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 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 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 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). 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. VX530 Series Operating Manual 3/6 Vertex Standard Co., Ltd.

FCC ID: K6610524420 IC ID: 511B-10524420 Circuit Description 1/3 Vertex Standard Co., Ltd. VX-537 Circuit Description 1 Overview The VX-537 is a UHF/FM hand-held transceiver designed to operate in the frequency range of 450 to 490 MHz. 2 Circuit Configuration by Frequency The receiver is a double-conversion superheterodyne with a first intermediate frequency (IF) of 44.25 MHz and a second IF of 450 kHz. Incoming signals from the antenna are mixed with the local signal from PLL to produce the first IF of 44.25 MHz. This is then mixed with the 43.8 MHz second local oscillator (using the 14.6 MHz 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 L1003, L1004, L1006, L1008, L1001, L1002, L1005, L1007, L1009 & L1010, capacitors C1003, C1004, C1006, C1008, C1011, C1014, C1022, C1025, C1002, C1005, C1007, C1009, C1013,C1017,C1018, C1020, C1021, C1204, C1028 & C1031 and antenna switching diode D1004. Signals within the frequency range of the transceiver are then amplified by Q1005 and enter a varactor-tuned band-pass filter consisting of coils L1016, L1017 & L1019, capacitors C1052, C1053, C1060, C1063, C1067, C1068, C1070, C1072, C1073, C1074, C1082, C1084 & C1092 resisters R1024, R1033 and R1048, and diodes D1008, D1009, D1010, D1011, D1012 & D1013 before first mixer. 3-2 First Mixer Buffered output from the VCO is amplified by Q1012 to provide a pure first local signal between 405.75 and 445.75 MHz for injection to the first mixer Q1032. The 44.25 MHz first mixer product then passes through monolithic crystal filters XF1001 to strip away all but the desired signal. 3-3 IF Amplifier The first IF signal is amplified by Q1027. The amplified first IF signal is applied to FM IF subsystem IC Q1023 which contains the second mixer, second local oscillator, limiter amplifier, noise amplifier, and S-meter amplifier. A second local signal is generated by Q1024 using the 14.6 MHz crystal X1001 as a reference, producing a 43.8 MHz signal which yields a 450 kHz second IF when mixed with the first IF signal within Q1023. The second IF then passes through the ceramic filter CF1001 (wide channels), CF1002 (narrow channels) to strip away unwanted mixer products, and is applied to the limiter amplifier in Q1023, which removes amplitude variations in the 450 kHz IF, before detection of the speech by the ceramic discriminator CD1001. 3-4 Audio Amplifier Detected audio from Q1023 is applied to Q2023 and audio low-pass filter, and then past the volume control (Q2017) to the audio amplifier Q2004 (external speaker) or Q2009 (internal speaker), providing up to 0.5 Watts to the optional headphone jack or 16-Ω loudspeaker. Attention: Audio output is BTL output. FCC ID: K6610524420 IC ID: 511B-10524420 Circuit Description 2/3 Vertex Standard Co., Ltd. 3-5 Squelch Control The squelch circuitry consists of a noise amplifier & band-pass filter within Q1023, and noise detector D1025, D1027. When no carrier received, noise at the output of the detector stage in Q1023 is amplified and band-pass filtered by the noise amplifier section of Q1023 and the network between pins 7 and 8, and then rectified by D1025 The resulting DC squelch control voltage is passed to pin 19 of the microprocessor Q2025. If carrier is received, this signal causes pin 6 of Q2026 to go low and pin 89 of Q2025 to go high. Pin 6 of Q2026 signals Q2005, Q2013 and Q2016 to disable the supply voltage to the audio amplifier Q2004 and Q2009, while pin 89 makes Q2006 hold the green (Busy) half of the LED off, when pin 6 of Q2026 is low and pin 89 of Q2025 is high. 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 Q2004, Q2009 to the loudspeaker by enabling the supply voltage to it via Q2005 and Q2011 . 4 Transmit Signal Path 4-1 Microphone Amplifier Speech input from the microphone is amplified in Q2030 after there is a filter and is sent to Q2017 and sent to Dummy Unit (or Optional Unit). The audio, which returned from Dummy Unit, passes Q2023 to be pre-emphasized. The processed audio is then mixed with a CTCSS tone generated by Q2023 and delivered to D1015 for frequency modulating the PLL carrier up to ±5 kHz from the unmodulated carrier at the transmitting frequency. If a CDCSS code is enabled for transmission, the code is generated by the microprocessor Q2025 and delivered to X1001 (TCXO 14.6 MHz) for CDCSS modulating. If DTMF is enabled for transmission, the tone is generated by the microprocessor Q2025 and applied to the splutter filter (Q2023) 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 microphone (main and sub) are input to the positive input (sub) and to the negative input (main) and of the Q2030. If the same signal is input to both main and sub, the main signal is canceled at the output of Pin1 of the Q2030. In other words, noise from nearby sources not directly connected to the transceiver enters the main and sub input at the same signal and is therefore canceled out. When a signal is only input to main and there is no signal at sub, the main signal is output as is from Q2030. 4-3 Drive and Final Amplifier The modulated signal from the VCO Q1022 is buffered by Q1032 and amplified by Q1017 and Q1013. The low-l…

FCC ID: K6610524420 IC ID: 511B-10524420 Alignment 1/6 Vertex Standard Co., Ltd. VX-537 Alignment Introduction The VX-530 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 Vertex Standard 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 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: K6610524420 IC ID: 511B-10524420 Alignment 2/6 Vertex Standard Co., Ltd. Required Test Equipment ・ RF Signal Generator with calibrated output level at 600 MHz ・ Deviation Meter (linear detector) ・ In-line Wattmeter with 5 % accuracy at 600 MHz ・ 50 Ω RF Dummy Load with power rating 10 W at 600 MHz ・ 16 Ω AF Dummy Load (Attention: Audio output is BTL output) ・ Regulated DC Power Supply (standard 7.5 V DC, 3 A) ・ Frequency Counter with 0.2 ppm accuracy at 600 MHz ・ AC Voltmeter ・ DC Voltmeter ・ UHF Sampling Coupler ・ IBM PC / compatible Computer with Microsoft DOS v3.0 or later operating system ・ Vertex Standard 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 to 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 0dBμ EMF = 1μV. Setup the test equipment as shown for transceiver alignment, apply 7.5V DC power to the transceiver.
