Cleaning the carrying case

Refer to the following to clean the projector case.

  1. Wipe off dust with a clean dampened cloth.  
  2. Moisten the cloth with warm water and mild detergent (such as used to wash dishes), and then wipe the case. 
  3. Rinse all detergent from the cloth and wipe the projector again.

Special note for ultra-short throw projectors for reflection mirror cleaning.

The mirrors on the UST projectors are sensitive optical devices made of vapour deposition silver. Touching it directly can cause damage to the mirror, and the mirrors needs to be handled with care. Do NOT under any circumstances use detergents and any sort of cloths to wipe the mirrors. Instead, use an air bellow or compressed air to clean the mirror from dust.

 

In the event that the mirror has fingerprints or other substances that are not possible to remove with air, we recommend that the unit is brought in for service to an authorized service centre for cleaning by a professional repair technician. Cost will apply if the mirror has been scratched or damaged due to fingerprints or other substances.
