c INSTALLATION PROCEDURES

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 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 cm2 (18 in2).

v PRECAUTIONS

When installing the transceiver with card edge connector, use the optional MBA-3 as described below.

D Attachment

Unscrew the 10 bottom screws, then remove the bottom q

cover from the transceiver.Unscrew the four rear plate screws. w

Disconnect the I/O cable connectors J3, J4, and coaxial e

J6 , and then remove the rear plate from the transceiver.

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’s PTT line, and connect pin 16 to the other 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.

D Audio line connections

Use #20 ~ #24 AWG wires for connections.

D 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 two or more transceivers in a stack, the mount-ing 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.
