The CP4220 lens should be centered and parallel with the screen. This orientation ensures optimum lens
performance with minimal offset. If this position is not possible (such as when the projector is significantly
higher than the center of the screen), it is better to rely on offset rather than extra tilt.
Use a protractor to measure the degree of screen tilt and then extend or retract the projector feet to match this
angle.
NOTE: The front-to-back tilt of the projector must not exceed 15°. This limit ensures safe lamp operation and
the proper positioning of the liquid cooling reservoir
To adjust the vertical or horizontal position of the projector, extend or
retract the adjustable feet on the bottom of the projector by rotating them.
Once the required adjustment is made, tighten the lock nut.
If you need to adjust the vertical or horizontal position of the projector
beyond what the standard feet allow, you can install two 6 inch extension
rods to increase the amount of adjustment. To install the extension rods
safely:
1. Prop the rear of the projector up to access and remove the two rear
feet. This can be done by one person holding the back end of the
projector up slightly so another person can unthread the feet OR by
propping up the back of the projector with a sturdy object.
2. Add the extension rods to the standard feet.
3. Thread the newly extended feet back into the projector's baseplate.
Adjust the feet until the desired tilt is achieved.
4. Lock the feet in place by turning each lock nut until it fits tight against the projector.
