CONTROLS & CONNECTORS

Front Panel

4 channel version

40 channel version

1. Microphone Jack
   Connect the microphone plug to this jack.

2. MONI Button & Indicator
   This button selects the “squelch” (receiver mute) mode. When the yellow indicator is off, “tone” or “coded” squelch is active. When the indicator glows steadily, only “noise squelch” is active, and any signal present on the channel will be heard. When the indicator is blinking, the squelch is disabled, and background noise will be heard if no signal is present.

3. A Button & Indicator
   This button is provided for an Accessory function such as H10H/Low Power selection, “TALK-AROUND”, or “CALL ALERT” functions. The green “A” indicator will be illuminated when this function is active.

4. VOLUME and POWER ON/OFF Knob
   This knob adjusts the receiver volume, and turns the radio off when turned all the way to the left into the click-stop.

5. TX/BUSY Indicator Lamp
   This lamp blinks red WQen the channel is busy, and glows steadily red during transmission. Do not transmit when this indicator is blinking, ~s a courtesy to other users of the channel.
   The following item is unique to the 4-channel radio versions:

6. CHANNEL Numbered Indicators & Button Press the CHANNEL button to select the operating channel; the channel number currently in use will light up on the display panel.
   The following items are unique to the 40-cliannel radio versions:

   External Transmit Audio input, PTT (Push To Talk), Squelch, and Receive Audio output signals may be obtained from this connector for use with accessories such as a data transmission/reception modem, etc.

OPERATION

Power ON/OFF

Tum the VOLUME/POWER knob clockwise to turn on the radio. The active display and channel indicators will become illuminated, indicating the status of the radio. The channel indicated will be the same one on which you were operating when the radio 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 momentarily so that a channel number is displayed; then press either the UP( ) or DOWN( ) button to change channels.

Setting the Volume

Rotate the VOLUME/POWER knob clockwise to increase the volume level. Ifno signal is present on which to adjust the volume 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 return to silent monitoring.

**Transmitting

**

To transmit, wait until the “TX/BUSY” indicator is off (this indicates that the channel is not in use). Then press the PTT (Push-To-Talk) 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” indicator will glow steadily. When you are done transmitting, release the PTT switch; the VX-2000 will revert to the “receive” mode.
The remaining instructions apply to 40-channel transceiver 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 prevent 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 transmission . 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” indicator will shut off, and transmission will cease. Release the PTT S\vitch, 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.).

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 aftet the other station stops transmitting ( depending on how your radio was programmed). The four Scan Modes, and their corresponding displays, are:

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 wi11 take priority 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 preprogrammed Priority Channels for the SP mode (the radio will not indicate which they are), <;1nd you can additionally 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 pressing the SEUPRI button repeatedly (the display ,viii cycle through the above selections). Note that the radio “viii not scan if the 1nicrophone is not in its hanger.

USER-PROGRAMMABLE CHANNEL SELECTIONS

You can program a list of channels to be scanned, and up to two channels to be monitored on a ”priority” basis. Your selections will be maintained in memory until you change or delete them.

Setting of these channels involves two small ”Dot” indicators at the top of the channel display field. The Dot to the left of the first digit is the ”P” (Priority) indicator, while the Dot to the left of the second digit is the ”E” (Enable for Scanning) indicator.

To create or modify the Scan and Priority selections, first tum the radio off. Now press and hold in the SCAN button while you tum the transceiver back on; continue to hold the SCAN button in for two seconds after the radio has come on, then you may release it.

Now press the UP ( ) or DOWN ( ) button repeatedly, and note whether or not the ”E” (right dot) or “P” (left) dots appear on any of your channels. If a dot appears by any channel, it means that it has been designated as either a Scan Enabled or Priority channel, respectively.

To enable or disable a channel from the User Scan list, press the SEUPRI button momentarily. The ”E” dot will appear or disappear, as appropriate ..

To change the Priority Channels, first cancel both by selecting either, and then pressing the SEL/PRI button momentarily. Now select the channel you wish to designate as the 1st Priority Channel, and hold in the SEUPRI button for 2 seconds, until a beep sounds and the ”P” indicator blinks. If you wish to designate a 2nd Priority Channel, move to that channel, and again hold in the SEUPRI button for 2 seconds; this time, the ”P” indicator will glow, but will not blink.

If you have deleted a channel from Priority status, you must re-enable it for scanning if you want it to be included on your Scan List. Press the SEL/PRI button momentarily to do this.

Coded Squelch – the MONI Button

Your transceiver may be programmed so that when the microphone is removed from its hanger, coded squelch is defeated, and you can hear any signal on the channel (the yellow “MONI,, indicator will be lit). You can get the same result, without lifting the microphone, by pressing the MONI button momentarily. To avoid listening to unnecessary chatter, keep the microphone in its hanger, and pre.s s the MONI button when necessary to turn the yellow indicator off ( unless you want to listen to other calls on the channel).

Holding the MONI button in for two seconds defeats both the coded squelch and noise squelch, so background noise can be heard (the “MONI” indicator will blink in this case). Press the MONI button momentarily to return the yellow indicator to its previous state (either off or steadily on).
