To install the battery, hold the transceiver with your left hand, so your palm is over the speaker and your thumb is on the top of the belt clip. Insert the battery pack into the battery compartment on the back of the radio while tilting the Belt Clip outward, then close the Battery Pack Latch until it locks in place with a “Click.”
To remove the battery, turn the radio off and remove any protective cases. Open the Battery Pack latch on the bottom of the radio, then slide the battery downward and out from the radio while unfolding the Belt Clip. Caution!: Do not attempt to open any of the rechargeable Ni-Cd packs, as they could explode if accidentally short-circuited. Low Battery Indication
As the battery discharges during use, the voltage gradually becomes lower. When the battery voltage reaches 6.0 volts, substitute a freshly charged battery and recharge the depleted pack. The TX/BUSY indicator on the top of the radio will blink red when the battery voltage is low.
Avoid recharging Ni-Cd batteries often with little use between charges, as this can degrade the charge capacity. We recommend that you carry an extra, fully-charged pack with you so the operational battery may be used until depletion (this “deep cycling” technique promotes better long-term battery capacity). 3,Operation Preliminary Steps
Install a charged battery pack onto the transceiver, as described previously.
Screw the supplied antenna onto the Antenna jack. Never attempt to operate this transceiver without an antenna connected.
If you have a Speaker/Microphone, we recommend that it not be connected until you are YAESU MUSEN CO., LTD. FCC ID: K66VX-800U EXHIBIT # 11A VX-800U@Operating Manual 2 familiar with the basic operation of the VX-800. Operation Quick Start

VX-800U Circuit Description YAESU MUSEN Co., Ltd. 1/4 VX-800U Circuit Description 1. Overview The VX-800U is a UHF/FM hand-held transceiver designed to operate in the frequency range of 400 to 512MHz. 2. Circuit Configuration by Frequency The receiver is a double-conversion superheterodyne with a first intermediate frequency@(IF) of 44.25MHz and a second IF of 450kHz. Incoming signals from the antenna are mixed with the local signal from PLL to produce the first IF of 44.25MHz. This is then mixed with the 43.8MHz second local oscillator (using the 14.6MHz reference crystal) output to produce the 450kHz second IF. This is detected to give the demodulated signal. The transmit signal frequency is generated by PLL VCO, and modulated by the signal from the microphone. It is then amplified and sent to the antenna. 3. Receive Signal Path 3-1 Front-end RF amplifier Incoming RF from the antenna jack is delivered to the RF Unit and passes through a low- pass filter and high-pass filter consisting of coils L1004, L1005, L1006, L1030, L1001, L1028, L1029, L1002 & L1003, capacitors C1013, C1014, C1015, C1017, C1019, C1020, C1282, C1001, C1005, C1006, C1283, C1007, C1008, & C1009 and antenna switching diode D1020 (HSU277). Signals within the frequency range of the transceiver are then amplified by Q1001 (2SC4227-R34) and enter a varactor-tuned band-pass filter consisting of coils L1008, L1010 & L1011, capacitors C1041, C1042, C1044, C1045, C1046, C1047, C1068, C1069, C1070, C1071, C1072, C1073, C1074 & C1174 and diodes D1018, D1023 & D1024 (all HVC350) before first mixer. 3-2 First Mixer Buffered output from the VCO is amplified by Q1030 (2SC5226-4/5) to provide a pure first local signal between 355.75 and 467MHz for injection to the first mixer D1030 (GN2011- Q). The 44.25MHz first mixer product then passes through monolithic crystal filters XF1001, XF1002 (44-11BF-P2, +/- 5.5 kHz BW) to strip away all but the desired signal. 3-3 IF amplifier The first IF signal is amplified by Q1037 (2SC4215Y). The amplified first IF signal is applied to FM IF subsystem IC Q1046 (BA4116FV) which contains the second mixer, second local oscillator, limiter amplifier, noise amplifier, and S- meter amplifier. A second local signal is generated by Q1022 (2SC4617) using the 14.6MHz crystal X1002 as a reference, producing a 43.8MHz signal which yields a 450kHz second IF when mixed with the first IF signal within Q1046. The second IF then passes through the ceramic filter CF1001 (PBFC450R15D), CF1002 (SFPC450G: only Narrow Channel) to strip away unwanted mixer products, and is applied to the limiter amplifier in Q1046, which removes amplitude variations in the 450kHz IF, before detection of the speech by the ceramic discriminator CD1001 (CDBC450CX24). 3-4 Audio amplifier Detected audio from Q1046 is applied to Q1028 (AK2345) and audio low-pass filter, and then past the volume control (Q1025: M62364FP) to the audio amplifier Q1017 (TDA2822D; external speaker) or Q1063 (TDA2822D; internal speaker), providing up to 0.5 Watts to the optional headphone jack or 16-ohm loudspeaker. Attention: Audio output is BTL output. YAESU MUSEN CO., LTD. FCC ID: K66VX-800U EXHIBIT # 12A VX-800U Circuit Description YAESU MUSEN Co., Ltd. 2/4 3-5 Squelch Control The squelch circuitry consists of a noise amplifier & band-pass filter within Q1046, and noise detector D1053 (DA221). When no carrier received, noise at the output of the detector stage in Q1046 is amplified and band-pass filtered by the noise amplifier section of Q1046 and the network between pins 7 and 8, and then rectified by D1053. The resulting DC squelch control voltage is passed to pin 19 of the microprocessor Q1048. If no carrier is received, this signal causes pin 32 of Q1048 to go low and pin 89 to go high. Pin 32 signals Q1008 (CPH6102), Q1064 (2SA1774-R) and Q1065 (2SA1774-R) to disable the supply voltage to the audio amplifier Q1017 and Q1063, while pin 89 makes Q1014 (UMA2N) hold the green (Busy) half of the LED off, when pin 32 is low and pin 89 is high. Thus, the microprocessor blocks output from the audio amplifier, and silences the receiver while no signal is being received, and during transmission. When a carrier appears at the discriminator, noise is removed from the output, causing pin 19 of Q1048 to go low and the microprocessor to blink the busy LED via Q1048. The microprocessor then checks the DTMF decoder chip on the Optional Unit, the CTCSS and the CDCSS code for DTMF or CTCSS or CDCSS code squelch information, if enabled, respectively. If not transmitting and CTCSS or CDCSS is not activated, or if the received tone or code matches that programmed, the microprocessor stops scanning, if active, and allows audio to pass through the audio amplifier Q1017, Q1063 (TDA2822D) to the loudspeaker by enabling the supply voltage to it via Q1008, Q1064 and Q1065. 4. Transmit Signal Path 4-1 Microphone amplifier Speech input from the microphone is amplified in Q1022 (BA10324AFV) after there is a filter and is sent to Q1025 (M62364FP) and sent to Dummy Unit (or Optional Unit). The audio, which returned from Dummy Unit, passes Q1028 (AK2345) to be pre-emphasized. The processed audio is then mixed with a CTCSS tone generated by Q1028 (AK2345) and delivered to D1035 (HVC350) for frequency modulating the PLL carrier up to +/- 5kHz from the unmodulated carrier at the transmitting frequency. If an external microphone is used, PTT switching is controlled by Q1007 (UMZ2N), which signals the microprocessor when the impedance at the microphone jack drops. If a CDCSS code is enabled for transmission, the code is generated by microprocessor Q1048 and delivered to D1055 (HVC350) for CDCSS modulating. If DTMF is enabled for transmission, the tone is generated by the microprocessor Q1048 and applied to the splutter filter section in place of speech audio. Also, the tone is amplified for monitoring in the loudspeaker. 4-2 Noise canceling microphone circuit The two signals from internal micr…

