About Error Codes

List of the Projection Distance by Angle of Optical Axis
When a critical operational error
occurs, the power will be
automatically turned off and the error
code will light up on the error code
window inside the projector. You can
check the code without removing the
cover. Refer to the chart below for the
meanings.

Notes
• When the error code lights up, the previous adjustment data may be cleared.
• The error code disappears when the MAIN POWER switch is turned off and the power cord is disconnected.
• The error code lights up every time the power is turned on until the critical operational error is returned to normal.
• Immediately after the MAIN POWER switch is turned on, "88" is displayed for about one second. This is not a problem.
The unit resets the CPUs to the initial status during this period.
