Setup
1. Power up the sled and set LENS IN position
Slide the lens into the middle of the sled before powering up. Plug the power adaptor into an AC
outlet, then into the back of the unit as illustrated. Using the remote, press the “lens in” button. The
lens sled will slowly position itself into the factory default LENS IN position. The edge of the adaptor
plate will land about a half-inch from the motor housing side of the sled. If the bracket is in front of the
projector lens, proceed to the next step (Verify centering).
If the bracket is not in front of the projector lens, you will need to change the setting. Simply press
the LENS OUT button on the remote, and wait for the bracket to move in front of the projector lens.
Press and hold the LENS OUT button again for 5 seconds. The sled will confirm the new setting by
moving the bracket away from the projector lens to the new LENS OUT location. The edge of the
adaptor plate will land about a half-inch from the motor housing side of the sled. You have now re-
programmed the sled. This setting will be preserved in the unit even if it is unplugged or undergoes a
power failure. To change back, just repeat the above procedure.
2. Verify centering
Press LENS IN and see where the lens stops. If needed, make small adjustments (+ or – a quarter-
inch) to the lens bracket after disconnecting the power, by loosening the screws and sliding the
bracket to the left or right as
needed to achieve centering.
Reconnect the power and check
the centering. The optical sensors
will stop the edge of the lens
adaptor plate approximately a half-
inch from the housing on either side
of the sled. You can use this gap
on the motor or the pulley side for
fine-tuning adjustments.
