1. Function
Service mode permits the calibration of variable EAROM values.
2. Entering Service Mode
The Adjustment sequence for the service mode is indicated in the pictures:
“Arrangement of the service mode commands on the remote control” (p. 11).
The set is now in the service mode basic routine and documents this with the
following on-screen display.
3. Instructions on Geometry Alignment
Vertical amplitude, Vertical position, Vertical linearity, Vertical symmetrie, Hor.
amplitude, Hor. phase, E-W corr., Trapezium comp., etc will be adjustet
separately for 50/60Hz vertical frequencies. Therefore they have to be regulated
separately.
