. Optional HM-75A functions
The optional HM-75A allows you to remotely select operating chan-
nels, open the squelch, etc. The switches on the HM-75A function
as follows.
~CAUTION: When connecting the HM-75A to the transceiver,
~ make sure that power to the transceiver is turned OFF, other-
~ wise the transceiver may malfunction.
