* HOW TO HANDLE AN ANODE-CAP
@ Don't hurt the surface of anode-caps with
sharp shaped material!
@ Don't press the rubber hardly not to hurt
inside of anode-caps!
A material fitting called as shatter-hook
terminal is built in the rubber.
@ Don’t turn the foot of rubber over hardly!
The shatter-hook terminal will stick out or
hurt the rubber.

SET-UP ADJUSTMENTS
@ The following adjustments should be made when Perform the adjustments in order as follows:
a complete realignment is required or a new 1. Beam Landing
picture tube is installed. 2. Convergence
@ These adjustments should be performed with 3. Focus
rated power supply voltage unless otherwise noted. 4. Screen (G 2) and White Balance
The controls and switch below should be set as follows Note: Test Equipment Required.

5. Oscilloscope
Preparation:
@ Set the side of the unit with the PICTUE TUBE so
that it faces east or west in order to reduce the
influence of external magnetic force.
@ Turn the power switch for the unit ON and erase
the magnetic force using a degausser..
