Insert the battery pack into the battery compartment on the back of the radio while titling the Belt Clip outward. ・ To remove the battery, turn the radio off and remove protective cases. Slide the Battery Pack Latch on the bottom of the radio, and 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 Li-Ion 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 becomes to low, 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 Li-Ion 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) FCC ID: K6610654820 IC ID: 511B-10654820 Operating Manual 2/7 Vertex Standard Co., Ltd.

FCC ID: K6610654820 IC ID: 511B-10654820 Circuit Description 1/3 Vertex Standard Co., Ltd. VX-350 Series Circuit Description 1. Circuit Configuration by Frequency The receiver is a Double-conversion Super-heterodyne with a first intermediate frequency (IF) of 50.85MHz and a second IF of 450kHz. Incoming signal from the antenna is mixed with the local signal from the VCO/PLL to produce the first IF of 50.85MHz. This is then mixed with the 50.4MHz second local oscillator output to produce the 450kHz second IF. This is detected to give the demodulated signal. The transmit signal frequency is generated by the PLL VCO, and modulated by the signal from the microphone. It is then amplified and sent to the antenna. 2. Receiver System 2-1. Front-end RF amplifier Incoming RF signal from the antenna is delivered to the MAIN-3 Unit and passes through Low-pass filer, antenna switching diode, high pass filter and removed undesired frequencies by varactor diode (tuned band-pass filer). The passed signal is amplified in Q3021 and moreover cuts an image frequency with the tuned band pass filter and comes into the 1st mixer. 2-2. First Mixer The 1st mixer consists of the Q3036. Buffered output from the VCO is amplified by Q3031 to provide a pure first local signal between 329.15 and 419.15MHz for injection to the first mixer. The IF signal then passes through monolithic crystal filters XF3001(±5.5 kHz BW) to strip away all but the desired signal. 2-3. IF Amplifier The first IF signal is amplified by Q3048. The amplified first IF signal is applied to FM IF subsystem IC Q3053 which contains the second mixer, second local oscillator, limiter amplifier, noise amplifier, and S-meter amplifier. The signal from reference oscillator X3002 becomes 3 times of frequencies in Q3053, it is mixed with the IF signal and becomes 450KHz. The second IF then passes through the ceramic filter CF3001 (wide channels), CF3002 (narrow channels) to strip away unwanted mixer products, and is applied to the limiter amplifier in Q3053, which removes amplitude variations in the 450kHz IF, before detection of the speech by the ceramic discriminator CD3001. 2-4. Audio amplifier Detected signal from Q3053 is inputted to mute switch Q3001-3 and option switch Q3001-2. The signal which appeared from Q3001-2 is in band pass filter Q3066. In the case an optional unit is installed, the Q3001-2 is made OFF and the AF signal from Q3001-3 goes the optional unit. In the case an optional unit is not installed, Q3001-2 is made ON and the signal goes through Q3001-2. The signal which passed Q3066 goes to AF volume (VR3001). And then the signal goes to audio amplifier Q3007. The output signal from Q3007 is in audio speaker. 2-5. Squelch Circuit There are 16 levels of squelch setting from 0 to 15. The level 0 means open the squelch. The level 1 means the threshold setting level and level 14 means tight squelch. From 2 to 13 is established in the middle of threshold and tight. The bigger figure is nearer the tight setting. The level 15 becomes setting of carrier squelch. 2-5-1. Noise Squelch Noise squelch circuit is composed of the band path filter of Q3053, noise amplifier FCC ID: K6610654820 IC ID: 511B-10654820 Circuit Description 2/3 Vertex Standard Co., Ltd. Q3058, and noise detector D3042, D3043. When a carrier isn't received, the noise ingredient which goes out of the demodulator Q3053 is amplified in Q3058 through the band path filter Q3053, is detected to DC voltage with D3042, D3043 and is inputted to 48pin (the A/D port) of the Q3044 (CPU). When a carrier is received, the DC voltage becomes low because the noise is compressed. When the detected voltage to CPU is high, the CPU stops AF output with Q3001-1 "OFF" by making the 39pin (CPU) "L" level. When the detection voltage is low, the CPU makes Q3001-1 ON with making 39pin "H" and the AF signal is output. 2-5-2. Carrier Squelch The CPU (47pin: A/D port) detects RSSI voltage output from Q3053 12 pin, and controls AF output. The RSSI output voltage changes according to the signal strength of carrier. The stronger signal makes the RSSI voltage to be higher voltage. The process of the AF signal control is same as Noise Squelch The shipping data is adjusted 3dB higher than squelch tight sensitivity. 3. Transmitter System 3-1. Mic Amplifier The AF signal from internal microphone MC3001 or external microphone J3002 is amplified with microphone amplifier Q3069-2, after passes microphone gain volume Q3017. AF signal is passes a pre-emphasis circuit. Q3001-1 becomes OFF when an option unit is attached and the AF signal from Q3068 goes via the option unit. When an option unit isn't attached, Q3001-1 becomes ON, the signal passes Q3001-1 and is input to the limiter amplifier Q3068-2. The signal passed splatter filter of Q3068 and adder amplifier Q3065 is adjusted by maximum deviation adjustment volume Q3017. The AF signal ingredient is amplified Q3065. After that, it is made FM modulation to transmit carrier by the modulator D3023 of VCO. 3-2. Drive and Final amplifier The modulated signal from the VCO Q3049 is buffered by Q3042 and amplified by Q3031. Then the signal is buffered by Q3026 for the final amplifier driver Q3020. The low-level transmit signal is then applied to Q3013 for final amplification up to 5watts output power. The transmit signal then passes through the antenna switch D3002 and is low pass filtered to suppress away harmonic spurious radiation before delivery to the antenna. 3-4. Automatic Transmit Power Control The current detector Q3064-1 detects the current of Q3013 and Q3020, and converts the current difference to the voltage difference. The output from the current detector Q3064-1 is compared with the reference voltage and amplified by the power control amplifier Q3064-2. The output from Q3064-2 controls the gate bias of the final amplifiers Q3013 and the final amplifier driver Q3020. The reference voltage changes into four values (Transmit Power High and Low) controlled by Q3017…

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 Vertex Standard 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 Vertex Standard 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, Vertex Standard 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. FCC ID: K6610654820 IC ID: 511B-10654820 Alignment 2/4 Vertex Standard Co., Ltd.

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. FCC ID: K6610654820 IC ID: 511B-10654820 Alignment 3/4 Vertex Standard Co., Ltd.
