SCANS
Fine scan functions as programmed or ∂F scan, but
scan speed decreases when the squelch opens and
does not stop. The scanning tuning step shifts from
50 Hz to 10 Hz while the squelch opens.
q Select the scan screen from the start up screen by
pushing [(F-4)SCAN].
w Set for programmed scan or ∂F scan as described
on previous page.
e Push [
(F-1)PROG] or [(F-2)∂F] to start a scan.
- Decimal points blink while scanning.
r Push [(F-3)FINE] to start a fine scan.
- “FINE PROGRAM SCAN” or “FINE ∂F SCAN” ap-
pears.
t When the scan detects a signal, the scan speed
decreases but does not stop.
y Push [(F-1)PROG] or [(F-2)∂F] to stop the scan;
push [(F-3)FINE] to cancel the fine scan.

q If the start up screen is not selected (if [F-5]’s func-
tion is [EXIT]), push [F-5] one or more times to exit.
w Select memory mode.
e Select the desired operating mode.
- The operating mode can also be changed while scan-
ning.
r Push [
(F-4)
SCAN] to select the scan screen.
t Set [RF/SQL] open or closed.
- See p. 47 for scan condition.
- If the [RF/SQL] control function is set as RF control, the
squelch always opens. See pgs. 2, 56 for details.
y Push [(F-1)MEMORY] to start the memory scan.
- Decimal points blink while scanning.
u When the scan detects a signal, the scan stops,
pauses or ignores it depending on the resume set-
ting and the squelch condition.
i To cancel the scan, push [(F-1)MEMORY].
NOTE: 2 or more memory channels must be pro-
grammed for memory scan to start.
