The information presented here will allow you to derive maximum performance from your radio. After reading it, keep the manual handy for quick reference, in case questions arise later on. We're glad you joined the Yaesu team. Call on us any time, because our business is communications. Let us help you get your message across. NOTICE There are no user-serviceable points this transceiver. All service jobs must be referred to your Authorized Service Center or Network Administrator. Features The VX-4000 Series are rugged basic-featured FM transceivers designed for flexible mobile and base station business communications in the 50-watts VHF and 40-
watts UHF A highly integrated surface mount circuit design and a die-cast aluminum chassis assure reliability. Selectable power output of LOW(5 25 watts) or High (VHF:50watts, UHF:40watts) without the need of forced air cooling is possible due to the large heatsink surface area of the compartmentalized one-piece diecast chassis. The 250-channels memories can each be programmed with a 8-character channel name. A 39-tone programmable CTCSS encoder/decoder is built in as standard. inside flash memory on A 104 standerd digital codes programmable DCS encoder/decoder is built in as standard. Important channel frequency data is stored in EEPROM and is easily programmable by dealers using a personal computer and the Yaesu CT-71 Programming Cable and CE-35 Software. the CPU, and Front panel 1 2 3 4 5 6 7 8 9 10 11 12 13 14 CONTROL & CONNECTORS 1 TX Indicator This lamp glows red when the radio is transmitting. 2 POWER Button Turn the radio on or off.
(Press and hold in this button for 1.5 second.) 3 BUSY Indicator This lamp glows green when the channel is busy. 4 Liquid Crystal Display The display include an 8-character alpha-numeric section showing channel and group names, status and identity information, and error messages. Additional indicators on the display show priority channel assignments and scan include / exclude selection. 5 UP Pressing this button changes the current group (and displayed group number or name). Holding this button for more than 1/2 second causes the function to repeat. 6 DOWN Pressing this button changes the current group (and displayed group number or name). Holding this button for more than 1/2 second causes the function to repeat. 7 Programmable Function Button This button can be set up for special applications, such as high/low power selection, monitor, dimmer, talk-
around, and call alert function, as determined by your network requirements and programmed by your Yaesu dealer. The default function is set as Dimmer Button. 8 HOME Indicator This lamp glows orange when incorrect position at the setting of CE-35. 9 VOLUME Knob This knob adjusts the receiver volume. 10 CHANNEL Selector Knob This knob select the operating channel. 11 Programmable Function Button The default function is set as MONI Button. 12 Programmable Function Button The default function is set as Low Power Button. 13 Programmable Function Button The default function is set as no function Button. 14 Programmable Function Button The default function is set as no function Button. Rear 15 16 18 18 15 Antenna Socket The 50-ohm coaxial feedline to the antenna must be connected here using a type-M (PL-259) plug. 16 EXT SP (External Speaker) An external loudspeaker may be connected to this 2-
contact, 3.5-mm mini-phone jack. Caution: Do not connect this line to ground, and be certain that the speaker has adequate capability to handle the audio output from the radio. 17 13.8V DC Cable w/Connector The supplied DC power cable must be connected to this 2-pin connector. Use only the supplied fused cable, extended if necessary, for power connection. 18 DSUB 25-Pin Accessory Connector External TX audio line input, PTT, Squelch, and external RX audio line output signal may be obtained from this connector for use with accessories such as data transmission/reception modems, ets. Side 19 19 Microphone Jack Connect the microphone plug to this jack. Basic Operation of the Transceiver Important! Before turning on the radio the first time, confirm that the power connections have been made correctly and that a proper antenna is connected to the antenna jack. Push the POWER switch turn on the radio. The display will become illuminated. The radio will start up on the last channel used prior to shutdown during the previous operating session. Transmitting To transmit, wait until the BUSY indicator is off (the channel is not in use), and press the PTT (Push-To-Talk) switch on the side of the microphone (the TX lamp will glow red). While holding in the PTT switch, speak across the face of the microphone in a clear, normal voice level, and then release the PTT switch to receive. Automatic Time-Out Timer If the selected channel has been programmed for automatic time-out, you must limit the length of each transmission. While transmitting, a beep will sound five seconds before time-out. Another beep will sound just before the deadline; the TX indicator will disappear and transmission will cease soon thereafter. To resume transmitting, you must release the PTT and wait for the penalty timer to expire (if you press the PTT before this timer expires, the timer restarts, and you will have to wait another penalty period). Scanning Operation With the microphone in its hanger, press the SCAN button momentarily to activate scanning. Typically, DSC will initially appear on the display, indicating Dealer Channel Scan as the scanning mode. If you wish to change to one of the modes described in the list above, press the SEL button repeatedly until that mode appears on the display. If you pick up the microphone while no signal is being received, operation will shift to a particular channel. Which channel that will be depends on which of the following options the dealer has programmed for off-hook channel selection:
Scan Start Channel Lifting the microphone causes operation to revert to the group and channel last selected before scanning started or resumed. Priority Revert Lifting the microphone activates the Priority 1 channel in the current group. If no channel is assigned level 1 priority, operation will be on the Priority 2 channel. If no priority channels have been assigned, operation reverts to the Scan Start Channel. Last Busy Lifting the microphone causes operation to revert to the group and channel where activity was last detected. If no activity was detected since turning on the radio, operation reverts to the Scan Start Channel. Voting scan The radio can be programmed for Voting Scan, whereby the radio will lock onto the strongest signal in a pre-
programmed set of channels. The radio is used as normal, with the exception that transmission is not allowed when the unit is out of range of the nearest repeater. Consult your Yaesu dealer for more information regarding this function. Programmable Function Button Low Power With this feature enable, a button toggles between high and low transmitter power, as programmed by the dealer. MONI This function is monitoring for the current channel. SCN This function is start and stop the scanning. HA Horn Alert function On and Off. Call/Reset When this feature is programmed and a selective call has been received, momentarily press the button to reset the flashing indicator and mute the receiver, otherwise press the button to sent your radios identification code
(ANI) to the dispatcher. Talk Around The feature causes a button to select simplex operation on semi-duplex channels:
frequency becomes the same as the receive frequency (regardless of any programmed offset for the channel). Note: This feature has no effect on simplex channels. After pressing the button, TA is displayed on LCD. Encryption When the Voice Scrambler feature is enabled, pressing a button toggles the Scrambler on and off. Alarm Function When the alarm function is enabled, pressing a button causes the radio to revert to a specially designated channel, and causes the special alarm identifier code to be transmitted automatically. Note: This feature is only available as a Secondary accessory to prevent accidental activation. Fuse Replacement transmit the If a fuse is blown, before replacing, see if you can determine if it was caused by something outside of the radio (perhaps a short circuit due to a worn cable or pigtail near the radio). Contact your Ysesu dealer at once if you do not find the cause. Replace fuses only with the same type installed. This is device complies with Part 15 of the FCC rules. Operation is subject to the condition that this device does not cause harmful interference. Specifications General Frequency Range:
