Installation Procedure
The KX3-2M or 4M module mounts over the exposed area of the RF board in the bottom cover next to the
battery holders. It mounts above the KXAT3 Antenna Tuner. An adapter board is included in the kit for
those KX3s that do not have the optional Antenna Tuner.

Separate the Case Halves
Disconnect all cables attached to the KX3 and remove the KXPD3 paddles if installed.
Open the KX3 just as you would to install or remove batteries (see Internal Batteries in your
Owner’s Manual for details about how to do this).
Remove the internal batteries (if present).
We recommend removing the batteries whenever you work inside of your
KX3 to avoid damage that may be caused by an accidental short circuit.
