quires External Alarm ON/OFF switch Option SU02

on or off.
PUBLIC ADDRESS RELAY
The Public Address Relay switch (19C851585P6) is sup-
plied with the Public Address Control Panel Option and re-

relay provides automatic switching of the public address audio
to an external speaker when the microphone is keyed. Also, a

either the internal speaker or the external speaker. The relay
may be ordered separately from the PA Control Panels as Op-
tion SU03 for use as an internal/external speaker switch.The
public address relay connects to P2 of the option cable.

Remote mount Option CB01 (19A705306G1 & G2) allows
controlling the main radio assembly remotely from the Front
Cap Assembly. The Front Cap is removed from the main radio
assembly and mounted to a rear housing containing an inter-
face board (supplied with the option). A new front cap (without
any controls or displays) containing an interface board is
mounted to the radio assembly. A system cable (normally 18
feet supplied) is used between the two units. A 20 foot power
cable is also supplied for the radio assembly.
DC REMOTE CONTROL OPTION
The DC Remote Control Board Option CY01
(19A704686P7) is used to interface with a remote control con-
sole and mounts inside the AC Power Supply Option. The
board provides remote single frequency transmit and receive
and Channel Guard disable control. The board connects to P2
of the option cable Option CC0l.
SERVICE OPTIONS
Test Point Adapter Box Option TQ2370 (19B801494P1) al-
lows receive audio monitoring and transmit audio injection
without opening the radio. The adapter connects between the
microphone and the radio, providing test points for all 10 pins
of the microphone connector.
Service Cable 19A704875P1 provides an extension be-
tween the Audio Board and the Logic Board. Both sides of the
Audio Board are available for servicing using the cable.
Service cable 19B801348P4 provides a 2 foot extension
between the 9 pin "D" connectors (J701 and P701) on the
Logic Board and Control Board. The Front Cap Assembly may
be serviced using this cable.
To allow easier servicing of the Front Cap Assembly,serv-
ice cable 19A705235P2 provides a longer ribbon cable (2 feet)
between the System Board and the Control Board connectors
J902 and J901. This longer cable is not required for most serv-
ing. The radio’s ribbon cable is usually adequate in length if
the cable is not looped through the front of the radio’s assem-
bly.
