Cleaning, Maintenance and Service

13. Cleaning, Maintenance and Service
To maintain the life of the components and the accuracy of the instrument,
regular maintenance is required in the form of lubrication and cleaning.

Routine Hygiene and Cleaning

All surfaces coming in contact with patients need regular disinfecting.
Standard instrument grade disinfectant like IPA (Isopropylalcohol) diluted
with 50% water may be used on all external surfaces. Wipe surfaces with a
damp cloth only to avoid liquid entering delicate parts and optics. Do not use
strong oxidising agents or solvents as they could damage surface coatings. Do
not use any aerosols or sprays that could contaminate the optics. Use soft non-
abrasive cloth only. Special care of the inside of the cone is required, and is
described in the section below.

Cleaning of contaminated Optics

The following optics are externally accessible and subject to contamination
from dust, residues from evaporated liquids, body acids and fats, and makeup.

Cone surface.

Imaging lens front surface.

Profile illumination window (on RH channel just inside cone edge).

Profile image window (on LH channel inside cone edge).
Internal optical surfaces are not accessible without disassembly. Do not
attempt to disassemble or turn any of the sealed mounting screws, as the
alignment of the optics and the calibration may be altered considerably. Do
not put any objects into the cone other than those listed.
Recommended cleaning materials:

Cotton tips. For Profile windows preferred tapered cotton tips

Micro fibre cleaning cloth or lint free lens paper

Non-smear optics cleaner or diluted IPA
The cone assembly is made of polymer products. This means the cone is
sensitive to mechanical surface damage (scratches, dents) and may not be
chemically resistant to certain solvents.
Do not use any abrasive cloth or strong organic solvents like acetone.
The image lens is positioned near the apex of the cone and difficult to access.
Unless the optical performance of the lens is noticeably affected we do not
recommend approaching the lens. Dust on this surface is not visible on the
