Runco SC-1 用户手册

To help ensure optimized performance and reliability, check electrical, optical and other 
components regularly as described below. 

Do the following every 60 days or 500 hours of projector use: 

• Check the contact surfaces of the positive (anode) and cathode (negative) connections 

for cleanliness. Clean electrical contact surfaces as necessary to prevent contact 
resistance from scorching connectors. 

• Verify that all electrical and lamp connections are tight. 

Unnecessary cleaning of optics can be more harmful than helpful, increasing the risk of 
degrading delicate coatings and surfaces. In this projector, check only the lens and lamp 
reflector — maintenance of other optical components requires a qualified service 
technician. Check these components periodically in a clean, dust-free environment using 
a high-intensity light source or flashlight. Clean them only when dust, dirt, oil or other 
marks are obvious. Never touch an optical surface with your bare hand; always wear latex 
lab gloves. 

When to Check the Lens: A small amount of dust or dirt on the lens has minimal effect 
on image quality — to avoid the risk of scratching the lens, clean the lens only if absolutely 
required; see below. 

When to Check the Lamp Reflector: Inspect the mirror surface (reflector) for 
cleanliness only during a lamp replacement, when the lamp is out. If necessary, clean as 
described below. Always wear protective clothing while inspecting or cleaning. 
Note that color on the reflector surface may vary; this is normal. 

For cleaning off dust and/or grease, you will need: 

• Soft camel-hair brush. 

• Dust-free blower — filtered dry nitrogen blown through an anti-static nozzle. 

• Dust-free lens tissue: Melles Griot® Kodak tissues (18LAB020), Optowipes™ 

(18LAB022), Kimwipes® or equivalent. 

• Lens cleaning solution: Melles Griot Optics Cleaning Fluid 18LAB011 or equivalent (for 

lens only). 

• Methanol (for reflector only). 

• Cotton swabs with wooden stems only 

• Lens cleaning cloth/microfiber: Melles Griot 18LAB024 or equivalent.
