Option Select
The OPTION menu parameter can be used to control an accessory
that may have been installed by your system operator. The enabled condi-
tion is indicated by in the display.
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 to be a single or distinctive (3-
beep) tone. With encrypted calls, a special double beep sounds.
This tone always sounds with LTR-Net and LTR standard calls if
tones are enabled by the TONES menu parameter (see “Tone Select” on
page 28) or system operator programming. It can also be programmed to
sound with conventional calls and/or LTR-Net and LTR auxiliary and
telephone calls (first access only).
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 in the display. If an access attempt is unsuccessful,
such as because of an out-of-range condition, the intercept tone sounds
and “NO ACESS” is indicated in the display. Refer to page 53 for more
information on these conditions.
If the proceed tone is enabled on conventional systems and the
Transmit Disable On Busy feature is used to automatically perform moni-
toring (see page 51), the proceed tone does not sound if the channel is
busy. Otherwise, it sounds even if the channel is busy.
Receive-Only Groups
Any group can be programmed for monitoring only (transmitting
disabled). If the PTT switch is pressed with one of these groups selected,
the intercept tone sounds and “TX DISBL” is displayed.
