GENERAL FEATURES

Proceed (Clear-To-Talk) Tone

This is a short tone that sounds shortly after the PTT switch is pressed to indicate that the radio system has been accessed and speaking can begin. The transceiver can be programmed so that this tone sounds on LTR-Net and LTR systems but not conventional systems. In addition, this and other tones can be disabled on all systems by the TONES menu parameter (see “Tone Select” on page 26) or system operator programming.

On LTR-Net and LTR systems, if the radio system is busy when making a call, the busy tone sounds instead of the proceed tone and “BUSY” is indicated on the bottom line of the display. If an access attempt is unsuccessful, such as because of an out-of-range condi- tion, the intercept tone sounds and “NO ACCES” is indicated in the display. When the “NO ACCES” condition, the PTT switch must be released to make another call attempt. Refer to page 47 for more information on the busy and intercept tones.

On conventional systems, the Transmit Disable On Busy feature can be used to automatically perform monitoring (see page 46). The proceed tone then does not sound if the channel is busy. Otherwise, the proceed tone (if enabled) sounds on conven- tional systems even if the channel is busy. If encryption is used, two tones sound instead of one to indicate that an encrypted call is being transmitted. With other calls, a standard (single beep) or distinctive (3-beep) tone may be used. With special and telephone calls, the proceed tone may sound on only the initial access.

Receive-Only Groups

Any group can be programmed for monitoring only (transmit- ting is disabled). If the PTT switch is pressed with one of these groups selected, the intercept tone sounds and “TX DISBL” is displayed.
