Before starting the scanner, make sure the SQL control is set to squelch off the noise on a
clear channel. Scanning is activated and deactivated by the [p] / [q] keys. Just press and
hold either key for more than ½-second to start the scanner. If the transceiver is in the VFO
mode (or on the CALL channel), the whole band will be scanned. If in the memory mode,
only the memories will be scanned.
The scanner pauses (and the decimal point blinks) whenever a signal is detected which is
strong enough to open the squelch. You have a choice of two scan-resume modes: either
Pause mode, in which the scanner pauses for as long as the carrier keeps the squelch open,
or the 5-second duration mode, in which the scanner pauses for five seconds and then
resumes scanning whether or not the signal is still present.
To set the scan-resume mode, press [F/M] and then [STEP(7)]. A small “P” or “5” at the
left indicates the current mode. Press [F/M] to change it, or just press [STEP(7)] alone to
return to the frequency display.
You can stop the scanner manually by pressing the PTT or an [p] or [q] key, or by
turning the DIAL knob.
NOTE: The scanner checks about 14 channels per second. To prevent this process from
being interrupted by the power saver, saver operation is automatically suspended
during scanning, resulting in some increase in power drain.

CANNING
When you have some busy channels stored in memories you may wish to skip them when
scanning other memories, but still have them available for manual selection. You can mark
a memory to be skipped by pressing [F/M] and then [SKIP(MR)] while the memory is
recalled. A tiny arrowhead will be displayed just to the right of the memory number box,
and this memory will be skipped during scanning (although you can still recall it manually).
To unmask a scan-skip memory, just repeat the same steps you took to mask it: select the
memory manually, and press [F/M] and [SKIP(MR)].

(PMS)
In addition to band and memory scanning, the FT-411
MK
Ⅱ
can scan between two frequen-
cies of your choice stored in the special memories labelled “L” and “U”:
•
Store the lower edge of the desired scanning range in memory “L”, and the upper edge
in memory “U”.
‚
With either memory “U” or “L” recalled, press the [SKIP(MR)] key. A dotted under-
line will appear at the bottom of the memory number box at the upper left.
You can now tune or scan as described previously, between the nearest multiples of 100
kHz (xxx.000, xxx.100, xxx.200, etc.) below memories “L” and “U”.
