8. Cleaning and maintenance of the device

The measuring sensor is the most important and most sensitive part of the device. In order to ensure
most precise measurements, it always has to be clean and intact.
Clean the measuring tip and the sensor exclusively with the Soft-Zellin alcohol swabs supplied along
with the device or with a soft moist cloth or with 70 percent alcohol (isopropanol). Residues from
earwax can be removed carefully using cotton buds. Please do not use any aggressive cleaning
agents or solvents as they may damage the device and could make the display intransparent. Please
make sure that no fluid can penetrate the interior of the thermometer. To protect it from external
influences keep the thermometer in the storage box.

9. Power supply and disposal notes

9.1 Batteries and disposal

The two high-quality batteries included with the device guarantee at least 1,000 measurements.
Use only high-quality batteries (see specification in Chapter 14 "Technical data").
If you are using less efficient batteries, we can no longer guarantee 1,000 measurements.
Never mix old and new batteries or batteries made by different manufacturers.
Immediately remove exhausted batteries.
If you do not intend to use the device for a longer period of time, you should remove the batteries
to prevent possible leakage.
Please help protect the environment: Do not dispose of batteries in household waste! Use
designated collection points or municipal collection / recycling centres to dispose of hazardous
household waste.
This symbol on products and/or accompanying documents means that spent electronic
products must not be mixed with regular household waste.

9.2 Battery replacement

This device has been provided with two alkaline batteries of LR03 (AAA) type. Please replace spent
batteries by two new LR03 batteries as soon as the following battery symbol is indicated in the
display: .
Open the battery cover in the direction of the arrow on the rear side of the device by applying gentle
pressure on the notch. Now insert the two "AAA" size batteries so that the positive (+) and negative
(–) polarities match the "+" and "–" signs shown on the marking in the battery compartment. If the
polarities do not match, the device will not work and the batteries may leak! Replace the lid of the
battery compartment, applying gentle pressure until the hook snaps in place. The last measured
value recorded in the memory will not be lost when changing the batteries.

10. Error messages

Thermoval duo scan is a clinically validated, high-quality product. Nonetheless error messages may
occur, such as in the case of excessively high or low ambient temperature, if the measuring
temperature is outside the range for human body temperatures, if the batteries are empty or in very
rare cases, if a system error occurs. The description of errors is provided at the end of these
instructions for use along with the explanation of the symbols on the display.
