3. DISINFECTION PROCEDURE
Turn the device off and disconnect the power cord from mains before proceeding with the
disinfection.
3.1 Disinfecting the front lens
Wipe the front lens using photographic cleaning paper (e.g. Edmund Optics NT53-984) or a
single-use microfiber cloth soaked in pure Isopropyl alcohol. Press lightly the wet cloth on the front
lens surface. Starting from the center of the lens, wipe it with a circular movement, very slowly, only
for one complete rotation. The exiting movement (i.e. moving away from the lens) has to be made
radially, towards the border. Do not reuse the wiping cloth after one pass.
Allow the lens to dry.
3.2 Disinfecting all other parts
Disinfect the parts listed below using Isopropyl alcohol (solution >70%).
Do not pour the disinfectant directly on the device, instead use a disposable towel to apply it.
•silicone chin rest and forehead rest (do not remove them before disinfecting);
•plastic covers, including the back panel of the tablet, the patient button and any cables;
•any aluminum parts;
•screen;
•rear panel (see Fig. 2);
Allow all surfaces to dry before turning on the device again.
The device name printed on the plastic covers is not meant for frequent
disinfections and may degrade if the process is repeated many times.
The front lens is not meant for frequent disinfections and its anti-reflective
coating may be permanently damaged if the process is repeated many times.
