*   In this mode, the signal appears in one of three ways:  The Horizontal Sync Signal alone off, the Vertical Sync Signal 
    alone off, or both signals off.     

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.

When a failure occurs, the STANDBY/TIMER lamp will fl ash 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 fi rst of the problem areas.
