device in the cloth or wipe, but gently wipe the unit. Be careful not to let liquid pool around the display window
or other places. Allow the unit to air dry before use.
Special Cleaning Notes
Many vinyl gloves contain phthalate additives, which are often not recommended for medical use and are
known to be harmful to the housing of the ET1. The ET1 should not be handled while wearing vinyl gloves
containing phthalates, or before hands are washed to remove contaminant residue after gloves are removed. If
products containing any of the harmful ingredients listed above are used prior to handling the ET1, such as
hand sanitizers that contain ethanolamine, hands must be completely dry before handling the ET1 to prevent
damage to the plastics.
