covered with synthetic material,

the relative humidity should be at

least 30 %.

of the Digital Ear Thermometer

requires continued operation

during power mains

interruptions, it is recommended

that the Digital Ear Thermometer

be powered from an

uninterruptible power supply or a

battery.

Power frequency magnetic ﬁelds

NOTE 1 At 80 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.

a. 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 Digital Ear Thermometer is used

exceeds the applicable RF compliance level above, the Digital Ear Thermometer should be

observed to verify normal operation. If abnormal performance is observed, additional

measures may be necessary, such as reorienting or relocating the Digital Ear Thermometer.

b. Over the frequency range 150 kHz to 80 MHz, ﬁeld strengths should be less than 3 V/m.

RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF

(RADIO FREQUENCY) COMMUNICATIONS EQUIPMENT AND THE ME EQUIPMENT

OR ME SYSTEM

The Digital Ear Thermometer is intended for use in an electromagnetic environment in which

radiated RF disturbances are controlled. The customer or the user of the Digital Ear Thermometer can

help prevent electromagnetic interference by maintaining a minimum distance between portable

and mobile RF communications equipment (transmitters) and the Digital Ear Thermometer as

recommended below, according to the maximum output power of the communications equipment.

Rated maximum output

power of transmitter

For transmitters rated at a maximum output power not listed above, the recommended separation

distance d in meters (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 80 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.
