high impe-

dance to 600-ohm” impe-

dance matching device.

Set the slide switch labeled “Paging

Signal” on the cartridge to ON or OFF

to turn the paging prealert tone on or

off, as desired.

Installations Requiring Switched

Contact Closures

Some paging units require a switched con-

tact closure to operate correctly. Consult

your paging unit vendor’s instructions for

your system to determine if your system

require this.

If it does, follow the steps below to connect

the land 2 terminals on the cartridge to

the switched contact closure connection on

your paging unit.

Note:

The Federal Communications

Commission requires that sig-

nals be limited in loudness. If

your music on hold sounds

distorted, it may be too loud.

Turn the volume down on your

music source. If this does not

correct the problem, call the

HELP number listed in the Us-

er’s Guide or Service Manual.

Adjust the background music volume

by turning the screw above the

“Background Music” on the cartridge.

Note: To eliminate background mu-

sic, turn the screw counter-

clockwise as far as it will go.

Call the paging system from one of

the voice terminals by pressing “Inter-

com”, dialing “6”, and speaking into

the handset.

Adjust the volume of the paging unit

by using the controls on your paging

unit and speakers.

Note:

If your paging unit controls the

volume of your music source,

you may have to adjust the

volume to a suitable loudness.

Arrange the wires neatly.

Close the control unit door.

Loosen the crews marked “1” and

“2” on the cartride.

Instructions For

151A Music-on-Hold/

Wrap a 24 guage wire around each of

Paging Cartridge

the terminals.

(Type II) (6102)

Attach the other end of each wire to

the switched contact closure connec-

tion on your paging unit.

Plug the control unit power cord into

a 117-volt ac electrical outlet not con-

trolled by a switch.

Plug the music source into a 117-volt

ac electrical outlet; turn it on and set

the volume control.

Within your system, call from one line

to another and have someone answer

the called line.

Place the call on hold. The held party

should now hear the music.

With a screwdriver, adjust the music

volume to a desired level by slowly

turning the screw above the “Music-

on-Hold” designation on the cartridge.
