Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment
due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the
Model Number or Type Number - by manufacturer is used exceeds
the applicable RF compliance level above, the Model Number or Type
Number - by manufacturer should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Model Number or Type

Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than [Vi] V/m.

1. Algemene beschrijving
De Contactloze Infrarood Voorhoofdthermometer is speciaal ontworpen
om de lichaamstemperatuur van personen te meten, ongeacht de
omgevingstemperatuur. Afhankelijk van verschillende huidtypes en
-diktes kan er een temperatuurverschil zijn.
2. Veiligheidsinformatie
• Dit apparaat mag alleen worden gebruikt voor de doeleinden die
worden beschreven in deze gebruikershandleiding.
• Dit apparaat mag alleen worden gebruikt bij een
omgevingstemperatuur tussen 10°C en 40°C.
• Stel deze thermometer niet bloot aan elektrische schokken.
• Stel deze thermometer niet bloot aan extreme temperaturen van
>50° C of <0°C.
• Gebruik het apparaat niet bij een relatieve luchtvochtigheid van meer
dan 85%.
• Gebruik het apparaat niet in de buurt van grote elektromagnetische
velden, zoals bij draadloze apparaten of mobiele telefoons.
• Houd het apparaat uit de buurt van water en hitte, inclusief direct
zonlicht.
• Laat het apparaat niet vallen, stoot het niet en gebruik het niet als het
beschadigd is.
• De nauwkeurigheid van metingen kan beïnvloed worden wanneer
het voorhoofd bedekt is met haar, een muts of sjaal of bij transpiratie.
(Zie 10-4)
• Zorg ervoor dat de meetafstand tussen de 1 en 10 cm ligt. (Zie 10-4)
• De thermometer dient zich ten minste 15 tot 20 minuten vóór gebruik
te bevinden in de ruimte waar de meting zal plaatsvinden.
• Wanneer er zich transpiratie op het voorhoofd bevindt of het voorhoofd
bedekt is, kan dit de nauwkeurigheid van metingen beïnvloeden. Neem
in dat geval de temperatuur achter de oorlel op. (Zie 10-5)
