4.2 Cleaning and maintenance
• The sensor is the most sensitive part of the MEDISANA FTO
infra-red thermometer. Protect the lens from dirt and damage
by always putting the protective cap on the thermometer when
it is not in use.
• Should the lens get dirty, you can clean it carefully using the
alcohol wipes supplied with the unit. You may also use a cotton
bud soaked in alcohol or warm water to wipe the lens clean.
• Never use strong detergents or hard brushes.
• To clean the thermometer, please use a soft cloth moistened in
a mild soap solution. Do not let water get into the unit. Only use
the unit again when completely dry. However, if any liquid does
get into the unit, remove the battery immediately and discon-
tinue further use. In such a case, contact your dealer or the
MEDISANA Service Department.
• Do not use or store the unit in an environment where the
ambient temperature or humidity is too high or too low (see
operating conditions in the "Specifications" section) , in direct
sunshine, in the vicinity of static electricity or in a dusty en-
vironment.
• Remove the battery if you do not wish to use the unit for an
extended period of time, otherwise there is a risk of the battery
leaking.
• If the thermometer is used as described in these instructions, no
regular maintenance or calibration is required.
