8. SCANS
∂F scan and Fine ∂F scan
Repeatedly scans within the ∂F span area. The
scan starts from the center frequency.

LIn a Fine scan (Programmed or ∂F), the scan
speed decreases when the squelch opens, but the
transceiver keeps scanning. The scan tuning step
changes to 10 Hz when the squelch opens.

4. Touch [∂F SPAN] several times to select the
span.
• Each touch changes the span.
5. Touch [∂F].
• The ∂F scan starts.
LWhen a signal is detected, the scan pauses
according to the "SCAN Resume" setting, and
then resumes.
LTo turn the TS function to scan by the frequency
step setting, touch the 100 kHz digit on the
frequency readout.
LTo cancel the scan, touch [∂F] again.
6. To switch to the Fine ∂F scan, touch [FINE].
• The scan frequency step changes to 50 Hz.
LTo return to the ∂F scan, touch [FINE] again.
