READ THIS INSTALLATION GUIDE CAREFULLY before
install the transceiver. This installation guide contains impor-
tant safety instructions.
NEVER
install the transceiver where normal navigation of
the aircraft may be hindered.
NEVER
install an antenna near any aircraft projection, en-
gine, or propeller.
Install a circuit breaker between the aircraft battery and the
transceiver.

Power ground Circuit breaker
(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
two separate momentary push switches.

D Transmit/receive interlock connections
When two transceivers are installed, connect pin 2 to the
other transceiver PTT line, and connect pin 16 to the other
's
transceiver 's interlock line to prevent both transceivers from
simultaneously transmitting.
However, when two 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 in-
stallation 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.
DO NOT place the transceiver where hot or cold air blows di-
rectly on it.
AVOID placing the transceiver in areas with temperatures be-
low –20˚C or above +55˚C (–4˚F to +131˚F).
NEVER connect the transceiver to a power source using re-
verse polarity. Reverse polarity will damage the transceiver.
To prevent voltage drops, solder or crimp the cable lug when
b US-
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
2
plane of at least 120 cm (18 in
Connect the I/O cable connectors and coaxial onto the
r
MBA-3 as illustrated below.

Rear plate
Attach the MBA-3 to the transceiver with the five rear plate
t
screws.
y Replace the removed bottom cover and 10 screws.
