1 Safety Precautions
1.1.GENERAL GUIDELINES
1.When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.
2.After servicing, ensure that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
3.After servicing, check for leakage current checks to prevent from being exposed to shock hazards.
1.1.1.LEAKAGE CURRENT COLD CHECK
1.Unplug the AC cord and connect a jumper between the two prongs on the plug.
2.Using an ohmmeter measure the resistance value, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis, the reading should be between 1MΩ and 5.2Ω.
When the exposed metal does not have a return path to the chassis, the reading must be 
.
Fig. 1
1.1.2.LEAKAGE CURRENT HOT CHECK (See Figure 1.)
1.Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.
2.Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15µF capacitors, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1.
3.Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor.
4.Check each exposed metallic part, and measure the voltage at each point.
5.Reverse the AC plug in the AC outlet and repeat each of the above measurements.
6.The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent) may be used to make the hot checks, leakage current must not exceed 1/2 milliamp. Should the measurement is outside of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and re-checked before it is returned to the customer.

2 Caution for AC Mains Lead
4
RX-ES29GC / RX-ES29GS / RX-ES29GT
3 Before Use
Be sure to disconnect the mains cord before adjusting the voltage selector. Use a minus (-) screwdriver to set the voltage selector (on the rear panel) to the voltage setting for the area in which the unit will be used.
(If the power supply in your area is 117V or 120V, set to the “127V” position.)
Note that this unit will be seriously damaged if this setting is not made correctly. (There is no voltage selector for some countries; the correct voltage is already set.)
4 Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C131, C231, C301, C307, C309, C310 and C331 through a 10 Ω, 1 W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screw driver blade, for instance), as this may destroy solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
( For GC/GS) Current consumption at AC 220-240 V / 117 V, 50/60 Hz in NO SIGNAL mode should be ~180 mA, ~200mA respectively.
(For GT) Current consumption at AC 110 V, 60 Hz in NO SIGNAL mode should be ~150 mA respectively.
5 Protection Circuitry
The protection circuitry may have operated if either of the following conditions are noticed:
·No sound is heard when the power is turned on.
·Stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.
If this occurs, follow the procedure outlines below:
1.Turn off the power.
2.Determine the cause of the problem and correct it.
3.Turn on the power once again after one minute.
Note:
When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.
6 Handling the Lead Solder
6.1.About lead free solder (PbF)
Distinction of PbF P.C.B. :
P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.
Caution:
·Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C).
·Pb free solder will tend to splash when heated too high (about 1100°F/600°C).
·When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the soldering points with the Pb free solder until it melts enough.

7 Precaution of Laser Diode
CAUTION:
This unit utilizes a class 1 laser.
Invisible laser radiation is emitted from the optical pickup lens.
When the unit is turned on:
1.Do not look directly into the pick up lens.
2.Do not use optical instruments to look at the pick up lens.
3.Do not adjust the preset variable resistor on the pickup lens.
4.Do not disassemble the optical pick up unit.
5.If the optical pick up is replaced, use the manufacturer’s specified replacement pick up only.
6.Use of control or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
CAUTION!
THIS PRODUCT UTILIZES A LASER.
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

8 Handling Precautions For Traverse Deck
The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body.
So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
l Handling of CD traverse deck (optical pickup)
1.Do not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive to electrical shock.
2.The short land between the No.4 (LD) and No.5 (GND) pins on the flexible board (FFC) is shorted with a solder build-up to prevent damage to the laser diode.
3.Take care not to apply excessive stress to the flexible board (FPC board) (Fig 8.1).
4.Do not turn the variable resistor (laser power adjustment). It has already been adjusted.
Fig 8.2
Caution when Replacing the Optical Pickup :
The traverse has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sure to remove the solder from the short point before making connections.
Fig 8.1
l Grounding for electrostatic breakdown prevention
1.Human body grounding (Fig 8.2)
Use the anti-static wrist strap to discharge the static electricity from your body.
2.Work table grounding (Fig 8.2)
Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is placed, and ground the sheet.
Caution :
The static electricity of your clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch the traverse deck (optical pickup).
