• When the input signal cannot be detected, the message
"NO SYNC" is displayed.
• The present frequency (or color system or DTV format) is
detected and displayed. The horizontal (kHz) and vertical
(Hz) frequencies are displayed with decimal fractions omitted.
• The frequency displayed may differ from the actual frequency
due to processing dispersion.
• [OOkHz OOHz] shown in the table displays the present frequency
detected.
• The horizont~I (kHz) and vertical (Hz) frequencies are displayed with
decimal fractions omitted.
• The frequency displayed may differ from the actual frequency due to
processing dispersion.
■
User Memory for RGB Input
• The RGB signals input to INPUT A or INPUT C may require
some adjustments, depending on the signal's characteristics.
If necessary, perform the required adjustments referring to
"How
to Perform Main Menu Adjustments" on pages 10-11.
The adjusted contents are automatically stored in memory
(User Memory).
When a signal corresponding to one stored in the User
Memory is input, the stored adjustment contents are recalled.
This unit stores the adjusted contents of up to 12 different
signals in memory.
When the 13th signal is input, the signal first stored in
memory is replaced (overwritten) by the new one. (The
contents stored first are replaced first.)

disappears after about three seconds, and degaussing
is complete after about 1 0 seconds.
( Notes: )
• When the power of the monitor is turned on, the degaussing
circuit is automatically activated.
• Do not place a floppy disk or credtt card close to the
monitor. The magnetic field generated by the monitor may
erase its contents.
• When degaussing the screen by manually activating the
degaussing circuit, wait more than 30 minutes to gain the
best effect. (The shorter the interval is, the less effective
degaussing is.)
