POWER MANAGEMENT
The power saving mode complies with the VESA Display Power Management Signaling standard.  Each state of power management shall be activated 
by the host computer terminating the appropriate sync signals.  Blanking the video must precede termination of the sync signals.  The elapsed time 
counter shall also be controlled by the host computer.  Reactivation of the monitor shall be accomplished from the host computer by re-establishing the 
normal sync signal.
TIMING SPECIFICATION
SELF DIAGNOSIS FUNCTION
When a failure occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the problem.  If there is more than 
one error, the lamp will identify the first of the problem areas.
