Adding A Music Source(S) - Comdial DX-80 Installation & Maintenance Manual

3. Connect grounded wrist strap to a suitable earth ground. (If a
grounded wrist strap is not available, bleed any static charge
from your body before touching circuit modules by touching
the gold-painted surface of the inside of the KSU cabinet. If the
KSU is properly grounded this will momentarily discharge
static electricity from your body. NOTE: A GROUNDED
WRIST STRAP IS THE BEST METHOD OF ASSURING
THAT STATIC ELECTRICITY DOES NOT DAMAGE CIRCUIT
MODULES.)
4. Locate the long cable attached to the 408E of KSU2 and route
it out of the KSU cabinet into the KSU1 cabinet for connection
on the CPM.
5. Locate the CPM at the right-hand side of KSU1 above the
408M (and COM4 if installed).
6. Position the KSU2 connection cable over the CPM-"2
Cabinet Connector" as illustrated in the diagram above.
7. Press firmly (but not forcefully) on the KSU2-Cable connector
to secure a good connection into the CPM-"2
Connector.
8. Replace the KSU cover and secure with cover screws.
9. Restore KSU power by powering both KSU cabinets at the
same time. (Operate both cabinet power switches to the "ON"
position simultaneously.

Adding a Music Source(s)

Two sources of music can be connected to the CPM of the DX-80
system for use with the features: Music On Hold and Background
Music. (Optionally, an internal musical tune or tone can be used for
callers on hold. When this option is used, the MC1 connector is not
used.)
To select the internal music tune for use on music channel
MC1:
1. Remove the KSU cover (four screws at each corner) of
KSU1.
2. Connect grounded wrist strap to a suitable earth ground. (If
a grounded wrist strap is not available, bleed any static charge from your body before touching circuit
modules by touching the gold-painted surface of the inside of the KSU cabinet. If the KSU is properly
grounded this will momentarily discharge static electricity from your body. NOTE: A GROUNDED WRIST
STRAP IS THE BEST METHOD OF ASSURING THAT STATIC ELECTRICITY DOES NOT DAMAGE
CIRCUIT MODULES.)
3. Locate the CPM and "MUSIC" option strap.
4. Move the "MUSIC" option strap (JP30) from the "EXT" (factory position) to the "INT" position.
To install an external music source to either MC1 or MC2 or both:
1. Remove the KSU cover (four screws at each corner) of KSU1.
2. Connect grounded wrist strap to a suitable earth ground. (If a grounded wrist strap is not available, bleed
any static charge from your body before touching circuit modules by touching the gold-painted surface of the
inside of the KSU cabinet. If the KSU is properly grounded this will momentarily discharge static electricity
from your body. NOTE: A GROUNDED WRIST STRAP IS THE BEST METHOD OF ASSURING THAT
STATIC ELECTRICITY DOES NOT DAMAGE CIRCUIT MODULES.)
3. Locate the CPM and the "MUSIC" option strap.
4. Make sure that the "MUSIC" option strap is in the "EXT" position. (Required for external source to operate on
MC1.)
