preventive inspection
1）Cosmetic inspection
Check if there is any looseness or dislocation of the equipment switch and connector
socket, if there is any oxidation, rust or bad contact of plugs and sockets, and if there is any
aging of power cords. If any, please replace it in time.
2) Cleaning and maintenance
Chin rest and forehead rest
Swab them with 75% medical alcohol to clean and sterilize every day before use. Before
use, put the disposable chin rest paper for each patient.
Optical device
Any pollution at the positioning window may result in failure to recognize or
align the center between eyes, which may lead to measurement error, or even failure to
measure; please dip neutral detergent with the clean cotton swab to clean the external surface
of positioning window.
Touch screen
Clean the display with soft lint-free cloth. In case of any stain that cannot be removed
completely, please dip some water to wet the soft cloth.
Other external surface
Other external surface of equipment can be cleaned with soft lint-free cloth wetted with
little water.
Cleaning cycle
It is suggested to clean the whole equipment every two months. Clean the optical devices
only when they are dirty.
Notes:
Since optical devices are easily damageable, they cannot be wiped frequently, and the
operators shall try to avoid contacting the optical surface directly with objects during use.
Patience and technical skills are required for cleaning optical devices, and please contact
after-sales service person or professional person in case of any doubt about cleaning.
Protect the equipment from water during the cleaning. Lint-free cloth can be wetted but
free from any drops. Prevent any fluids flowing into the equipment.
3) Safety inspection
Check if the chin rest is installed firmly, and if the 3D movement system works well;
check if there is any looseness, fall-off or rupture of connecting pieces. If any, please contact
our company or authorized dealers.
