You can stop or pause this activity using the Stop or Pause buttons. If you use
the Pause button, then restarting scanning using Scan Forward or Scan
Backward buttons will resume the action from the paused frequency. If you
stop scanning with the Stop button, then using the Scan Forward or Scan
Backward buttons will recommence scanning from the initial (or the last)
frequency again.

If no ranges are specified in the Ranges list, then activating scanning in the
Range mode will result in no action.
Range mode will result in no action.
Memory Scanning
The last scanning method is Memory Scanning. Here the receiver will step
through memory frequencies, starting with the first one to the last one, and
repeating the loop until a signal is found or until manually stopped.

repeating the loop until a signal is found or until manually stopped.
If a squelch value is stored with a memory, this value will then be used to
compare with the current signal level. If there is no value stored, the current
squelch value will be used as the scanning threshold.

It is possible to restrict scanned frequencies to particular memory groups only.
These groups can be selected from the Options | Scanning | Groups
window, accessible from the top bar menu. Groups can be enabled/disabled
using the check box Enable group restriction in the same window.

Note: Typical scanning speed for memory scanning is 40 channels/second.
This can be significantly reduced for frequencies which are close to each
other. For example, if the next frequency is closer than 10 kHz to the previous
one, and the specified bandwidth also falls within this 10 kHz distance, then
the receiver will not need to tune its hardware to the new frequency. Instead, it
will tune to the new frequency by software processing of the received
spectrum. This will result in tuning to the new frequency much faster. If
scanning speed is important, it is also advisable to sort the memories by
frequency, because the larger the tuning step, the longer it takes for the
receiver to settle on the new frequency.
