Scanning Features
VFO Scanning
You can start scanning on MAIN VFO-A by
holding the microphone UP or DWN button for 1/2
second (the receiver squelch does not have to be
closed in this case). To increase the scan speed
(x10) press either the microphone FST button (mo-
mentary-type) or the front panel FAST button.
Scanning continues up or down until a button is
pushed, or else "loops-around" when the upper or
lower receiver limits are reached.
Scan speed is determined by the receiver
"dwell time" using menu function 2-4. Dwell time
is the duration that each channel is sampled for
activity as the receiver scans up or down and is
adjustable from 1 msec (fast) to 100 msec (slow-
est). Try experimenting with different durations
until you reach the desired scan rate.
Memory Scanning
The 99 memories in the FT-1000MP offer
some choices regarding how they are scanned,
and, after the following brief description, you can
decide how to tailor scanning for your operating
needs.
When receiving on a recalled memory (with
(MEM) displayed), you can scan all stored memo-
ries by just holding the microphone DWN or UP
button for ¥ second to start. If you want scanning
to pause on signals, you must first adjust the SQL
control to silence the receiver (green indicator
off) on a clear channel. Scanning pauses on any
channel having a signal strong enough to open
the squelch, and the two decimal points in the
frequency display blink. You may need to readjust
the SQL control to prevent scanning from stopping
on only background noise. Scan speed is not
affected by the microphone or panel FAST buttons,
but is configured by menu selection 2-3. The
memory scanning "dwell time" is adjustable from
100 (fast) ~ 1000 msec (slow).
To stop scanning, press the PTT switch (no
transmission will occur), or a microphone button
again. When scanning, keep in mind that the IPO
and ATT selections also affect the squelch thresh-
old by changing receiver front-end sensitivity.

Scan Resume Mode
There are three choices that determine how
scanning will respond when activity is detected.
Scan resume operation is configured by recalling
menu selection 2-1, and choosing the desired
mode. Below is an outline of each scan resume
mode and how it operates.
Carrier Stop (default) - With the squelch
closed, scanning pauses on signal activity, then
resumes soon after the carrier disappears. With
the squelch open, scanning will not continue un-
less the receiver is quieted again (SQL control).
Carrier Timed Stop - With the squelch closed,
scanning pauses on activity, then resumes auto-
matically after a preset duration (5 seconds by
default), whether signal activity remains or not
(time-delay resume).
Carrier Timed Slow - With the squelch closed,
scanning slows down (but doesn't stop) for a
preset duration (5 seconds by default), when ac-
tivity is detected.
For the Timed Stop and Timed Slow modes,
the pause duration can be set between 1 and 10
seconds with menu selection 2-7, or else the scan
pause (resume) feature can be disabled com-
pletely using menu selection 2-0. If disabled,
scanning will not stop for any activity.
Memory Scan Skip
By default, all programmed memories are in-
cluded for scanning. However, you can "flag"
some of them to be skipped while scanning. To do
this, recall the memory you want to be skipped,
and hold either front panel or microphone FAST
button while pressing momentarily so the
"dash" between the group number and memory
channel number disappears. If you have flagged
a memory to be skipped, and later want to enable
it again, just repeat the FAST + [ck] procedure.
