Refer 

Appendix A

 for antennas, batteries and other applicable accessories.

*

The radio’s model number and FLASHcode are required when placing an order for the Main Board.

•

The model number and (sometimes) the FLASHcode can be found on the FCC label on the back of the radio.

•

The model number and the FLASHcode can be found by putting a Model 1.5, 2 or 3 radio into the Test Mode.

•

The model number and FLASHcode can be found by using the Programming Cable (PMKN4012B or  PMKN4013C) and the CPS to 

read a Model 1.5, II, or III radio.