VX-800U Alignment YAESU MUSEM Co., Ltd. 1/6 VX-800U Alignment Introduction The VX-800 is carefully aligned at the factory for the specified performance across the frequency range specified for each version. Realignment should therefore not be necessary except in the event of a component failure, or altering version type. All component replacement and service should be performed only by an authorized YAESU representative, or the warranty policy may be void. The following procedures cover the sometimes critical and tedious adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts subsequently are placed, realignment may be required. If a sudden problem occurs during normal operation, it is likely due to component failure; realignment should not be done until after the faulty component has been replaced. We recommend that servicing be performed only by authorized YAESU service technicians who are experienced with the circuitry and fully equipped for repair and alignment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized YAESU service technicians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty components. Those who do undertake any of the following alignments are cautioned to proceed at their own risk. Problems caused by unauthorized attempts at realignment are not covered by the warranty policy. Also, YAESU reserves the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function and operation of the transceiver are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and realignment determined to be absolutely necessary. The following test equipment (and thorough familiarity with its correct use) is necessary for complete realignment. Correction of problems caused by misalignment resulting from use of improper test equipment is not covered under the warranty policy. While most steps do not require all of the equipment listed, the interactions of some adjustments may require that more complex adjustments be performed afterwards. Do not attempt to perform only a single step unless it is clearly isolated electrically from all other steps. Have all test equipment ready before beginning, and follow all of the steps in a section in the order presented. Required Test Equipment

YAESU CT-71 Connection Cable & Alignment program Alignment Preparation & Precautions A 50-Ω RF Dummy Load and in-line wattmeter must be connected to the main antenna jack in all procedures that call for transmission, except where specified otherwise. Correct alignment is not possible with an antenna. After completing one step, read the following step to determine whether the same test equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, in connected) before proceeding. Correct alignment requires that the ambient temperature be the same as that of the transceiver and test equipment, and that this temperature be held constant between 20 and 30 °C (68 ∼ 86 °F). When the transceiver is brought into the shop from hot or cold air, it should be allowed time to come to room temperature before alignment. Whenever possible, alignments should be made with oscillator shields and circuit boards firmly affixed in place. Also, the test equipment must be thoroughly warmed up before beginning. Note: Signal levels in dB referred to in the alignment procedure are based on 0dB μ EMF = 1μV. Setup the test equipment as shown for transceiver alignment, apply 7.5V DC power to the transceiver. Refer to the drawings above for Alignment Points.
