4 Maintenance
Storage, cleaning and care
Store the Polaview Model 220 Projector either in its original shipping container or carrying case to guard it against dust and lint. Use a non-abrasive, lint-free cloth and non-abrasive cleaning solution, such as an eyeglass or camera-lens clean- ing solution, on the lens to keep it clean. Spray the cleaning solution directly on the cleaning cloth, never on the lens.
Warning: Always disconnect your projector from its electri- cal supply before performing any maintenance on it.
Extreme temperatures Do not expose the projector to temperatures less than -13°F (-25°C) or greater than 140°F (60°C). For example, avoid storing it in parked automobiles for an extended period of time. Do not operate the projector in temperatures less than 32°F (0°C) or greater than 95°F (35°C).
