BASIC OPERATION

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.

cording to your System Operator’s instructions.
