3-7.4.1 Scan.
NOTE
Before performing a scan function, frequencies and
other parameters to be sampled should be determined
and set into designated memory channels.
Scan is the sequential continuous recall of a sequence of memory channels. The CPU in the receiver uses the data stored in each
channel to select frequency, mode, bandwidth, squelch level, gain, dwell time, bridge time and all other stored parameters to
operate the receiver. The receiver will stop on a frequency (for the current dwell time) when a received signal exceeds the
squelch level set in the channel. If the signal goes away before the dwell timer has timed out, the receiver will continue to scan.
If the dwell timer times out before the signal goes away the receiver continues the scan. If the dwell time is set to zero, the
receiver remains on frequency until the signal falls below the squelch level, and then continues the scan. The operator may
offset the squelch level from the value set in each memory channel before starting the scan.
