Furthermore, special parts which have purposes of fire-retardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. are used. When replacing any of components, be sure to use only manufacturer's specified oarts shown in the oarts list. Caution ! lC, LSI and VLSI are sensitive to static electricity. Secondary trouble can be prevented by taking care during repair, .Cover the parts boxes made of olastics with aluminium foil. .Put a conductive mat on the work table. .Ground the soldering iron. .Do not touch the pins of lC, LSI or VLSI with fingers directly u DT IICT NG DtTtCTI]\G CAUTION : FOR CONTINUED PROTECTION AGAINST FIRE HAZARD, REPLACE ONLY STVTCF (l)aRC.i T SWITCH (2) CIRCUIT WITH SAME TYPE F1 1.6A 125V FUSE RISK OF FIRE-REPLACE FUSE AS MARKED FUSE CAUTION €EF These symbols located near the fuse indicates that the fuse used is a fast operating type.
