BASIC OPERATION

■

 

When your system employs tone signaling (excluding CTCSS 
and DTCS), the call procedure may be necessary prior to voice 
transmission. The tone signalling employed may be a selec-
tive calling system which allows you to call specific station(s) 
only and prevent unwanted stations from contacting you.
q

  Select the desired TX code channel or 2/5-tone code 

according to your System Operator’s instructions.

  • This may not be necessary depending on programming.
  • Refer to pgs. 13 or 14 for selection.

w

  Push the call key (assigned to one of the dealer pro-

grammable keys: [Up], [Down], [P0], [P1], [P2], [P3], 
[Emergency] and [Monitor]) or [PTT].

e

  After transmitting a 2/5-tone code, the remainder of your 

communication can be carried out in the normal fashion.

 1. Pause briefly after pushing [PTT].

your mouth, then speak into the microphone at a nor-
mal voice level.
