Care and cleaning
Braun ThermoScan probe covers are intended for single use only! To
ensure accurate readings, always use Braun ThermoScan disposable
probe covers with the Pro 4000 thermometer. Damaged, perforated,
or soiled probe covers can lead to inaccurate temperature readings.
Additionally, the accuracy of your temperature readings can be af-
fected by damage to the probe window, or the presence of dirt and ear
wax on the probe window.
Probe Window
To assure a high level of accuracy, it is very important to keep this
window clean, dry and undamaged. Fingerprints, earwax, dust and
other soiling compounds reduce transparency of the window and
result in lower temperature readings. If the thermometer is accidentally
placed in the ear without a probe cover installed, the window must be
cleaned immediately. Additionally, the window and/or probe tip area
should never be modified, changed, or adjusted. These changes will
affect calibration and accuracy of the thermometer.
To clean the window, gently wipe its surface with a cotton swab slightly
moistened with alcohol and immediately wipe dry with a clean cotton
swab. After cleaning, allow at least 5 minutes drying time before taking
temperatures. Make sure probe window is clean and dry. Avoid
touching the window except when cleaning is required. If the window
is damaged, the thermometer must be returned to Welch Allyn for
service.
Note: Do not use any chemical other than alcohol to clean the probe
window.
Thermometer
Use a soft cloth slightly moistened with alcohol to clean the thermo-
meter display and exterior. Do not use abrasive cleaners. Never sub-
merge the thermometer in water or any other liquid.
Store thermometer and probe covers in a dry location free from
dust and contamination and away from direct sunlight. The ambient
temperature at the storage location should remain fairly constant and
within the range of 10 °C to 40 °C ( 50 °F to 104 °F ).
