RXPAD [ON/OFF]
This command enables or disables the receive attenuator for the receive audio
level. Entering the
RXPAD
command without a parameter shows whether the
attenuator is
ON
(enabled) or
OFF
(disabled). Entering the
RXPAD
command
followed by
ON
enables the receive attenuator; entering
OFF
disables it.
RXTOT [NONE, 1-1440]
The
RXTOT
command selects or displays the receive timeout timer value in
minutes. This timer triggers an alarm (event 12) if data is not detected within
the specified time.
Entering the
RXTOT
command without a parameter displays the timer value in
minutes. Entering the
RXTOT
command with a parameter ranging from 1 to
1440 resets the timer in minutes. Entering the
RXTOT
command with the
parameter
NONE
disables the timer.
SCD [0-255]
This command sets or displays the amount of time to wait after a de-key
request before actually de-keying the radio. Entering the
SCD
command
without a parameter displays the timer value in milliseconds. Entering the
SCD
command with a parameter ranging from 0 to 255 resets the timer in
milliseconds. The default setting is 0, which means that the radio will de-key
immediately following removal of a keying signal.
Should you experience problems with repeater operation after changing the
CTS
,
PTT
or
SCD
values, contact GE MDS.
