H.V. remains in the CRT even after the power is
disconnected.

To avoid electrical shock, discharge CRT before
attempting to remove the anode cap :  Short between
anode and CRT coating earth ground strap.

 Do not use sharp objects which may cause damage to the sur-

face of the anode-cap.

 Do not squeeze the rubber covering too hard to avoid damag-

ing the anode-cap. A material fitting called a shatter-hook ter-
minal is built into the rubber.

 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

 When one side of the rubber cap sepa-

rates from the anode button, the anode-
cap can be removed by turning the rub-
ber cap and pulling it in the direction of

 Use your thumb to pull the rubber cap

firmly in the direction indicated by
arrow

NOTE:   Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or carbon painted on the CRT, after
removing the anode.
