Read and understand all instructions before using. 2. Position the cord so that it will not be tripped over, pulled, or contact hot surfaces. 3. If an extension cord is necessary, a cord with a current rating at least equal to that of the appliance should be used. Cords rated for less amperage than the appliance may overheat. 4. To reduce the risk of electric shock, do not disassemble this appliance. Contact an authorized service dealer when repair work is required. Incorrect reassembly can cause electric shock when the appliance is used subsequently. 5. The use of an accessory attachment not recommended by the manufacturer may cause a risk of fire, electric shock, or injury to persons. SAVE THESE INSTRUCTIONS

corresponding button on the six-button switch. Below is a list of each button function. IMPORTANT. When operating the switch, press and release the buttons. DO NOT hold the button for more than three (3) seconds or the button will be reprogrammed to the current screen position. ^ Returns the screen and mask to the up position. STOP Stops the screen and mask at any position when pressed. 1 Lowers screen to NTSC (1.33:1) format. Mask will travel down and reverse wrap on the roller. The mask is not used for this format. 2 Sets format to HDTV (1.78:1) 3 Sets format to Letterbox (1.85:1) 4 Sets format to Anamorphic (2.35:1) 2 INSTALLATION 1. Install screen by raising unit into position between joists at one end only. Install one lag screw in each mounting bracket. 2. Level unit lengthwise with a carpenter’s level and plumb level. Secure opposite end. CAUTION! Do not seal in until screen has been secured in position and properly tested for satisfactory operation. 3. Detach access panel by removing screws (Fig. 1). 4. Unwrap the two T6 cables that are attached to the bus interface control. Route them through the hole in the end of the screen case. 5. Run both T6 cables to the wall switch box and connect them to the double end of the 2 to 1, T6 phone jack adapter. 6. Plug one end of the remaining short T6 cable into the single plug end of the T6 adapter and plug the other end of the T6 cable into the back of the 6 button wall switch. Install the switch in the box and attach the cover plate. 7. Unplug the transformer located on the non-motor end of the screen. 8. Remove the receptacle cover plate. Install electrical hook up as shown in the wiring diagram. NOTE: Screen has been internally wired at Da-Lite. Wiring designated “external” is completed by installer conforming to local and national codes. 9. After the electrical connections are completed replace the cover plate and reinstall the transformer into the receptable. CAUTION! DO NOT CUT TAPE ON FABRIC WITH A KNIFE OR ANY SHARP TOOL. REMOVE BY PULLING TAB ATTACHED TO ORANGE STRING. 10. Carefully remove two wood boards securing mask surface to case. 11. Test installation by carefully running picture and mask surfaces up and down several times. Be prepared to stop screen. IMPORTANT. READ OPERATING INSTRUCTIONS BEFORE TESTING SCREEN. NOTE: When rolled down, the picture surface should wrap fully around the roller. No part of the roller should be exposed. Picture and mask surfaces will automatically stop in the down position. CAUTION! Excessive continuous operation may cause overheating. If this happens the motors will shut off until they cool to normal operating temperature. ▲! ▲! ▲! SCREEN ADJUSTMENT ADJUSTING THE SCREEN The motors on the Horizon Electrol® have been preset to four different screen formats based on your screen size. They are 1.33:1, 1.78:1, 1.85:1 and 2.35:1. It is possible to adjust these formats for your particular needs. 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.

1. Make sure the power is disconnected to the screen before starting. 2. Remove the cover plate from the wall switch, and then remove the switch from the box. 3. Unplug the T6 cable marked motor 2 from the T6 adapter. 4. Locate the bus interface control. It is located on the motor end of the screen case. Remove the screw that holds the cover shut. Slide the cover back and unplug the T4 wire marked motor 2. 5. Reconnect the power to the screen. 6. Press the button marked 1 to lower the screen. When the screen reaches the desired level press the stop button. 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. Press and hold in the chosen button for 5 seconds, then release. 7. The new stop position is now recorded for the selected button. Repeat this process for any other changes to the remaining 2 locations. 8. 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. MASK ADJUSTMENT (MOTOR 2) 1. Make sure the power is disconnected to the screen before starting. 2. Unplug the T4 cable marked motor 1 from the bus interface control. 3. Unplug the T6 cable marked motor 1 from the T6 adapter. 4. Reconnect the power to the screen. 5. Press the button marked 1 to lower the mask. When the mask reaches the desired level press the stop button. 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. Press and hold in the chosen button for 5 seconds, then release. 6. The new stop position is now recorded for the selected button. Repeat this process for any other changes to the remaining 2 locations. 7. 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. 8. Reconnect the T6 cable marked motor 1 to the 2-1, T6 adapter jack. 9. Reinstall the wall switch into the box and attach the cover plate. 10. Reconnect the power to the screen. 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. Below is a diagram of switch you will use. 1. Remove cover screw from bus interface unit located on the motor end of screen case. 2. Locate the T4 wires coming from the motors to the bus interface (see wiring diagram). 3. 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. 4. Locate the 3-position dipswitch in top right corner of switch. To adjust the down limit flip the switch in the down direction. Press and hold the 1 button on the switch to run the screen down to the desired position. Release the button to stop the screen. NOTE: If you push the down button and the screen runs in the up direction press and release the stop button. Then press the down button again. This should reverse the motor. 5. When the screen is at the desired location flip the dipswitch back in to the middle position. 6. To adjust the up limit (the screen should be in down position first) flip the dipswitch to the up direction. Press and hold the up button to run the screen to the desired top position. 7. When the screen is at the desired location flip the dipswitch to the middle position. Now press 1 button to make sure the screen stops at the new down position. Then press the up button and watch carefully to make sure it stops in the new up position. 8. Unplug the T4 wire from the switch and plug it into the SAME location you unplugged it from the bus interface unit.
