Power and Start-Up Problems

When AC power is applied to the unit by turning on the main AC power
switch, the unit enters a 3-minute standby-delay sequence. During this time,
the STBY lamp on the rear panel flashes and the Lamp and Fan lamps are
off. Also during this time, the unit does not respond to remote or manual
controls and alerts you that it is locked by giving 3 short beeps when you
press a button on the remote control.
The unit enters the standby mode when the 3-minute standby delay is
complete. This is shown when the STBY lamp comes steadily on. At this
time the unit is ready to accept an "ON" command.
This is the sequence of events that must occur for a WN-5220-V to light the
lamp and display an image.
