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
IMEM)
displayed), you can scan all stored memo-
ries by just holding the microphone

button for '/2 second to start. If you want scanning
to pause on signals, you must first adjust the

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

control to prevent scanning from stopping
on only background noise. Scan speed is not

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.
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
