Some accessories are supplied as standard per local requirements, while others may be unavailable in some regions. Consult your Yaesu Dealer for details regarding these and any newly-available options. Connection of any non-Yaesu-approved accessory, should it cause damage, may void the Limited Warranty on this apparatus. Installation of Accessories Antenna Installation The supplied antenna provides good results over the entire frequency range of the transceiver. However, for enhanced base station medium-wave and shortwave reception, you may wish to connect an external (outside) antenna. The supplied antenna consists of two sections: the Base Antenna (used for operation above 50 MHz), and the Extender Element (used for monitoring of frequencies below 50 MHz). To Install the Supplied Antenna Hold the bottom end of the antenna, then screw it onto the mating connector on the transceiver until it is snug. Do not over-tighten by use of extreme force. When operating the VX-8R on the 50 MHz band and lower frequencies, disconnect the antenna cap from the base antenna, then screw the Extender Element onto the Antenna Base. Of course, the VX-8R may be operated on frequencies higher than the 50 MHz band while the Extender Element is still attached onto the Antenna Base. Notes:

Never transmit without having an antenna connected. 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 1.5:1 or lower. Take care not lose the antenna cap when removing it from the Base Antenna. Installation of FNB-101LI Battery Pack The FNB-101LI is a high-performance Lithium-Ion battery providing high capacity in a very compact package. Under normal use, the FNB-101LI may be used for approximately 300 charge cycles, after which operating time may be expected to decrease. If you have an old Vertex Standard Co.,Ltd. 7 FCC ID: K6620295X20 IC :511B-20295X20 Operating Manual Install the FNB-101LI as shown in the illustration. battery pack which is displaying capacity which has become diminished, you should replace the pack with a new one. 1. 2. Close the Battery Pack Latch on the bottom of the radio. If the battery has never been used, or its charge is depleted, it may be charged by connecting the NC-86B/C Battery Charger, as shown in the illustration, to the EXT DC jack. If only 12 ~ 16 Volt DC power is available, the optional E-DC-5B or E-DC-6 DC Adapter (with its cigarette lighter plug) may also be used for charging the battery, as shown in the illustration. While the battery is being charged, the display will indicate CHARGING and the key will glow red. The S-meter will deflect according to the charging status. When charging is finished, the display will change to indicate COMPLETE and the key will glow green. Installation of FBA-39 Alkaline Battery Case (Option) The optional FBA-39 Battery Case allows receive monitoring using three AA size Alkaline batteries. Alkaline batteries can also be used for transmission in an emergency, but power output will only be selectable 1 W and 50 mW. To Install Alkaline Batteries into the FBA-39 1. Slide the batteries into the FBA-39 as shown in the illustration, with the Negative []

side of the batteries touching the spring connections inside the FBA-39. 2. Open the Battery Pack Latch on the bottom of the radio. 3. Install the FBA-39 as shown in the illustration, with the [+] side facing the bottom of the transceiver. 4. Close the Battery Pack Latch on the bottom of the radio. The FBA-39 does not provide connections for charging, since Alkaline cells cannot be re-charged. Therefore, the NC-86B/C, E-DC-5B, or E-DC-6 may safely be connected to the EXT DC jack when the FBA-39 is installed. Notes:

The FBA-39 is designed for use only with AA-type Alkaline cells. If you do not use the VX-8R for a long time, remove the Alkaline batteries from the FBA-39, as battery leakage could cause damage to the FBA-39 and/or the transceiver. Battery Life Information When the battery charge is almost depleted, a Low Voltage indicator will appear on the display. When this icon appears, it is recommended that you charge the battery soon.

(1) TX 6 sec., RX 6 sec. and Squelched 48 sec.

(2) Continuous signal reception The current battery voltage can be displayed manually on the LCD, by following the instructions on page ??. Battery capacity may be reduced during extremely cold weather operation. Keeping the radio inside your parka may help preserve the full charge capacity. AC Operation Using NC-86B/C (Receiving only) The VX-8R may be operated from your house current by use of the supplied NC-86B/C Battery Charger. The NC-86B/C should only be used for reception, because it is not capable of supplying sufficient current to support transmission. To use the NC-86B/C, turn the transceiver off, then plug the miniature connector of the Battery Charger into the EXT DC jack on the side of the radio. Now plug the Battery Charger into the wall outlet. You may now turn on the transceiver. Interface of Packet TNC The VX-8R may be used for Packet operation, using the optional CT-131 microphone adapter (availablefrom your Yaesu dealer) for easy interconnection to commonly-available connectors wired to your TNC. You may also build your own cable using a four-conductor miniature phone plug, per the diagram below. The audio level from the receiver to the TNC may be adjusted by using the VOLUME knob, as with voice operation. The input level to the VX-8R from the TNC should be adjusted at the TNC side; the optimum input voltage is approximately 5 mV at 2000 Ohms. Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent voltage spikes from possibly damaging your transceiver. Operation Note: Hi! Im R. F. Radio, and Ill be helping you along as you learn the many features of the VX-8R. I know youre anxious to get on the air, but I encourage you to read the Operation section of this manual as thoroughly as possible, so youll get the most out of this fantastic new transceiver. Now, lets get operating!

Switching Power On and Off 1. Be sure the battery pack is installed, and that the battery is fully charged. Connect the Vertex Standard Co.,Ltd. 9 FCC ID: K6620295X20 IC :511B-20295X20 Operating Manual antenna to the top panel ANTENNA jack. 2. Press and hold in the [PWR] switch (on the right side of the front panel) for 2 seconds. Two beeps will be heard when the switch has been held long enough, and the opening message will appear on the display, then frequency display will appear. After another two seconds, the receive-mode Battery Saver function will become active, unless you have disabled it (see page ??). 3. To turn the VX-8R off, press and hold in the [PWR] switch again for 2 seconds. Note: If you dont hear the two Beep tones when the radio comes on, the Beeper may have been disabled via the Menu system. See page ??, which tells you how to reactivate the Beeper. Adjusting the Volume Level Rotate the DIAL knob while pressing and holding the [VOL] key to set the desired audio level. Clockwise rotation increases the volume level. The Volume level may be set on the Main and Sub bands separately. Squelch Adjustment The VX-8Rs Squelch system allows you to mute the background noise when no signal is being received. Not only does the Squelch system make standby operation more pleasant, it also significantly reduces battery current consumption. The Squelch system may be adjusted independently for the FM and Wide-FM (FM Broadcast) modes. 1. Press the [F/W] key, then press the [MONI/T-CALL] key on the left side of the radio. This provides a Short-cut to Menu Item 96: SQL LEVEL. 2. Now, rotate the DIAL knob to set the background noise is just silenced (typically at a setting of about 3 or 4 on the scale); this is point of maximum sensitivity to weak signals. 3. When you are satisfied with the Squelch threshold setting, press the PTT key momentarily to save the new setting and exit to normal operation. 4. You may also adjust the Squelch setting by using the Set (Menu) mode. See page ??

for details. Note 1: The Squelch level may be set on the Main and Sub bands separately. Note 2: If youre operating in an area of high RF pollution, you may need to consider Tone Squelch operation using the built-in CTCSS Decoder. This feature will keep your radio quiet until a call is received from a station sending a carrier which contains a matching Vertex Standard Co.,Ltd. 10 FCC ID: K6620295X20 IC :511B-20295X20 Operating Manual

(subaudible) CTCSS tone. Or if your friends have radios equipped with DCS (Digital Coded Squelch) like your VX-8R has, try using that mode for silent monitoring of busy channels. Selecting the Operating Band In the factory default configuration, the VX-8R operates in the Dual Receive mode. During Dual Receive operation, the VFO-A frequency will be displayed on the upper side of the LCD, and the VFO-B frequency will be displayed on the lower side, with the Operating band (the band on which transmission and band/frequency change are possible) being indicated in large characters, and Receive only band being indicated in small characters. To switch the Operating band: press the [A] key momentarily to engage the VFO-A frequency as the Operating band. Alternatively, press the [B] key momentarily to engage the Sub band frequency as the Operating band, described previously. Press and hold in the [A] or [B] key for 1/2 seconds to switch to Mono Band Operation with a double-size display. During Mono band operation, you may press the [F/W] key, then press the [A]/[B] key, to change the display to show only large characters. Selecting the Frequency Band The VX-8R covers an incredibly wide frequency range, over which a number of different operating modes are used. Therefore, the VX-8Rs frequency coverage has been divided into different operating bands, each of which has its own pre-set channel steps and operating modes. You can change the channel steps and operating modes later, if you like

(see page ??). To Change Operating Bands 1. Press the [BAND] key repetitively. You will see the LCD indication move toward a higher frequency band each time you press the [BAND] key. Indicates a Band Number according to the receiving frequency on the display. If you wish to move the operating band selection downward (toward lower frequencies), press the [F/W] key first, then press the [BAND] key. 2. 3. The VX-8R uses a dual VFO system (described previously). To switch TX/RX operation from the VFO-A to the VFO-B instantly, press the [B] key momentarily. Pressing the

[A] key will return the VX-8R to the VFO-A. The frequency band bearing the Large characters is the band on which transmission is possible; the band designated by Vertex Standard Co.,Ltd. 11 FCC ID: K6620295X20 IC :511B-20295X20 Operating Manual Small characters may only be used for reception. 4. Once you have selected the desired band, you may initiate manual tuning (or scanning) per the discussions on the next page. Note 1: The SW Band and Information Band reception is only possible on the VFO-A. Note 2: The VX-8R has an AM/FM Broadband radio. You can receive these bands independently. See page ?? for details. Note 3: If desired, you may omit (skip) one or more bands from the band selection loop for faster recall of your favorite operating bands. See page ?? for details. Frequency Navigation The VX-8R will initially be operating in the VFO mode, as just described. This is a channelized system which allows free tuning throughout the currently-selected operating band. Three basic frequency navigation methods are available on the VX-8R:

1) Tuning Dial Rotation of the DIAL knob allows tuning in the pre-programmed steps established for the current operating band. Clockwise rotation of the DIAL knob causes the VX-8R to be tuned toward a higher frequency, while counter-clockwise rotation will lower the operating frequency. If you press the [F/W] key momentarily, then rotate the DIAL knob, frequency steps of 1 MHz will be selected. This feature is extremely useful for making rapid frequency excursions over the wide tuning range of the VX-8R. 2) Direct Keypad Frequency Entry The desired operating frequency may be entered directly from the keypad. The operating mode will automatically be set once the new frequency is entered via the keypad. To enter a frequency from the keypad, just press the numbered digits on the keypad in the proper sequence. There is no Decimal point key on the VX-8R, so if the frequency is below 100 MHz (e.g. 15.150 MHz), any required leading zeroes must be entered. However, there is a short-cut for frequencies ending in zero - press the [V/M] key after the last non-zero digit. Examples:

To enter 146.520 MHz, press [1] [4] [6] [5] [2] [0]

To enter 15.255 MHz, press [0] [1] [5] [2] [5] [5]

To enter 1.250 MHz (1250 kHz), press [0] [0] [1] [2] [5] [0]

To enter 0.950 MHz (950 kHz), press [0] [0] [0] [9] [5] [0]

To enter 430.000MHz, press [4] [3] [V/M]

Vertex Standard Co.,Ltd. 12 FCC ID: K6620295X20 IC :511B-20295X20 Operating Manual 3) Scanning From the VFO mode, press and hold in either the [UP] or [DOWN] key for one second to initiate upward or downward scanning, respectively, and will stop when it receives a signal strong enough to break through the Squelch threshold. The VX-8R will then hold on that frequency according to the setting of the RESUME mode (Menu Item 89: SCAN RESUME). See page ?? for details. If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of a higher frequency), just rotate the DIAL knob one click in the counter-clockwise direction while the VX-8R is scanning. The scanning direction will be reversed. To revert to scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise. Press the PTT switch momentarily to cancel the scanning. Transmission Once you have set up an appropriate frequency inside one of the three (or four) Amateur bands on which the VX-8R can transmit (50 MHz, 144 MHz, or 430 MHz, plus 222 MHz on the USA version), youre ready to transmit. These are the most basic steps; more advanced aspects of transmitter operation will be discussed later. 1. To transmit, press the PTT switch, and speak into the front panel microphone (located in the upper right-hand corner of the speaker grille) in a normal voice level. The LED of the

[A] or [B] which is designated the Main band will glow red during transmission. 2. To return to the receive mode, release the PTT switch. 3. During transmission, the relative power level will be indicated on the LCD. Additionally, the L1, L2, L3, or HI icon will appear at the left side of the PO meter, corresponding with the Power Level setting. Note 1: If youre just talking to friends in the immediate area, youll get much longer battery life by switching to Low Power operation. To do this, press the [F/W] key, then press the

[Internet] key so that the Low Power icon appears at the bottom of the display. And dont forget: always have an antenna connected when you transmit. Note 2 Transmission is not possible on Sub band and any operating bands other than the 50 MHz, 144 MHz, 222 MHz (USA version), and 430 MHz bands on the Main band. Changing the Transmitter Power Level You can select between a total of four transmitter power levels on your VX-8R. The exact power output will vary somewhat, depending on the voltage supplied to the transceiver. With the standard FNB-101LI Battery Pack and external DC source, the power output levels available are:

Vertex Standard Co.,Ltd. 13 FCC ID: K6620295X20 IC :511B-20295X20 Operating Manual To change the power level:

1. The default setting for the power output is High; in this configuration, the display shows HI icon. Pressing the [F/W] key, followed by the [Internet] key, causes the power level L1, L2, or L3 to appear. 2. Press the [F/W] key, followed by the [Internet] key (repeatedly, if necessary) to make the HI icon appear and restore High Power operation. Note 1: The VX-8R is smart! You can set up Low power on one band (like UHF), while leaving VHF on High power, and the radio will remember the different settings on each band. And when you store memories, you can store High and Low power settings separately in each memory, so you dont waste battery power when using very close-in repeaters!

Note 2: When you are operating on one of the Low power settings, you can press the key, then press the PTT switch, to cause the VX-8R to transmit (temporarily) on High power. After one transmission, the power level will revert to the previously-selected Low power setting. AM and FM Broadcast Reception The VX-8R includes provision for reception of AM and FM broadcasts. FM broadcast reception, utilizes a wide-bandwidth filter and stereo decoder which provides excellent fidelity. 1. Press the [A] key momentarily to engage the VFO-A as the Operating band. 2. Press the [F/W] key, then press the [0(RADIO)] key to enter the Broadcast Reception mode. 3. Press the [BAND(SC-M BND DW)] key to toggle the receiving band between AM broadcast and FM broadcast. The AM broadcast coverage is 510 to 1790 kHz and utilizes AM mode. The Band Number changes to A (which means AM) and an Operating Mode icon changes to AM. The FM broadcast coverage is 76.00 to 107.90 MHz and utilizes Wide-FM mode. The Band Number changes to F (which means FM) and an Operating Mode icon changes to WFM. 4. Rotate the DIAL knob to select the desired station. 5. To exit to normal operation, press the [F/W] key followed by the [0(RADIO)] key.
