In addition, other electrical/electronic and/or plastic (whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (andpossibly 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 FOR ANY REA-SON WHATSOEVER!Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or exposeeyes to solder/flux vapor!If you come in contact with solder or components located inside the enclosure of this product, wash your hands beforehandling food.1. Critical Components InformationComponents having special characteristics are marked sand 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.GMeter impedance should be equivalent to 1500 ohms shuntedby 0.15F.GLeakage current must not exceed 0.5mA.GBe sure to test for leakage with the AC plug in both polarities.本機搭載基板付接合部無鉛付。無鉛種類、修理時下記無鉛使用推奨。Sn+Ag+Cu （錫+銀+銅）Sn+Cu （錫+銅）Sn+Zn+Bi （錫+亜鉛+）注意：無鉛融点温度通常鉛入比3040程度高、合使用。All of the P.C.B.s installed in this unit and solder joints aresoldered using the lead free solder.Among some types of lead free solder currently available,it is 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)Caution:As the melting point temperature of the lead free solder isabout 30C to 40C (50F to 70F) higher than that of the leadsolder, be sure to use a soldering iron suitable to each solder.About lead free solder / 無鉛I TO SERVICE PERSONNELFor U model“CAUTION”“F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 1.6A,125V FUSE.”For C modelCAUTIONF1:REPLACE WITH SAME TYPE 1.6A, 125V FUSE.ATTENTIONF1:UTILISER UN FUSIBLE DE RECHANGE DE MME TYPE DE 1.6A, 125V.RadioFans.CN 收音机爱 好者资料库YST-FSW150/YST-FSW0503435 (17-1/8)151 (5-15/16)130 (5-1/8)21(13/16)350 (13-3/4)7(1/4)3(1/8)360 (14-3/16) (5-15/16)151437 (17-3/16)(14-11/16)373Stand縦置用When installing the unit vertically（本機縦置場合）163 (6-7/16)142 (5-9/16)21(13/16)(13-3/4)350350 (13-3/4)7(1/4)3(1/8)360 (14-3/16) (6-7/16)163352 (13-7/8)When installing the unit vertically（本機縦置場合）(14-3/16) 360Type / 型式 .
