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 
specific station(s) only and prevents unwanted stations from 
contacting you.

cording to your System Operator’s instructions.

  • This may not be necessary depending on programming.
  • Refer to pages 9–10 for selection.

w

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

keys).
