When the indicating lamp lights orange or the message “No Sync. Signal”, “Power Save” or “Invalid Scan Freq.” appears on the screen, there is something unusual about the status of reception.
See “Power Save Mode” or “Symptoms That Seemingly Appear to be Failures.” 
ATTENTION
•Avoid repeatedly turning the monitor on and off at short time intervals. Failures might result from such operation.
•Turn off the main power switch before leaving the monitor out of use for an extended period of time.
•If a power failure occurs while the main unit is running, it will
be powered on upon recovery from the failure. Turn off the unit's main power switch to avoid power surges upon recovery.
