Turn the
VOLUME/POWER
knob clockwise to turn on the ra-
dio. The active display and channel indicators will become illu-
minated, indicating the status of the radio. The channel indicated
will be the same one on which you were operating when the ra-
dio was last turned off.
Setting the Channel
In 4-channel versions , press the CHANNEL button to change
channels.
In 40-channel versions , the display will show either a channel
number or a Scan Mode indicator ( Sc , Ur , SP or UP ). If a Scan
Mode indicator is displayed, press the SCAN button momen-
tarily so that a channel number is displayed; then press either the
UP (
p
) or DOWN (
q
) button to change channels.
Setting the Volume
Rotate the VOLUME/POWER knob clockwise to increase the
volume level. If no signal is present on which to adjust the vol-
ume level, push and hold in the
MONI button for two seconds;
the yellow “ MONI ” indicator will blink, and either background
noise or a voice signal will be heard. You may now adjust the
VOLUME/POWER knob for a comfortable listening level.
When you are done, press the MONI button momentarily to re-
turn to silent monitoring.
Transmitting
To transmit, wait until the “ TX/BUSY ” indicator is off (this in-
dicates that the channel is not in use). Then press the PTT ( P ush-
T o- T alk) switch on the side of the microphone; while holding in
the PTT switch, speak in a normal voice level across the face of
the microphone. During transmission, the red “ TX/BUSY ” indi-
cator will glow steadily. When you are done transmitting, re-
lease the
PTT switch; the VX-2000 will revert to the “receive”
mode.
The remaining instructions apply to 40-channel trans-
ceiver versions only
Special Transmitter Functions
If your VX-2000 is programmed for Busy Channel Lock-
Out , the transmitter will not activate when the PTT switch is
pressed unless the “ TX/BUSY ” indicator is off (so as to pre-
vent interference to other users of the same channel).
If the selected channel has been programmed for
Automatic
Time-Out , you must limit the length of your transmissions.
While transmitting with this feature activated, a “ beep ” will
sound ten seconds before the timer expires, and then another
“
beep ” sound as the timer expires: the “ TX/BUSY ” indica-
tor will shut off, and transmission will cease. Release the
PTT switch, listen for a moment, then press PTT again to
resume transmission. This feature prevents interference to
other users caused by a microphone which accidentally is
stuck in the “transmit” position (wedged between seats of a
car, etc.).

PERATION
Scanning
To activate scanning on your radio, first place the microphone in
its hanger. Now press the
SCAN
button momentarily. The radio
will scan in one of four available Scan Modes (detailed below),
and will halt when a signal is received which contains the correct
code to open your squelch. Scanning will resume automatically
either after a preset interval of a few seconds, or after the other
station stops transmitting (depending on how your radio was pro-
grammed).
The four Scan Modes, and their corresponding displays, are:
Display Scanning function
Sc
Scan all channels
Ur
Scan only user-selected channels
SP
Monitor one channel plus dealer-designated Priority Channel(s)
UP
Scan user-selected channels plus uer-designated Priority Channel(s)
The user-selected channels for the
Ur
and
UP
Scan Modes are
ones you can set up yourself, as described at the right. The
“Priority” channels are those on which signals will take prior-
ity over signals received on other channels; that is, if a signal
appears on a Priority Channel while another appears on a non-
priority channel, the Priority Channel signal will be heard, and
not the other.
Up to two of the installed channels may be designated by your
Dealer as pre-programmed Priority Channels for the
SP
mode
(the radio will not indicate which they are), and you can addi-
tionally program any two channels as “User Priorities” for the
UP
mode. In the
SP
mode, the non-priority channel will be the
last one displayed.
When a Scan Mode is displayed, you can select another by press-
ing the
SEL/PRI
button repeatedly (the display will cycle through
the above selections). Note that the radio will not scan if the
microphone is not in its hanger.
