If the thermometer shows «RET» (without the battery symbol) on its display, the anti-theft
time has elapsed and the thermometer must be returned to the station for unlocking.
If the anti-theft function is not enabled, the display will show «off» when in stand-by mode.

Care and cleaning

Braun ThermoScan probe covers are intended for single use only!
To ensure accurate measurements, always use Braun ThermoScan disposable probe covers
with the Pro 4000 thermometer. Damaged, perforated, or soiled probe covers can lead to
inaccurate temperature measurements. Additionally, the accuracy of your temperature meas-
urement can be affected by damage to the probe window, or the pres-ence of dirt or cerumen
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, cerumen, dust and other soiling compounds reduce transparency of
the window and result in lower temperature measurements. 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 ad-
justed. 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 (the thermometer is not protected
against ingress 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).
