Appendix Ⅰ Maintenance
Attention:
Please maintain the device according to the following instructions in order to ensure the image
effect and long-term stable operation of the device.
Maintenance for lens and mirror surface
The lens and mirror surface are covered with antireflection coating, so it may produce
hazardous substance and lead to performance reduction or scratch, dimness etc when it is
stained with dust, grease, fingerprint and so on, please refer to the following methods to deal
with once dirt is found:
Stained with dirt
Use oil-free soft brush or hair dries to remove it gently.
Stained with grease or fingerprint
Use soft cloth to wipe the water drop or oil gently to make it dry, then use oil-free cotton cloth
or paper soaked with alcohol or detergent to wipe from the lens center to outward. It is ok to
change the cloth and wipe several times if it is not clean enough.
Camera Body Maintenance
Use a soft dry cloth to clean the camera body when it is dirty, in case the dirt is hard to remove,
use a clean dry cloth soaked with mild detergent and wipe gently, make it dry later. Don’t use
volatile solvent like alcohol, benzene, thinner and etc or strong detergent with abrasiveness,
otherwise it will damage the surface coating or reduce the working performance of the device.
Maintenance for Dome Cover
Dome cover is an optical device, please don’t touch or wipe cover surface directly during
installation and use, please refer to the following methods to deal with once dirt is found:
Stained with dirt
Use oil-free soft brush or hair dries to remove it gently.
Stained with grease or fingerprint
Use soft cloth to wipe the water drop or oil gently to make it dry, then use oil-free cotton cloth
