Scan Rate
Scan Resume Time

Selcall Preamble
SSL Level
This is the default mute setting. This is the setting that the transceiver will have initially after
transferring the transceiver configuration.
When this setting is enabled, the transceiver mute is always “open”.
This setting enables the syllabic mute which "opens" when speech is detected.
This mute "opens" when the received signal exceeds the set SSL level.
This setting enables the selcall mute which "opens" when the transceiver receives a valid
selcall.
Sets the scan rate on a non-selcall scan channel when scanning. On selcall channels the
rate is fixed at 500 milliseconds.
Scan resume time sets the time delay, after the last key press or PTT activity, before the
transceiver automatically resumes scanning. Selecting “Off” disables the scan resume
function.
Sets the time that the transceiver will remain on a scan channel AFTER the scan stop
condition becomes invalid.
This is the length of pre-amble sent before the data portion of a selcall signal. The greater
the number of channels that are set for selcall scanning the longer the selcall pre-amble
length should be. I.e. scanning two channels will take 1 second, therefore the pre-amble
length should be set to more than one second. Scanning six channels will take 3 seconds,
therefore the pre-amble length should be set to more than 3 seconds.
Sets the signal level that the signal strength mute will "open" at. i.e. if you wish have the SSL
mute open on signals that result is a signal strength indication of two signal strength bars on
the transceiver display, set two signal strength bars in this option.
