WA335 and WA336
The WA335 is for the UR1M transmitter. The WA335 is employed to replace the the transmitter's TA4M connector with a 3-pin LEMO connector. This modification requires unsoldering/soldering of the printed circuit board.
The WA336 is the LEMO connector for the cable of the lapel mic that must mate to the modified UR1M transmitter.
