F scan searches for signals within the specified
range with the displayed VFO or memory channel fre-
quency as for center frequency. The frequency range
is specified by the span.
q
Push [V/M] to select VFO mode or memory mode,
as desired.
w
Set center frequency of the
∂
F scan.
e
Push [MENU] to select
M2
.
r

• See p. 68 for scan condition.
• If the [RF/SQL] control function is set as “AUTO,” the
squelch is always open in SSB, CW and RTTY modes.
t
Set the
∂
F span by pushing [F4

• ±5 kHz, ±10 kHz, ±20 kHz, ±50 kHz, ±100 kHz,
±500 kHz and ±1 MHz are selectable.
y
Push [F2

F
] to start the
∂
F scan.
• Decimal points blink while scanning.
u
When the scan detects a signal, the scan stops,
pauses or ignores it depending on the VSC, resume
setting and the squelch condition.
i
Push [F2
∂
F
] to cancel the
∂
F scan.
• Rotating the tuning dial during scan also cancels scan
operation.

During
∂
F scan, push [F3

] to switch between
∂
F scan and fine
∂
F scan operation.
e
