DISASSEMBLY INSTRUCTIONS 3. After one side is removed, pull in the opposite direction to remove the other. 1. REMOVAL OF ANODE CAP Read the following NOTED items before starting work. * * NOTE After turning the power off there might still be a potential voltage that is very dangerous. When removing the Anode Cap, make sure to discharge the Anode Cap's potential voltage. Do not use pliers to loosen or tighten the Anode Cap terminal, this may cause the spring to be damaged.

DISASSEMBLY INSTRUCTIONS 3. When IC starts moving back and forth easily after desoldering completely, pickup the corner of the IC using a tweezers and remove the IC by moving with the IC desoldering machine. (Refer to Fig. 2-3.) 2. REMOVAL AND INSTALLATION OF FLAT PACKAGE IC REMOVAL NOTE 1. Put the Masking Tape (cotton tape) around the Flat Package IC to protect other parts from any damage. (Refer to Fig. 2-1.
