the industry with a vertical frequency from 56 Hz to 76 Hz and with a
horizontal frequency from 30 kHz to 61 kHz. If the input frequency
is out of this specified range, the monitor shall display a warning
screen indicating that the input frequency is out of range. Under no
circumstances shall any combination of input signals cause any
damage to the monitor.

the operating mode is not one of those stored in memory, the monitor
CPU will automatically start the Auto-Adjustment process.
screen parameters may be adjusted by the use of the front bezel
controls and then may be saved as a user defined mode. The monitor
shall include the following preset video timings
