VX-520U OPERATING MANUAL VX-520U UHF Hand-Held Portable Land Mobile Transceiver The VX-520U is a frequency-synthesized, microprocessor-controlled FM hand-held portable transceiver providing up to five watts of power output on up to 32 channels in the UHF Land Mobile Band. Designed specifically for commercial and professional applications, the VX-520U is housed in highstrength die-cast aluminum alloy, sealed to MIL-810 C, D & E intrinsically safe (I/S) and weather-tight specifications.
VX-520U OPERATING MANUAL CONTROLS & CONNECTORS Top panel À VOL Control This control adjusts the volume of the receiver, and turns the radio off when rotated fully counterclockwise to the click-stop Á S/DW Button (Scan/Dual Watch) Pressing and holding this button more than 2 seconds (but less than 4 seconds) turns the channel scanner on and off. Pressing and holding this button more than 4 seconds activates the Dual Watch feature (explained later).
VX-520U OPERATING MANUAL CONTROLS & CONNECTORS Ä BUSY/TX Indicator This lamp blinks green when a signal is being received (or the squelch is opened by pressing the MON RES button) and red when transmitting. To avoid interference, do not transmit if the lamp is glowing green. When the battery almost depleted, this lamp blinks red, indicating that the battery needs recharging or replacement very soon. Å CH Rotary Selector This rotary switch selects the operating channel.
VX-520U OPERATING MANUAL CONTROLS & CONNECTORS Side Panel Buttons À MON RES (Monitor/Reset) Button Pressing and holding this button more than 2 seconds (but less than 4 seconds) disables the tone squelch, and permits monitoring of stations transmitting on the selected channel while still keeping your receiver quiet from noise (“MO” will appear at the top right of the LCD). Press it again to only hear calls within your network.
VX-520U OPERATING MANUAL CONTROLS & CONNECTORS Á PTT (Push-To-Talk) button Hold this button to transmit (the “BUSY/TX” indicator glows red). Â LAMP/LOCK button Press this button momentarily to illuminate the display for five seconds. Pressing and holding this button locks top-panel push-buttons (S/DW, DISP, and the optional DTMF keypad); this can be enabled to prevent radio settings from being disturbed.
VX-520U OPERATING MANUAL OPERATION Preliminaries If the transceiver has not been used since leaving the factory, fully charge the battery using VAC-520 Rapid Desktop Charger before using it. Mount the battery on the transceiver as described and shown in the illustration below. Also, install the antenna on the jack on top of the transceiver by screwing the connector into the jack until it is finger-tight.
VX-520U OPERATING MANUAL OPERATION Preliminary Steps Before operating the transceiver for the first time: ¦ Charge the battery pack and connect the supplied helical rubber flex antenna to the antenna jack on the top of the transceiver. Never operate the transceiver without an antenna connected. ¦ If you have a Speaker/Mic, we suggest you do not connect it until you are familiar with basic operation.
VX-520U OPERATING MANUAL OPERATION An important note about your radio ! Some of the radio/button functions discussed next will only operate in your radio if so programmed by your dealer, or after the installation of certain internal optional units. In this way, the radio’s operation can be simplified and customized specifically for the user according to network requirements.
VX-520U OPERATING MANUAL OPERATION pear briefly. Use the CH knob to select a channel, then press the S/DW button to enable the channel for scanning (“E” will appear in the upper left corner of the LCD). Repeat this process for each channel you want the scanner to check. To remove a channel from those to be scanned, press S/DW again, so that “E” no longer appears in the display. After you have enabled all the channels you want to scan, turn the radio off, then on again to return to normal operation.
VX-520U OPERATING MANUAL OPERATION Priority Scanning Priority scanning allows you to scan and monitor channels while the receiver periodically checks for calls on a pre-selected (“priority”) channel. You may want to use this feature if you want to scan different channels, but don’t want to miss a call for you on a primary dispatch, emergency or tactical frequency. After a call has been received on the priority channel, operation returns to the programmed default channel scheme, as mentioned before.
VX-520U OPERATING MANUAL OPERATION Dual Watch If you need to operate on a non-priority channel while still checking for calls on the priority channel, the Dual Watch feature let’s you to do this without using the scanner. When enabled, operation on any selected nonpriority remains normal as before, however, when a signal is received on the priority channel or when you press the PTT switch, operation immediately shifts to the priority channel.
VX-520U OPERATING MANUAL PRE-PROGRAMMED FUNCTIONS The function selected by pressing and holding the DISP button more than 2 seconds (but less than 4 seconds) can be customized by dealer programming and your network requirements. A brief explanation of available functions is provided below. However, contact your dealer for details on their use and operation.
VX-520U OPERATING MANUAL BUTTON FUNCTIONS As mentioned before, button functions can be customized by programming from your Vertex Standard dealer to meet your communications/ network requirements. Some features may require the purchase and installation of optional internal accessories for operation. The table below illustrates the possible Top-panel button programming combinations. Functions are explained on the previous page “PRE-PROGRAMMED FUNCTIONS.
VX-520U OPERATING MANUAL CUSTOM SETTINGS Below is a table of radio features that can be customized by dealer programming. To change a feature as your requirements change, contact your Vertex Standard dealer. For future reference, check the box next to the option that has been programmed in your particular radio, and keep it handy. Feature Explanation r Enabled r Disabled Channel scanning can be disabled completely for systems not requiring this feature.
VX-520U OPERATING MANUAL INSTALLING CHANNEL-STOPS To simplify operation and prevent selection of unprogrammed/unused channels or channel groups, tiny metal inserts or “stops” can be inserted into the top panel beneath the CH selector knob. A tiny tab protruding from beneath the skirt of the CH knob engages the stop(s) as it is turned, preventing further rotation.
VX-520U OPERATING MANUAL UNDERSTANDING RADIO WAVES Radio waves travel from one point to another by several different means. The general term for these methods of wave travel is “propagation”. You may know that “shortwave” signals can be propagated over distances of several thousand miles by reflection off of the upper regions of the atmosphere. Your hand-held transceiver, on the other hand, operates on the so-called UHF (Ultra-High Frequency) band.
