GENERAL FEATURES

Receive-Only Groups
Any group can be programmed for monitoring only (transmitting is
disabled). If the PTT switch is pressed with one of these groups selected,
the intercept tone sounds and “TX DSBL” is displayed.
Stealth Mode
The stealth mode disables the following tones and indicators so that
they do not reveal that you are transmitting or otherwise indicate your
presence. The speaker audio and display remain enabled in this mode.
• All tones (see “Tone Select” on page 30)
• The front panel transmit/busy indicator (see page 16)
• Display backlight
The stealth mode can be selected by an option switch or the
STEALTH menu parameter (see page 32), or is fixed in the on or off
mode by programming. There is no special indication that this mode is
selected except “On” is displayed under “STEALTH” in the menu mode.
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 on the lower line of the display, and the inter-
cept tone sounds. The timer and tone are reset by releasing the PTT
switch. Ten seconds before time-out occurs, a beep sounds to indicate that
time-out is approaching. There is also a timer that can be programmed to
prevent transmitting for up to one minute after time-out occurs.
One use of the time-out timer feature is to prevent a repeater from
being kept busy for an extended period by an accidentally keyed trans-
mitter. It can also prevent possible damage to the transmitter caused by
transmitting for an excessively long period.
