Separate the two halves of the KX3 case by unplugging the battery cable and unplugging the flex cable
at the end next to the battery holders as shown in Figure 4. Gently lift up on each end of the flex cable
connector and rock it side to side to unplug it. When free, set the front panel assembly aside.

Install the Internal Coaxial Cables
Two miniature coaxial cables are used to carry RF signals. One cable carries a local oscillator signal from
the KX3 main RF board to the KX3-2M or 4M module. The second cable carries RF signals between the
KX3-2M or 4M module and an SMA antenna connector mounted on the end panel of the KX3 near the
BNC antenna connector. The coaxial cables are equipped with female Ultra Miniature Coaxial (UMC)
connectors that snap onto male UMC connectors on the KX3 RF board and the KX3-2M or 4M module
(see Figure 5).
