MOUNTING BRACKET ASSEMBLY

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.

MOUNTING TO THE BRACKET
CAUTION:
Make sure that the cable between the trans-
ceiver and front panel is securely connected. The trans-
ceiver may not function properly when loose or when a
wrong connection is made.
Improper cable connection can cause damage and result
in severe non-warranty repair.
Use two pairs of #18 AWG wire for the power and power
connections.

For the yoke-mounted memory and frequency exchange
switches, use a two-position spring loaded rocker switch or
two separate momentary push switches.

Transmit/receive interlock connections
When two transceivers are installed, connect pin N to the
other transceiver
’s
PTT line, and connect pin 9 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.
Use #24 AWG wire for the connections.
