Braun ThermoScan IRT 1020 - Manual (Page 9)

Care and cleaning Lens Tip
• The lens tip is the most delicate part of the
thermometer. It is covered with a soft, thin
membrane which forms a surface that is
transparent to heat waves. To ensure
accuracy, it is very important to keep the
lens clean and intact, and to always keep a
clean, new lens filter attached. Fingerprints,
ear wax, dust and other soiling compounds
reduce ransparency of the lens, resulting in
lower temperature readings. Remember:
always store the thermometer in its cover
when not in use.
• Inspect the lens whenever you replace a
lens filter. To clean the lens, very gently
wipe the surface with a cotton swab or soft
cloth moistened with alcohol or mild soap
and warm water (Figure 11). After cleaning,
allow at least 45 minutes drying time before
reattaching a lens filter and taking tem-
peratures. If the lens is damaged, contact
Braun.
Lens Filters
• Replace lens filter after each use. Make
sure that the new lens filter is not damaged.
• Keep lens filters out of direct sunlight and
ultraviolet light for extended periods of time.
Store lens filters away from dust and
contamination.
Thermometer
• Use a soft, dry, clean cloth to clean the
instrument display and exterior. Do not use
abrasive cleaners of submerge in water or
other liquids.
• This instrument contains precision
components and should not be subjected to
extremes in temperature, humidity, direct
sunlight, shock or dust.
• Store unit in a location where the
temperature remains fairly constant and
within the range of 16°C to 40°C (61°F to
104°F). To ensure that the Braun
ThermoScan Thermometer is always ready
to take a temperature (and avoid Err 4),
store it in the room where it is most
frequently used.

• If temperatures appear to be reading low, ensure proper technique is
being used (see page 11 to 12). Make sure the lens is clean and a new
lens filter is attached.
• If temperatures appear to be reading high, be sure a new lens filter is
attached. Inspect the lens; if it is damaged, the thermometer must be
serviced.
• To assure accuracy and sanitary practice, Braun recommends
replacing the lens filter after each use. Should you run out of lens filters
and need to take a temperature, you may use the following lens filter
cleaning procedure: Clean the lens filter without removing it from the
thermometer with a soft cloth or cotton swab moistened with alcohol or
mild soap and water. Do not use hot or boiling water. Dry completely with
a soft cloth before reusing. Replace lens filter as soon as possible with
a new one (LF 40).
LCD-Display Situation Solution
The activation button was
pushed sooner than 8
seconds after the previous
activation. The countdown in
seconds will also appear
until another temperature
can be taken. Wait until the display
shows
(ready) before
taking another
temperature.
Flashing
The battery power is getting
low. There is enough
remaining power for about
10 days or 10 temperatures. Install a fresh battery.
Constant
The battery is so low that no
more temperatures can be
taken. Install a fresh battery.
