Cleaning the workstation case
●
Follow the safety precautions presented in
Service considerations on page 52 before cleaning the
workstation.
●
To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
●
For stronger stains, use a mild dish-washing liquid diluted with water. Rinse well by wiping it with
a cloth or swab dampened with clear water.
●
For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed because the alcohol will
evaporate quickly and not leave a residue.
●
After cleaning, always wipe the unit with a clean, lint-free cloth.
●
Occasionally clean the air vents on the workstation. Lint and other foreign matter can block the
vents and limit the airflow.
