Reading the Indicators
The projector is provided with the following three indicators that indicate
the status of the projector.
A
Indicates the operating status. Standby condition
When the [t] button is
pressed in this status,
projection starts.
Preparing for network
monitoring or cool down in
progress
Buttons are disabled while
the indicator is flashing.
Warming up
Warm-up time is about 30
seconds. After warm-up is
complete, the indicator stops
flashing.
Projecting
B
Indicates the internal temperature status.
C
Indicates the lamp status.
See the following table for the status of indicators and how to resolve the
problems.
If all indicators are off, the power cable is not connected correctly or the
power is not being supplied normally.
Sometimes, when the power cable is unplugged, the [
t] indicator remains
lit for a short period, but this is not a fault.
