None if changing from a GMA 340 or
340H to a GMA 350.
If changing from a GMA 340 Dual
ADF version to either GMA 350 or
350H, see corrective action.
If changing to a GMA 350H, see cor-
rective action.
In most cases, none.
If the previous wiring was for the GMA
340 2ADF version, the DME
connection (if any) should be moved
to the GMA 350 AUX3 input.
If changing from GMA 340 to GMA
350H, note that the GMA 350H has
only one MUSIC input and these pins
will have no function. If the wiring
remains, no damage or change to
operation will occur. Most GMA 340
installations have the same source
wired to both music inputs resulting in
no wiring change necessary.

If previous GMA 340 wiring connected
this input to ground, default GMA 350/
350H configuration will result in a hot
(always heard) COPILOT ICS MIC
condition.
Option 1: Remove previous wiring.
Option 2: Using the GMA 350/350H
configuration tool, configure the
J3502-30 input for no function instead
of PTC KEY.
NOTE: The COM TX Mute feature is
still available with the configuration
tool.
