Frequently Asked Questions - DS 22 Veroval

How to choose between ear and forehead measurement?

Use the mode selector located on the side of the thermometer. The ear symbol (👂) indicates ear mode, the forehead symbol (👀) indicates forehead mode. Ear measurement is recommended for optimal accuracy, forehead measurement is convenient and non-invasive.

Is a protective cap needed for forehead measurement?

No, no cap is necessary for forehead measurement. Only use the provided forehead attachment. Do not place an ear cap on the forehead attachment, as this would distort the measurement.

How to interpret the fever indicator?

After a measurement, if the temperature is below 37.6 °C, the indicator lights up green. If it is above or equal to 37.6 °C, it lights up red, signaling potential fever.

What to do if the screen displays 'Hi' or 'Lo'?

'Hi' means the measured temperature exceeds 43 °C, 'Lo' means it is below 34 °C. Check the correct placement of the thermometer and that the lens is clean. If the problem persists, contact customer service.

How to clean the thermometer?

Clean the measuring tip and sensor after each use with a soft cloth or cotton swab dampened with 70% alcohol (isopropanol) or disinfectant. Do not use aggressive solvents. Wait for complete drying before a new measurement.

How many measurements can be taken with the supplied batteries?

The supplied high-performance AAA batteries allow approximately 1,000 measurements. Use batteries of the same type for replacement.

Can I use the thermometer on a child under 6 months?

Ear measurement is not recommended before 6 months because the ear canal is too narrow. Forehead measurement can be used, but ensure the child has been in a room at ambient temperature for at least 30 minutes.

How to access stored measurements?

Turn on the thermometer with the SCAN button, then press the M button. The screen displays the most recent measurement with date and time. Press M again to cycle through the last 10 values.

What to do in case of error 'Er 2' or 'Er 3'?

'Er 2' indicates instability: repeat the measurement following the instructions. 'Er 3' signals a malfunction: remove and reinsert the batteries. If the error persists, contact customer service.

Is the thermometer waterproof?

No, the thermometer is not waterproof. It is protected against water splashes (IP22) but should not be immersed. Avoid any direct contact with water or other liquids.

Recommended separation distances between portable and mobile RF communications equipment and the Veroval® DS 22
The Veroval® DS 22 is intended for use in an electromagnetic environment in which radiated therefore disturbances are controlled. The customer or the user of the Veroval® DS 22 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the device as recommended below, according to the maximum output power of the communications equipment.

0.1 0.38 0.73
1 1.2 2.3
10 3.8 7.3
100 12 23
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.NOTE 1 At 8- MHz and 800 MHz, the separation distance for the higher frequency range applies.NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
