PRECAUTIONS
n
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
directly on it.
AVOID placing the transceiver in areas with temperatures
below –20˚C or above +55˚C (–4˚F to +131˚F).
NEVER connect the transceiver to a power source
using reverse polarity. Reverse polarity will damage the
transceiver.

The conditions and tests required for TSO approval of
this article are minimum performance standards. Those
installing this article, on or within a specific type or class
of aircraft, are responsible for determining that the aircraft
installation conditions are suitable for the TSO article.
CONNECTING THE CABLES FOR D-SUB 25 PIN

• 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'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.
Install the transceiver according to the procedures of this
installation manual.
The antenna should be spaced at least 50 cm (1.6 feet)
from any position occupied by any person on board the
aircraft or the vehicle.
