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 ACCES” 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.
Stealth Mode
The stealth mode disables all tones and the display backlight so that
they do not reveal you are transmitting or otherwise indicate your pres-
ence. The speaker audio and display remain enabled. The stealth mode
can be selected by the STEALTH menu parameter (see page 35) or it can
be fixed in the on or off mode by dealer programming. There is no special
indication that this mode is selected except that “On” is briefly displayed
when it is selected by the menu parameter.
Time-Out Timer
The time-out timer disables the transmitter if it is keyed continu-
ously for longer than the programmed time. It can be programmed for 0.5
- 5.0 minutes or disabled entirely. If the transmitter is keyed continuously
for longer than the programmed time, the transmitter is disabled,
“TIMEOUT” is indicated in the display and the intercept tone sounds.
The timer and tone are reset by releasing the PTT switch.
