v INSTALLATION LIMITATION

The conditions and tests required for TSO approval of
this article are minimum performance standards. Those
installing this article, on or within a specic type or class
of aircraft, are responsible for determining that the aircraft
installation conditions are suitable for the TSO article.

TSO articles must have separate approval for installation
in an aircraft. The article may be installed only if performed
under 14 CFR part 43 or the applicable airworthiness
requirements.

b INSTALLATION PROCEDURES , CONNECTING THE CABLES FOR D-SUB 25 PIN

1. Check the quantity of parts.

Refer to z SUPPLIED ACCESSORIES.

2. Prepare miscellaneous items required for installation.

Refer to miscellaneous items in z SUPPLIED
ACCESSORIES.

3. Prepare the required wiring.

Refer to m CONNECTOR INFORMATION and ,

4. Assemble supplied mounting bracket and other parts.

Refer to . MOUNTING BRACKET ASSEMBLY.

5. Cut the mounting hole.

Refer to ⁄0 MARKING A MOUNTING HOLE.

6. Mount the transceiver into the mounting bracket.

Refer to ⁄1 MOUNTING TO THE BRACKET.

7. Check the transceiver operation.

Refer to ⁄2 OPERATION CHECK.

n PRECAUTIONS

16 17

14 25

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.

m CONNECTOR INFORMATION

D D-sub 25-pin

12345678

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 at metal surface or install a ground
plane of at least 120 cm

(18 in2).

• 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 ight.

• Power Ground

Connect the transceiver power ground to the aircraft
ground.

NOTE: If any external intercom system is in use, we
recommend that you disable the transceiver’s intercom
function to prevent degradation of the audio signal.
If any degradation exists, leave pin 17 disconnected and
disable the transceiver’s intercom function by following the
steps below.

1. While holding down [DUAL], rotate [VOL] to turn ON

the transceiver.

• The conguration menu is displayed.

2. Rotate [O-DIAL] to select “INCOM MODE.”

3. Rotate [DIAL] to set “INCOM MODE” to OFF.

4. Push [RCL] to exit the Configuration menu and restart
the transceiver.
