Chapter 5 Taking Care of Your Qumi
Cleaning the Qumi
Cleaning the Qumi to remove dust and grime will help provide trouble-free operation.
Warning:
1. The Qumi should be turned off and unplugged before cleaning. Failure to do so may
result in injury or damage to the system.
2.
Use only a dampened cloth when cleaning. Do not allow water to enter the ventilation
openings on the Qumi.
3. If a small amount of water gets into the interior of the Qumi while cleaning, unplug the
Qumi and set in a well ventilated area for several hours before using.
4. If a large amount of water gets into the interior of the Qumi when cleaning, unplug the
Qumi and have it serviced.
Cleaning the Lens
Optical lens cleaning solutions can be purchased from most camera and other retail
stores. To clean the Qumi lens, perform the following steps:
1. Apply a small amount of the optic lens cleaning solution to a clean and soft cloth. (Do
not apply the cleaning solution directly to the lens.)
2. Gently wipe the lens in a circular motion.
Caution:
1. Do not use abrasive cleaners or solvents.
2. To prevent discoloration or fading, do not allow the cleaning solution to contact the Qumi
case.
