IMPORTANT

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.

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.

c

INSTALLATION PROCEDURES

1. Check the quantity of parts.

See z SUPPLIED ACCESSORIES.

2. Prepare miscellaneous items required for installation.

USING THE MBA-3

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.

PRECAUTIONS

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.

Notes 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.

D

Mounting bracket dimensions

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.
