4-1-1 Before Making Adjustments
4-1-1 (a) ORIENTATION
When servicing, always face the monitor to the
east.
4-1-1 (b) MAGNETIC FIELDS
Whenever possible, use magnetic field isolation
equipment such as a Helmholtz field to surround
the monitor. If a Helmholtz field is not available,
frequently degauss the unit under test.
Caution:
Other electrical equipment may cause
external magnetic fields which may
interfere with monitor performance.
Use an external degaussing coil to limit magnetic
build up on the monitor. If an external degaussing
coil is not available, use the internal degaussing
circuit. However, do not use the internal
degaussing circuit more than once per 30 minutes.
4-1-1 (c) WARM-UP TIME
The monitor must be on for 30 minutes before
starting alignment. Warm-up time is especially
critical in color temperature and white balance
adjustments.
4-1-1 (d) SIGNAL
Analog, 0.7 Vp-p positive at 75 ohm, internal
termination
Sync: TTL level, negative/positive
4-1-1 (e) SCANNING FREQUENCY
Horizontal: 30 kHz ~ 68 kHz (Automatic)
Vertical:
50 Hz ~ 160 Hz (Automatic)
Unless otherwise specified, adjust at the
1024 x 768 mode (68 kHz/85 Hz) signal.
