Radio Gear. Radio Chest Harness. Ordering Info. Contact Info. Discontinued Radio Guides. Mini-Manuals Some customers have been asking for our older, discontinued ham radio guides. Availability of accessories may vary. Some accessories are supplied as standard per local requirements, while others may be unavailable in some regions. This product is designed to perform optimally when used with genuine Vertex Standard accessories. Consult your Vertex Standard dealer for details regarding these and any newly-available options.

Connection of any non-Vertex Standard-approved accessory, should it cause damage, may void the Limited Warranty on this apparatus. Connect the supplied rubber flex antenna or an- other antenna presenting a Ohm impedance here. Turn this control clockwise to turn the radio on and to increase the volume. Counterclockwise rotation into the click-stop will turn the radio off. This inner position detented rotary switch is used for setting the operating frequency, and also is used for menu selections and other adjustments.

The display shows the current operating conditions, as described on the next page. These 16 keys select many of most important operating features on the VX The functions of the keys are described in detail on the pages to follow.

This indicator glows green when the squelch opens, and turns red during transmit. Press this switch to transmit, and release it to receive after your transmission is completed. Pressing this switch disables the noise squelching action, allowing you to hear very weak signals near the background noise level temporarily.

Press the [F] key on the keypad first, then press this switch to enable to adjustment of the squelch threshold level. See page 61 for details. See page 79 for details. The supplied antenna provides good results over the entire frequency range of the transceiver.

However, for enhanced reception on certain non-Amateur frequencies, you may wish to connect an antenna designed specifically for that frequency range, as the supplied antenna is necessarily a compromise outside the Amateur band, and cannot be expected to provide high performance at all frequencies.

To install the supplied antenna, hold the bottom end of the antenna, then screw it onto the mating connector on the trans- ceiver until it is snug.

Do not over-tighten by use of extreme force. When installing the supplied antenna, never hold the upper part of the antenna while screwing it onto the mating connector on the transceiver. If using an external antenna for transmission, ensure that the SWR presented to the transceiver is 1. Under normal use, the FNB may be used for approximately charge cycles, after which operating time may be expected to decrease.

If you have an old battery pack which is displaying capacity which has become diminished, you should replace the pack with a new one. To remove the battery, turn the radio off and. A fully-discharged pack will be charged completely in 10 hours. The NC is not designed to power the transceiver for operation reception or transmission.

Do not leave the NC connected to the transceiver for continuous periods in excess of 24 hours. Long term overcharging can degrade the Ni-MH battery pack and significantly shorten its useful life.

Please be advised that the NC may contribute noise to TV and radio reception in the immediate vicinity, so we do not recommend its use adjacent to such devices. As your battery discharges during use, the voltage will gradually become lower. When the battery voltage is becoming too low for reliable operation,. Connect the hanger to the rear of the VX, with the notch pointing directly up, using the supplied screw Figure 1.

Use only the screw included with the clip to mount the clip to the back of the VX Always replace all six batteries at the same time, paying attention to the polarity indicated inside the case. The FBAA must not be used with rechargeable cells. Note that the power output and battery life will be much shorter when using Alkaline AA cells.

They should be considered an emergency backup power source only, for this reason. You may also build your own cable, using a fourconductor miniature phone plug, per the diagram below. Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent voltage spikes from possibly damaging your transceiver. See page 62 for details regarding Battery Saver setup. Be sure the Battery Pack is installed, and that the battery is fully charged. The current DC supply voltage will be indicated on the display for 2 seconds.

After this 2 second interval, the display will resume its normal indication of the operating frequency. Clockwise rotation increases. Do not use a higher setting than necessary, or sensitivity to weak incoming signals will be degraded. This feature allows you to set the squelch so that only signals exceeding a certain S-meter. This feature will keep your radio quiet until a call is received from a station sending a carrier which contains a matching subaudible CTCSS tone.

Or, if your friends have radios equipped with DCS Digital Coded Squelch like your VX has, try using that mode for silent monitoring of busy channels. VXL Service manual. VXU Service manual.

These may be changed by the user, if you wish to assign another Set Mode Item to either or both of these keys. Page Dcs Code Inversion 4. Page Reset Procedures 4. Press the [ F ] key momentarily to complete the reset procedure. See page 34 for details regarding the memory Only mode, and the next section regarding Cloning.

This can be particularly useful when configuring a number of transceivers for a public service opera- tion. Page 71 VX O It may be used for configuration of a wide variety of transceiver param- eters, some of which have not been detailed previously. Use the following procedure to activate the Set Mode: 1. Page 73 56 [ PAG. ON INT. KEY: The beeper sounds when you press any key. OFF: Beeper is disabled. Page 78 When the radio is set to the EMG.

Page 80 BUSY: The scanner will hold until the signal disappears, then will resume when the car- rier drops. HOLD: The scanner will stop when a signal is received, and will not restart. TIME: The scanner will hold for the five seconds, then resume whether or not the other station is still transmitting. Select the desired operating mode from the selections shown above.
