Error Message; Care And Cleaning - Braun WelchAllyn ThermoScan Mode D'emploi

If the thermometer shows «RET» (without the battery symbol) on its display, the

by mode.

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 affected by damage to the probe window, or
the presence of dirt or cerumen on the probe window.
To assure a high level of accuracy, it is very important to keep this window clean,
dry and undamaged. Fingerprints, cerumen, dust and other soiling compounds
reduce transparency of the window and result in lower temperature measure-
ments. 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 moist-
ened with isopropyl 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 isopropyl alcohol to clean the probe
window.
Thermometer
Use a soft cloth slightly moistened with isopropyl alcohol to clean the thermome-
ter display and exterior. As needed, clean the thermometer and probe with a 70%
isopropyl alcohol solution or a 10% chlorine bleach solution or a nonstaining
disinfectant such as CaviCide
Never submerge the thermometer in water or any other liquid. Store thermometer
and probe covers in a dry location (the thermometer is not protected against in-
gress of water), 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 50 °F to 104 °F (10 °C to 40 °C).
