                                                 ANODE CAP REMOVAL PROCEDURE
WARNING: High voltage remains in the CRT even after the power is disconnected. To avoid electric shock, discharge CRT before attempting to  
remove the anode cap.  Short between anode and coated earth ground strap of CRT. 
NOTE:  After removing the anode cap, short circuit the anode of the picture tube and the anode cap to either the metal chassis, CRT shield, or carbon 
painted on the CRT. 
REMOVAL PROCEDURES
HOW TO HANDLE AN ANODE CAP
1.  Do not use sharp objects which may cause damage to the surface of the anode 
cap. 
2.  To avoid damaging the anode cap, do not squeeze the rubber covering too 
hard. A material fi tting called a shatter-hook terminal is built into the rubber. 
3.  Do not force turn the foot of the rubber cover. This may cause the shatter-hook 
terminal to protrude and damage the rubber.
Turn up one side of the rubber cap in 
the direction indicated by arrow  a  .
Use your thumb to pull the rubber
cap fi rmly in the direction indicated
by arrow  b  .
When one side of the rubber cap separates from 
the anode button, the anode cap can be removed 
by turning the rubber cap and pulling it in the 
direction of arrow  c  .
