Two-Tone Squelch (SQ) System
The radios will support Motorola-Format, Two-Tone (Type 99) decoding. This is receive only,
decode only feature. It will allow a dispatcher to call individuals and groups. Each System/Group
will be programmable to respond to any combination of the code, with a distinctive alert for each
System/Group. The alert format consists of two tone sequences, first the ID of the radio being
called, then the ID of the calling radio.
This feature is programmed by the dealer (per customer‟s request) and is not activated /
deactivated by the user. The user interface consists of the radio emitting the tones being
broadcast. At this point, the radio will enter Unmuted Rx mode and remain in this mode until the
PTT signal is inputted.
