Scanning Operation
FT-891 Advance Manual
PMS (Programmable Memory Scanning)
To limit scanning (and manual tuning) within a particular frequency range, the Program-
mable Memory Scanning (PMS) feature utilizes nine special-purpose memory pairs (“P1L/
P1U” through “P9L/P9U”). The PMS feature is especially useful in helping you to observe
any operating sub-band limits, which apply to your Amateur license class.
1. Store the Lower and Upper tuning/scanning
limit frequencies into the memory pair “P1L”
and “P1U”, respectively, or any other “L/U”
pair of memories in the special PMS mem-
ory register.
2. Press the [
V/M
] key to enter the “Memory”
mode.
3. Rotate the
MULTI
function knob to select
memory channel “P1L” or “P1U”.
4. Turn the
DIAL
knob slightly (to activate
memory tuning). Tuning and scanning are
now limited to the range within the P1L/P1U
limits until the [
V/M
] key is pressed again to
return to the memory channel.

5. Press and hold in the microphone [
UP
] or [
DWN
] key for one second to start scanning
in the specified direction.
6. To cancel scanning, press the [
V/M
] key.
7. One more press of the [
V/M
] key momentarily to display the “MEMORY CHANNEL”
list screen.
r
If the scanner halts on an incoming signal, the decimal point between the “MHz” and
“kHz” digits of the frequency display will blink.
r
If the incoming signal disappears, scanning will resume in about five seconds.
r
On the SSB/CW and SSB-based Data modes, the scanner will pause on a received
signal, then will step across the signal very slowly, giving you time to stop the scan, if
you like. However, in these modes on the VFO, the scanner does not stop.
r
If the scan has paused on a signal, pressing the microphone [
UP
] or [
DWN
] key will
cause scanning to resume instantly.
r
If the
DIAL
knob is rotated while scanning is in progress, the scanning will continue
up or down in frequency according to the direction of the
DIAL
Knob rotation. (in other
words, if the dial is rotated to the left when scanning toward a higher frequency, the
direction of the scan will reverse.)
r
If the microphone PTT button is pressed during scanning, the scanner will halt at
once. Pressing the PTT button during scanning will not cause transmission.
