Cleaning and storage
• The sensor lens is the most delicate part of the thermometer and should be
kept clean at all times.
• To do this, only use a soft cloth or cotton bud with a little water or medical
alcohol.
• Allow the lens to fully dry before using the thermometer.
• Wipe the other parts of the thermometer regularly with a moist, lint-free cloth. Do
not use alcohol or solvents.
• Do not submerge the thermometer in water or any other liquid.
• There are no user-serviceable parts.
• Contact your dealer for spare parts if necessary.
• The thermometer should be stored between –20°C to +65°C (-4°F to +149 °F).
