Maintenance and storage
1. Wipe and clean all glass components with gauze. In order to remove fingerprints or other oil stains,
use a very small amount of 2 parts of ether + 1 part of ethanol mixture solution as cleaning agent, wet
the gauze and wipe it gently.
Ether and ethanol are extremely flammable and must be handled with care. Be careful not to put these
chemicals near open flames and possible sources of spark, such as switches. Be sure to use it in a well ventilated
room.
2. For the non optical parts of the device, do not use organic solvent to wipe, but clean cloth can be
used. If it is very dirty, please use a soft cloth with a small amount of neutral detergent to wipe.
3. Do not disassemble any part of the device arbitrarily, or it may cause failure or reduce performance.
