Polaroid Polaview 220 - Manual (Page 32)

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).
