Channel-Skip Scanning
Continuous-carrier stations like ATIS (Automatic Termi-
nal Information Service) or Weather Broadcast stations
inhibit scanner operation. Since these stations are always
active, the scanner will be halted repeatedly on their chan-
nels. Such channels can be set to be “Skipped” during
Memory scanning (MR, Book, WX, or BRS modes), if
you like, so as not to interfere with automatic channel scan-
ning:
Recall the Memory Channel to be skipped during scan-
ning.
Press and hold the key for 2 seconds. The “ ”
icon will appear at the left
of the frequency display,
indicating that the chan-
nel is to be ignored dur-
ing scanning.
Later, to re-enable the memory channel for scanning,
repeat the first two steps. The “
” icon will disap-
pear by the channel you have just re-enabled.
Note
: A memory set to be “Skipped” is still accessible for
manual memory selection using the DIAL selector knob.

This feature allows you to set sub-band limits for either
scanning or manual VFO operation. For example, you
might with to set up a limit of COM band (118.000 MHz
to 136.975 MHz. Here’s how to do this:
Set the radio to the VFO mode by pressing the
key and set the radio to the AIR band by pressing the
key, if necessary.
Using the techniques learned earlier, store 118.000
MHz into Memory Channel “
Lch ” (the “ Lch ” desig-
nates the Lower sub-band limit).
Likewise, store 136.975 MHz into Memory Channel
“
Uch ” (the “ Uch ” designates the Upper sub-band
limit).
Switch to the Memory mode by pressing the key
once, then rotate the DIAL to select Memory Channel
“ Lch .”
Press and hold in the key for 2 seconds to start
PMS operation; the “ MR ” label will be replaced by
“ PMS ” in the upper left-hand corner of the display.
Tuning and scanning (pressing the key) will now
be limited within the just-programmed range.
Note : The PMS feature will not engage if a BRS channel
is stored in either the “
Lch
” or “
Uch
” memory slot.
