TO SERVICE PERSONNEL1. Critical Components Information

Components having special characteristics are marked Zand must be replaced with parts having specifications equalto those originally installed.

2. Leakage Current Measurement (For 120V Models Only)When service has been completed, it is imperative to verifythat all exposed conductive surfaces are properly insulatedfrom supply circuits.

Meter impedance should be equivalent to 1500 ohm shuntedby 0.15F.

AC LEAKAGETESTER OREQUIVALENT

EQUIPMENTUNDER TEST

INSULATINGTABLE

WALLOUTLET

Leakage current must not exceed 0.5mA.

Be sure to test for leakage with the AC plug in bothpolarities.

WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/orplastic (where applicable) components may also contain traces of chemicals found by the California Health andWelfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FORANY REASON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumesor expose eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your handsbefore handling food.

About Lead Free Solder / The P.C.B.s installed in this unit are soldered using the fol-lowing solder.

Sn+Ag+Cu ++Sn+Cu +Sn+Zn+Bi ++

Among some types of lead free solder currently available, itis recommended to use one of the following types for therepair work.

Sn + Ag + Cu (tin + silver + copper) Sn + Cu (tin + copper) Sn + Zn + Bi (tin + zinc + bismuth)

CAUTIONF1, F2 : FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 10A, 125V FUSE.

CAUTIONF1, F2 : REPLACE WITH SAME TYPE 10A, 125V FUSE.

Caution:1. As the melting point temperature of the lead free solder is

about 30C to 40C (50F to 70F) higher than that of thelead solder, be sure to use a soldering iron suitable toeach solder.

2. If lead solder must be used, be sure to remove lead-freesolder from each terminal section of the parts to be re-placed and from the area around it completely before sol-dering, or make sure that the lead free solder and leadsolder melt together fully.

The protection function worked due to a DCvoltage appearing at the speaker terminal.A cause could be a defect in the amplifier. Ifthe power is turned on with the abnormalityunsolved, the protection function works inabout 3 seconds to turn off the power.

The protection function worked due to a de-fect or overload in the power supply. If thepower is turned on with the abnormality un-solved, the protection function works in about1 second to turn off the power.

The protection function worked due to thetemperature limit being exceeded. Causescould be poor ventillation or a defect relatedto the thermal sensor. If the power is turnedon with the abnormality unsolved, the pro-tection function works in about 1 second toturn off the power.

History of protection functionWhen the protection function has worked, its history is storedin memory with a backup. Even if no abnormality is noted whileservicing the unit, an abnormality which has occurred previ-ously can be defined as long as the backup data has beenstored.The history of the protection function is cleared when DIAG iscancelled by selecting PRESET RESERVED (Memory initial-ized) of DIAG menu No.10 or when the backup data is erased.

Cut off

1. Immediately after the power is turned on, measure thevoltage across resistor terminals in the column A inthe table below and confirm that the measured value isbetween 0.1mV and 10.0mV.

2. If the measured voltage exceeds 10.0mV, open (cutoff)the resistor in the column B in the table below and re-confirm the voltage.Attention:If the idling current exceeds 10.0mV after a power ampli-fier repair, check for a defective component before cut-ting the resistor.

3. Confirm that the voltage is between 0.2mV and 15.0mVafter 60 minutes.
