The VX-3R/E ’s scanning features include a two-channel scanning capability, which allows
you to operate on a VFO or Memory channel, while periodically checking a user-defined
Memory Channel for activity. If a station is received on the Memory Channel which is
strong enough to open the Squelch, the scanner will pause on that station in accordance
with the Scan-Resume mode set via Set Mode Item 75:
SCN.RSM . See page 54.
Here is the procedure for activating Priority Channel Dual Watch operation:
1.
Press the [ V/M
] key momentarily to enter the Memory Recall mode, if you are not
using memories already.
2. Press and hold in the [
F/W
] key for one second, then rotate
DIAL
knob to select the
memory channel you wish to be the “Priority” channel.
Note : Do not forget to pull the
DIAL
knob to rotate the
DIAL
knob.
3. Press the [
BAND
] key. The “
PRI
” icon will appear above of the
volume level indicator, indicating it is the Priority channel.
4. Now set the
VX-3R/E
for operation on another memory chan-
nel, or on a VFO frequency.
5. Press and hold in the [ V/M
] key for one second. The display will remain on the VFO or
memory channel selected. However, the “ DW ” icon will appear
on the display, and every five seconds the VX-3R/E will check
the Priority Channel for activity. If a station appears on the Prior-
ity Channel, the radio will pause on that channel, as described
previously.
The receiving time interval (ratio) between the current channel (or VFO frequency) and
Priority channel may be customized via Set Mote Item 65:
PRI.TMR
.

Press and hold in the [ TXPO
] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 65:
PRI.TMR
.
Note
: Do not forget to pull the DIAL knob to rotate the DIAL
knob.
3. Press the [ TXPO
] key momentarily to enable adjustment of this
Set Mode Item.

DIAL
knob to select the desired time interval. Avail-
able selections are 0.1S - 0.5S (0.5S/step) and 1.0S - 10S (0.5S/
