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 and the
intercept 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.
One use of this feature is to prevent a repeater from being kept busy
for an extended period by an accidentally keyed transmitter. It can also
prevent possible damage to the transmitter caused by transmitting for an
excessively long period.

ming. One of the following configurations are programmed.
Silent - All tones are disabled.
Key Beep - Only the key press tones are enabled.
Alert - All tones except the preceding key beep tones are enabled.
All Tones - All tones (both Key Beep and Alert) are enabled.

message is complete, scanning resumes (unless it has been disabled).
Scanning is turned on and off by the SCAN option switch (it is fixed
in the on or off mode if this switch is disabled). When scanning is
enabled by this switch, the green LED to the left of the channel display
