xIMPORTANT
cINSTALLATION PROCEDURES
NEVER bend the cables sharply or place the cables too near
the aircraft control cables.
NEVER connect the transceiver to a power source
using reverse polarity. Reverse polarity will damage the
transceiver.
DO NOT place the transceiver where hot or cold air blows
directly on it.
DO NOT place the transceiver in areas with temperatures
below –20˚C or above +55˚C (–4˚F to +131˚F).
To prevent voltage drops, solder or crimp the cable lug when
connecting the DC power cable to the power supply.
Use a 50 Ω, vertically polarized, VHF air band antenna.
VSWR should be less than 2.5:1.
Mount the antenna on a at metal surface or install a ground
plane of at least 120 cm2(18 in2).
vPRECAUTIONS
When installing the transceiver with card edge connector, use
the optional MBA-3 as described below.
DAttachment
1. Unscrew the 10 bottom screws, then remove the
bottom cover from the transceiver.
2. Unscrew the four rear plate screws.
3.
Disconnect the I/O cable connectors J3, J4, and coaxial
J6, and then remove the rear plate from the transceiver.

• Circuit breaker
To prevent physical damage, a 10 A circuit breaker MUST be
installed in the DC power line in the aircraft. Install the circuit
breaker in the aircraft breaker panel or instrument panel to
ensure easy access during ight.
• Power Ground
Connect the transceiver power ground to the aircraft ground.
DYoke-mounted memory and frequency exchange
switches
For the yoke-mounted memory and frequency exchange
switches, use a two-position spring loaded rocker switch or 2
separate momentary push switches.

DTransmit/receive interlock connections
When 2 transceivers are installed, connect pin 2 to the
other transceiver’s PTT line, and connect pin 16 to the other
transceiver’s interlock line to prevent both transceivers from
simultaneously transmitting.
However, when 2 transceivers are installed through a dual
audio panel, the connections are not necessary.
DAudio line connections
Use #20 ~ #24 AWG wires for connections.

DNotes for making the mounting hole
The transceiver can be mounted securely in the supplied
mounting bracket.
Remember to allow adequate space for installation of
cables and connectors.
When installing 2 or more transceivers in a stack, the
mounting bracket should be 1.3 mm (0.05″)apart.
The mounting bracket has 0.6 mm (0.024″)dimples in the
top, bottom, and both sides for proper spacing.
Mark and cut the mounting holes.
To support the mounting bracket, the rear mounting bosses
should be attached to the airframe.
