Please take a few minutes to read this manual carefully. 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 inside 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 40watts 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.

A 104 standerd digital codes programmable DCS encoder/decoder is built in as standard.

Important channel frequency data is stored in EEPROM and flash memory on the CPU, and is easily programmable by dealers using a personal computer and the Yaesu CT-71 Programming Cable and CE-35 Software.

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.

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
