BASIC OPERATION

Call procedure
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 selec-
tive calling system which allows you to call specific station(s)
only and prevents unwanted stations from contacting you.
