SPEAKER INSTALLATION
9.1
FRONT-MOUNT RADIO INSTALLATION
In a front-mount radio installation, total speaker cable length (of both cables) is approximately 10 feet
(308 centimeters). Therefore, to include service loops in these cables, the speaker must be mounted within
approximately 9.5 feet (290 centimeters) of the M7300 mobile radio.
1. Select a location for the speaker that will allow for proper listening range with a moderate volume
setting.
2. Install the speaker using the hardware and mounting bracket supplied with it. For the speaker's part
number, see Table 4-3 (page 22).
3. Route the speaker cable to the rear of the M7300 mobile radio.
4. Connect the M5300/M7300 Option Cable CA-012349-001 (item 5 in Table 4-3) to the DB-44
connector on the rear of the radio. Tighten the cable's two (2) jackscrews securely. See Section 11.1
for additional information on this cable.
5. Mate the Option Cable's 2-pin connector (identified P2) to the 2-pin connector on the end of the
speaker cable. A mild click will be sensed to confirm proper mating.
6. Route the cables out of the way of casual contact. Tie and stow as necessary.
9.2
REMOTE-MOUNT RADIO INSTALLATION
In a remote-mount radio installation, total speaker cable length (of both cables) is approximately five (5)
feet. Therefore, to include service loops in these cables, the speaker must be mounted within
approximately 4.5 feet of the installation's CH-721 control head.
1. Select a location for the speaker that will allow for proper listening range with a moderate volume
setting.
2. Install the speaker using the hardware and mounting bracket supplied with it. For the speaker's part
number, see Table 4-4 (page 22).
3. Route the speaker cable to the rear of the CH-721 control head.
4. Mate the 6-inch speaker cable (item 8 in Table 4-4) to the 2-pin connector at the rear of the control
head by visually aligning the ¾-moon-shaped keys of the connectors, and then pushing and turning
the outer locking ring of the cable connector clockwise until it stops. A mild click will be sensed to
confirm proper mating.
5. Connect the speaker cable's 2-pin plastic connector to the respective mating connector on the 6-inch
speaker cable.
6. Route the cables out of the way of casual contact. Tie and stow as necessary.
