Elecraft KXAT3 - Manual (Page 4)

Taking ESD precautions remove the KXAT3 board from its packaging and mount it on the KX3 RF board
as shown in Figure 3. Be especially careful to ensure that all the pins of both connectors engage with their
opposites on the RF Board. You may find it easiest to engage P2 with J6 (near the battery holder) first so you
can see the pins more clearly. It is normal for part of the length of the pins on P2 to be visible when the
connectors are properly mated.
Figure 3. Installing the KXAT3.
Be sure you have plugged the cable to the BNC antenna connector into J1 on the KXAT3 module (see
Figure 3).
Replace the internal batteries, (if applicable).
Close the case and tighten all four thumb screws.
Turn to Option Module Enables in the Owner’s manual to enable the KXAT3. The KXAT3 will not operate
until this is done. Operating instructions and antenna recommendations are also included in the KX3 Owner’s
manual.
