BASIC OPERATION

■

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

q

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

cording to your System Operator’s instructions.

 • This  may  not  be  necessary,  depending  on  the  preprogram-

ming.

 • Refer to pages 10 and 11 for selection.

w

  Push [Call] (assigned to one of the dealer programmable 

keys).

e

  After transmitting, the remainder of your communication 

can be carried out in the normal fashion.
