To center the projected
image

mounting base.
• Rotate the adjustment screw clockwise to move the entire image to the left.

Resetting the lamp timer
After you replace the lamp, access the projector service menu to reset the lamp hour
counter. To prevent accidental errors, only a system administrator should perform this
procedure.
CAUTION
• Always reset the lamp hours after you replace the lamp, because lamp
service reminders are based on the current hours of use.
• Do not adjust any settings in the service menu other than those listed in this
guide. Changing other settings can affect the operation of your projector and
invalidates your warranty.
To reset the lamp timer 1. Press the remote control buttons quickly in the following sequence to access the
service menu: Down-Up-Up-Left-Up.
2. Scroll to Lamp Hour Reset, and then press OK.
Both Lamp Hour values (Standard and Economy) are reset to zero.
CAUTION
Do not use the Lamp Hour Reset feature unless you have just replaced the
lamp. Resetting the lamp hour counter on an old lamp can result in lamp
failure and damage to the product which may not be covered by your
warranty.
NOTE
You’re unable to reset the Display Hours value because it’s the running total
of hours the projector has been in use.
