GENERAL FEATURES

A power turn-off delay allows features such as the horn alert and call indicator to remain active for a time after the ignition switch is turned off. At the same time, advantages of ignition switch control are utilized such as preventing battery discharge that may occur if the transceiver is acci- dentally left on for an extended period (see page 54).

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. This tone can be programmed so that it sounds on 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 30) or system operator programming. Either a standard or loud (two-pitch) tone can be programmed.

On 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 the PTT switch is held down, the system is accessed and the proceed tone sounds when it is no longer busy. If an out-of-range condition occurs, the intercept tone sounds and “OUT- RNGE” is indicated in the display. 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 44). The proceed tone then does not sound if the channel is busy. Otherwise, the proceed tone (if enabled) sounds on conventional systems even if the channel is busy.

With all operating modes, if encryption is used, a 0.9-second delay occurs before this tone sounds and two beeps are heard instead of one. A short delay may also occur with conventional calls. These delays ensure that the radio path is complete before you begin talking so that part of your first word is not lost.
