    [Important Check Points for Good Servicing]In this manual, procedures that must be performed during repairs are marked with the below symbol.Please be sure to confirm and follow these procedures.

    1. Product safety

    Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by following the safety instructions described in this manual.

    1 Use specified parts for repair.

    Use genuine parts. Be sure to use important parts for safety.

    2 Do not perform modifications without proper instructions.

    Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as radio/TV interference and foreign noise.

    3 Make sure the soldering of repaired locations is properly performed.

    When you solder while repairing, please be sure that there are no cold solder and other debris.Soldering should be finished with the proper quantity. (Refer to the example)

    4 Make sure the screws are tightly fastened.

    Please be sure that all screws are fastened, and that there are no loose screws.

    5 Make sure each connectors are correctly inserted.

    Please be sure that all connectors are inserted, and that there are no imperfect insertion.

    6 Make sure the wiring cables are set to their original state.

    Please replace the wiring and cables to the original state after repairs.In addition, be sure that there are no pinched wires, etc.

    7 Make sure screws and soldering scraps do not remain inside the product.

    Please check that neither solder debris nor screws remain inside the product.

    8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.

    Damaged power cords may lead to fire accidents, so please be sure that there are no damages.If you find a damaged power cord, please exchange it with a suitable one.

    9 There should be no spark traces or similar marks on the power plug.

    When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary.

    a Safe environment should be secured during servicing.

    When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely.

    2. Adjustments

    To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.Adjustments should be performed in accordance with the procedures/instructions described in this manual.

    4. Cleaning

    For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances.

    3. Lubricants, Glues, and Replacement parts

    Use grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied.

    5. Shipping mode and Shipping screws

    To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment. Please be sure to follow this method especially if it is specified in this manual.

    1. SERVICE PRECAUTIONS1.1 SERVICE PRECAUTIONS

    1.2 NOTES ON SOLDERING

    1. You should conform to the regulations governing the product (safety, radio and noise, and other

    regulations), and should keep the safety during servicing by following the safety instructions described in this manual.

    2. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic induction.

    3. There is a danger for electrical shock in the periphery of an area where “!” is indicated on the printed circuit board due to a high voltage being generated daring operation. Therefore, be careful when working around such areas.

    For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering.

    Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron.

    Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden).

    The following lead-free solders are available as service parts: Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.
