Introduction
This manual provides the technical information necessary for servicing the VX-8GR 144/430 MHz Dual-Band FM Transceiver.
Servicing this equipment requires expertise in handing surface-mount chip components. Attempts by non-qualified persons to service this equipment may result in permanent damage not covered by the warranty, and may be illegal in some countries.
Two PCB layout diagrams provided for each double-sided board in this transceiver. Each side of the board is referred to by the type of the majority of components installed on that side ("Side A" or "Side B"). In most cases one side has only chip components, and the other has either a mixture of both chip and leaded components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.
While we believe the information in this manual to be correct, VERTEX STANDARD assumes no liability for damage that may occur as a result of typographical or other errors that may be present. Your cooperation in pointing out any inconsistencies in the technical information would be appreciated.
Important Note
1)This transceiver was assembled using Pb (lead) free solder, based on the RoHS specification.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this apparatus. The solder stated above utilizes the alloy composition required for compliance with the lead-free specification, and any solder with the above alloy composition may be used.
2)Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.

Introduction and Precautions
The 
has been carefully aligned at the factory for the specified performance across the specified amateur bands. Realignment should therefore not be necessary except in the event of a component failure. All component replacement and service should be performed only by an authorized VERTEX STANDARD representative, or the warranty policy may be voided.
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 are replaced, 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 must reserve 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 the need for realignment determined to be absolutely necessary.

Alignment Preparation & Precautions
A 10-W RF dummy load and in-line wattmeter must be connected to the main antenna jack in all procedures that call for transmission, alignment is not possible with an antenna. After completing one step, read the next step to see if the same test equipment is required. If not, remove the test equipment (except dummy load and wattmeter, if 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 68~86°F (20~30°C). When the transceiver is brought into the shop from hot or cold air, it should be allowed some 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 0 dBµ=0.5 µV (closed circuit).

Alignment
Internal System Alignment Routine
This uses a programmed routine in the transceiver which simplifies many previously complex discrete component settings and adjustments with digitally-con- trolled settings via front panel buttons and LCD indications.
1.To begin, set the transceiver to the VFO mode on the "A-Band" in the "Mono" band mode.
2.Program a password for the Alignment (AH041M) according to the following procedure:
1)Press and hold the [MENU] key for one second to enter the Set mode.
2)Rotate the DIAL knob to select Set Mode Item 16: CW ID.
3)Press the [MENU] key briefly to enable adjustment of this Set Mode Item.
4)Rotate the DIAL knob to select "ON".
5)Press the [MODE] key, then press and hold in the [HM/RV] key for two seconds to clear any previous entry.
6)Program the password "AH041M" using the DIAL knob (select the character), and [BAND]/[MODE] key (move the cursor).
7)When you have completed the password, press the
[MENU] key briefly, then press the PTT switch to exit to normal operation.
Remember to delete the password "AH041M"from the Set Mode Item 16: CW ID when the alignment adjustments are finished by pressing and holding in the [HM/ RV] key for two seconds (as in step 5 above).
3.Press the [PWR] switch for two seconds to turn the transceiver "off".
4.Press and hold in the [HM/RV] key while powering the transceiver "on" again. The transceiver will enter the adjustment mode, and the display will show the first alignment setting. Thereafter, the frequencies used during alignment will automatically be set without action by the technician.
