CALIBRATION PROCEDURES 2

DO NOT REMOVE OR INSERT MODULES OR SUB-ASSEMBLIES
WITH POWER APPLIED. DOING SO MAY RESULT IN EXTENSIVE
DAMAGE TO ELECTRICAL COMPONENTS.
NOTES:
MEMORY ERASE - Pressing and holding the DeGauss/Mode switch for 30
seconds or longer will completely erase the entire custom area of
memory.
MEMORY FULL - The monitor will indicate that the custom format storage area
in non-volatile memory cannot accept the new format by blanking the screen
twice when either the normal or extended calibrate mode is initiated.
EXTENDED CAL. MODE - When sw1-4 is in the on position the monitor is in
"extended cal mode", this provides access to pincushion and trapezoid
adjustments. When sw1-4 is in the off position normal cal mode denies access
to pin and trap.
Apply power and input signals and allow the monitor to warm up for five minutes.
NOTE: When the monitor is placed in the Calibrate Mode a definite programmed sequence
of calibration steps must be followed. Refer to Table 1 for the sequence.
To enter the calibration mode, press and hold the DeGauss button for five seconds.

CONTRAST ADJUSTMENT

The monitor will indicate that it is in the contrast adjustment by momentarily reducing the
image intensity and then returning it back to the original or stored value.
Adjust the contrast by rotating the contrast control slowly until the control "locks on" and
then set for the desired picture intensity. Normally this will be left at fully clockwise or
maximum gain.
To advance to the Vertical Position adjustment mode, press and release the
DeGauss/Mode switch.

VERTICAL POSITION ADJUSTMENT

The monitor will indicate that it is in the vertical position mode by momentarily shifting the
image down and then back to the original or stored position.
Adjust the vertical position by rotating the contrast control slowly until the control "locks
