Installing the Projector (Cont.) Effective Range and Distance of the Remote Control Unit The operable distance of the remote control unit (A) is approx. 32.81 ft (approx. 10 m) and the operable angles of the remote control unit is 50° right to left, and 15° up and down. The effective range and distance of the remote control unit A EMERGENCTYEMPLAMOPPERATE STAND BY 15˚ 15˚ Remote control unit 50˚ 50˚ Projector DLA-L20U Notes • Operate the remote control unit aiming signal transmitter of the remote control directly at the remote sensor on the projector. The remote control may not work correctly if there is a shielding object between the remote control and the remote sensor. • When the effective distance or operation of the remote control becomes unstable, replace the batteries with new ones. Setting the Position Selecting Screw for Ceiling Mounting When using the projector in an upside-down, ceiling-mounted position (inverted top-to-bottom and right-to-left), the "position selecting screw for ceiling mounting" must be turned to switch to ceiling mounting. This will correct variance in color images (shading), which otherwise would occur in ceiling mounting. To revert to normal desktop setting, turn the "position selecting screw for ceiling mounting" back to the initial position (factoryshipped). [When using the projector in an upside-down, ceiling mounting position (inverted top-to-bottom and right-to-left)] s Turn the "position selecting screw for ceiling mounting" counterclockwise fully (until it is turning idly).
