Changing the temperature scale
This thermometer is shipped with the Fahrenheit temperature
scale activated. If you wish to switch to Celsius (°C), proceed as
follows:
• Turn on the thermometer.
(If it is already turned on, make sure it is not in memory mode.)
• Press the /mem button and keep it pressed. Then press and
release the activation button to switch over to the «change
temperature scale» mode.
• By pressing the activation button again, the Celsius scale is
activated, «°C» is displayed on the LCD. Each further pressing
of the activation button toggles the scale between °C and °F.
• Release the /mem button to return to the ready symbol .
All temperatures stored in memory will automatically be converted
to the selected scale when displayed on the LCD.
Changing the lens filter
The thermometer is supplied with a lens filter in place. To assure
accuracy and sanitary practice, Braun recommends replacing the
lens filter after each use. To install a new lens filter, first remove
the one in place by pressing the lens filter ejector. Check the lens
for any damage. Then take a new lens filter from the box, and hold-
ing it by its edges, slide it onto the probe until it snaps in place.
Caution: Do not touch the tip of the probe or lens filters
when installing. Fingerprints, ear wax, dust and other soiling
compounds reduce the transparency, resulting in lower tem-
perature readings (see also Care and cleaning).
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.
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 ).
• Additional lens filters (LF 40 ) are available at most stores
