CAUTIONS FOR ADJUSTMENT AND REPAIR
• Degaussing is always required when adjusting purity or convergence.
I
• Adjustment procedures at the factory use a white balance meter; procedures given in this manual rely on a
visual check of white balance.
• Allow 20 minutes warm-up time for the display before checking or adjusting only electrical specification or
function.
• Reform the leadwire after any repair work.
CAUTION FOR SERVICING
• In case of servicing or replacing CRT, high voltage sometimes remains in the anode of the CRT.
Completely discharge high voltage before servicing or replacing CRT to prevent a shock to the serviceman.
