This warranty begins on the effective date of delivery to the end user. For your convenience, keep the original bill of sale as 
evidence of the purchase date.
Please fill out and mail your warranty registration card. It is imperative that Runco knows how to reach you promptly if we 
should discover a safety problem or product update for which you must be notified.
Repairs made under the terms of this Limited Warranty covering your Runco video product will be performed at the location of 
the product, during usual working hours, providing location of product is within normal operating distance from a Runco

Runco Authorized Service Center, or the repair requires the unit be returned to the Runco factory, it is the owner’s 
responsibility to arrange for shipment of the product for repair. These arrangements must be made through the selling Runco 
Dealer. If this is not possible, contact Runco directly for a Return Authorization number and shipping instructions. Runco will 
return product transportation prepaid in the United States, unless no product defect is discovered. In that instance, shipping 
costs will be the responsibility of the owner.

							vi Runco CL-420 Owner’s Operating Manual
Thank you for your purchase of this quality Runco video projector! It has been designed to provide you with the quality of video 
that is expected in a home theater. For the best performance, please read this manual carefully as it is your guide through the 
menus and operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC 
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Do not use this equipment near water, outdoors or otherwise exposed to the elements.
5. Clean only with a dry cloth.
6. Do not block any ventilation openings.
7. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that 
produce heat.
8. Do not defeat the safety feature of the polarized or grounding type plug. A polarized type plug has two blades with one 
wider than the other. A grounding type plug has two blades and a third grounding prong. The third prong is provided for 
your safety. If the provided plug does not fit into your outlet, consult an electrician for the replacement of the obsolete 
outlet.
9. The 12V trigger only outputs DC 12V signal for triggering. Do not connect to any other power input or output. This could 
cause damage to this unit.
10. Only use accessories specified by Runco International.
11. Keep the packing material in case the equipment should ever need to be shipped.
12. Unplug this projector during lightning storms or when it will not be used for an extended period of time.
13. The lamp becomes extremely hot during operation. Allow the projector to cool down for approximately 45 minutes prior to 
removing the lamp assembly for replacement. Do not operate lamps beyond the rated lamp life. Excessive operation of 
lamps beyond rated life could cause them to explode in rare occasions.
14. Refer all servicing to qualified service personnel. Servicing is required when the projector has been damaged in any way, 
objects have fallen or spilled into the projector, the projector has been exposed to rain or moisture, does not operate 
normally, or has been dropped.
