(150A) MUSIC-ON-HOLD CARTRIDGE TYPE II (6101)
This cartridge (Figure 1) is intended for use
with Models 206, 410, and 820 of the com-
munications system. When properly con-
nected to a user-provided 2-watt, 8-ohm
music source, it provides music to outside
callers who are placed on HOLD.

Music Terminals

The “M1” and “M2” terminals, when prop-
erly connected to a music source, provide
music on hold. They are a dry balanced 8-
ohm input; therefore, it is not critical which
terminal on the music source is connected
to “M1” and which is connected to “M2”
(dc offset voltage is assumed to be 0
volts). A maximum of 0.3 volts peak to
peak can be provided before the signal is
distorted. Protection is provided for larger
signals.
Music-on-Hold Volume Control
This terminal is used to adjust the volume
of your music on hold. Turning the screw
clockwise increases the volume and turning
it counterclockwise decreases the volume.
INSTALLATION INSTRUCTIONS
Warning:
Unplug the control unit
from the ac outlet and
make sure the control unit
green light goes OFF be-
fore inserting or removing
the cartridge.

Installing the Cartridge
1.
2.
Open the control unit door.
Grasp the plastic cover plate in the
middle right section of the control
unit panel marked Cartridge Type II
and pull to remove it as shown in Fig-
ure 2.
Figure 2
Slide the cartridge into the control
unit cartridge slot marked Cartridge
Type II as shown in Figure 3.

Push the cartridge slowly and steadily
until the ridge on the front of the car-
tridge is aligned with the front panel
of the control unit.
Connecting Your Music Source
Note:
This section explains how to
connect your music source to
the 150A Cartridge by running
either 18- or 24-gauge wire
from the 8-ohm input of the
music source to the “M1” and
“M2” terminals on the car-
tridge.
Warning:
Unplug 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 an
8-ohm output terminal screw on your
music source. Take the same end of a
second wire and wrap it around the
other terminal screw associated with
the 8-ohm output on your music
source. 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 input
will accept, it causes the
music on hold to be dis-
torted.
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”.
