Cleaning Procedure — Exterior.
To clean the analyzer exterior, do the following
steps:
1. Remove loose dust on the outside of the analyzer with a lint free cloth.
2. Remove remaining dirt with a lint free cloth dampened in a general purpose
detergent-and-water solution. Do not use abrasive cleaners.
3. Clean the light filter protecting the monitor screen with a lint-free cloth
dampened with either isopropyl alcohol or, preferably, a gentle, general
purpose detergent-and-water solution.
CAUTION.
To prevent getting moisture inside the analyzer during external
cleaning, use only enough liquid to dampen the cloth or applicator.
