Front & Rear IR Sensors
The two IR sensors located on the projector receive transmissions from the IR remote from up to 100 feet
away. It is important to keep the transmission path to these sensors unobstructed for uninterrupted
communications with the projector. The rear IR sensor is located at the back of the projector between the status
LEDs and the front IR sensor is located next to the projector’s front nameplate.
Projection Lenses, Lens Mount and Other Features
The projector includes a motorized lens mount that allows automated lens control and adjustment: vertical and
horizontal offsets, zoom and focus. The lens mount can be fitted with any one of the available optional lenses –

Zoom and Focus

and focus. Adjust zoom to fit the displayed image on the screen and adjust focus to improve the clarity of the
image.
NOTES: 1)

2)
Use the lens cap when
transporting the lens to avoid scratching and damaging the lens, which could affect your displayed image.
3)
Motorized lenses should not be adjusted by hand without first setting them for manual operation,
otherwise the zoom and focus motors may be damaged. (Set in
