10、ASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER! Avoid prolonged, unprotected contact between solder 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,

11、wash your hands before handling food. 1. Critical Components Information Components having special characteristics are marked and must be replaced with parts having specifications equal to those originally installed. 2.

12、ed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits. Meter impedance should be equivalent to 1500 ohms shunted by 0.15 F. For U model “CAUTION” “F3701: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 6A, 125V FUSE

13、.” For C model CAUTION F3701: REPLACE WITH SAME TYPE 6A, 125V FUSE. ATTENTION F3701: UTILISER UN FUSIBLE DE RECHANGE DE MME TYPE DE 6A, 125V. 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,

14、 it is recommended to use one of the following 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 so
