IMPORTANT
x
READ THIS INSTALLATION GUIDE CAREFULLY before
install the transceiver. This installation guide contains
important safety instructions.
NEVER install the transceiver where normal navigation of
the aircraft may be hindered.
NEVER
install an antenna near any aircraft projection,
engine, or propeller.
Install a circuit breaker between the aircraft battery and the
transceiver.
INSTALLATION PROCEDURES
c
1. Check the quantity of parts.
See z SUPPLIED ACCESSORIES.
2. Prepare miscellaneous items required for installation.
See miscellaneous items in z SUPPLIED
ACCESSORIES.
3. Prepare the required wiring.
See n CONNECTOR INFORMATION and m
CONNECTING THE CABLES FOR D-SUB 25 PIN.
• If you want to use the MBA-3 connector, see b USING
THE MBA-3 and , CONNECTING THE CABLES FOR
CARD EDGE CONNECTOR.
4. Assemble supplied mounting bracket and other parts.
See . MOUNTING BRACKET ASSEMBLY.
5. Cut the mounting hole.
See ⁄ 0 MARKING A MOUNTING HOLE.
6. Mount the transceiver into the mounting bracket.
See ⁄1 MOUNTING TO THE BRACKET.
7. Check the transceiver operation.
See ⁄ 2 OPERATION CHECK.
USING THE MBA-3
b
When installing the transceiver with card edge connector, use
the optional MBA-3 as described below.
D Attachment
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.

13.8 V DC
Power ground Circuit breaker
or 27.5 V DC
(10 A)
• 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 flight.
• Power Ground
Connect the transceiver power ground to the aircraft ground.
D Yoke-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.

D Transmit/receive interlock connections
When 2 transceivers are installed, connect pin 2 to the
other transceiver PTT line, and connect pin 16 to the other
's
transceiver interlock line to prevent both transceivers from
's
simultaneously transmitting.
However, when 2 transceivers are installed through a dual
audio panel, the connections are not necessary.
Check operation after installation.
Install the transceiver according to the procedures of this
installation guide.
The antenna should be spaced at least 40 cm (1.3 feet)
from any position occupied by any person on board the
aircraft or the vehicle.
PRECAUTIONS
v
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 flat metal surface or install a ground
plane of at least 120 cm 2 (18 in 2 ).
4. Connect the I/O cable connectors and coaxial onto the
MBA-3 as illustrated below.

5. Attach the MBA-3 to the transceiver with the five rear
plate screws.
6. Replace the removed bottom cover and 10 screws.
D Audio line connections
Use #20 ~ #24 AWG wires for connections.
