Removing the Existing Lens
1.
Push the LENS RELEASE button all the way in and rotate the lens counterclockwise. The existing lens will be
disengaged
2.
Pull out the existing lens slowly.
Important:
 When installing the lens into the projector, be sure to remove the lens cap from the back of the
optional lens before installing the optional lens into the projector. Failure to do so will cause damage
to the projector and lens.
 There is one safety switch inside the projector's lens slot to prevent unexpected injury by laser
beam. The projector cannot be turned on if the projection lens has not been installed or is not
installed correctly. Please make sure the lens is installed properly before tuning on the projector.
