10、RX-V373/HTR-3065 This product contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive harm. DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid prolonged, unprotected contact between solde

11、r and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor! If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food. 1. Critical Components Information Components having special character

12、istics are marked and must be replaced with parts having specifications equal to those originally installed. 2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circu

13、its. Meter impedance should be equivalent to 1500 ohms shunted by 0.15 F. TO SERVICE PERSONNEL Leakage current must not exceed 0.5mA. Be sure to test for leakage with the AC plug in both polarities. WARNING: CHEMICAL CONTENT NOTICE! For U model “CAUTION” “F1501: FOR CONTINUED PROTECTION AGAINST RISK

14、 OF FIRE, REPLACE ONLY WITH SAME TYPE 6A, 125V FUSE.” For C model CAUTION F1501: REPLACE WITH SAME TYPE 6A, 125V FUSE. ATTENTION F1501: UTILISER UN FUSIBLE DE RECHANGE DE MME TYPE DE 6A, 125V.

15、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 30 40程度高、 合 使用。 All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder. Among some types of lead free solder currently available, it is recommended to use one of the following

16、types for the repair 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 is about 30C to 40C (50F to 70F) higher than that of the lead solder, be sure to use a soldering iron suitable
