Transmitting a Telstra (OTC) tone call

The tone call facility allows you to call a Telstra station using the transmission of a
simple signalling system–OTC tone call. It should be noted that whilst the tone call
facility is available it is recommended that, where ever possible, all calls to Telstra
are initiated by the selective call procedure—the preferred method of establishing
contact.
Before commencing this procedure, ensure the Voice Mute button is in the off
position (indicator off) and the antenna is tuned to the selected frequency.
The 'OTC Tone Call' button only operates on OTC designated channels.
