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.

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 specific 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.
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.
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
).
