If you want to change formats we suggest you contact your Da-Lite Dealer to make the adjustments for you. The mask surface and the projection screen must be adjusted separately. The following instructions walk you through this process. 2 SCREEN ADJUSTMENT SCREEN ADJUSTMENT (MOTOR 1) 1. Remove the cover plate from the wall switch, and then remove the switch from the box. If you go past the desired position, press the stop button to stop the screen and then press the up arrow to return the screen to a position above the new stop point and try again until the screen stops at the new position. The new stop point can now be assigned to whichever format location you want, button 2, 3 or 4. Repeat this process for any other changes to the remaining 2 locations. Make sure the power is disconnected to the screen, then insert the T4 cable marked motor 2 in the jack it was disconnected from on the bus interface control and reconnect the T6 cable to the T6 adapter. If you go past the desired position, press the stop button to stop the mask and then press the up arrow to return the mask to a position above the new stop point and try again until the mask stops at the new position. The new stop point can now be assigned to whichever format location you want, button 2, 3 or 4. Repeat this process for any other changes to the remaining 2 locations. Make sure the power is disconnected to the screen, then insert the T4 cable marked motor 1 in the jack it was disconnected from on the bus interface control, shut the cover and fasten the screw. LIMIT CONTROL ADJUSTMENT This procedure will reset the stop positions for the "up" button and button 1. If you have a wall switch with just two T6 connectors on the bottom you will need to use a separate 3-button switch for this operation. Otherwise you will use the wall switch that controls the bus interface unit. Remove cover screw from bus interface unit located on the motor end of screen case. Locate the T4 wires coming from the motors to the bus interface (see wiring diagram). Unplug the T4 wire of the motor to be adjusted from the bus interface unit and plug it into the top left RJ22 4-pin connector of wall switch. Press and hold the 1 button on the switch to run the screen down to the desired position. [. . . ] CONTACT CLOSURE MUST BE MAINTAINED FOR AT LEAST 1 SECOND AND NOT MORE THAN 3 SECONDS.
