Device Symbols
Electromagnetic Environment
This device has been tested and found to comply with the limits for medical devices
to the IEC/EN 60601-1-2. These limits are designed to provide reasonable protection
against harmful interference in a typical medical installation. However, because of
the proliferation of radio-frequency transmitting equipment and other sources of
electrical noise in healthcare environments (for example, electrosurgical units,
cellular phones, mobile two-way radios, electrical appliances, and high-definition
television), it is possible that high levels of such interference due to close proximity
or strength of a source may result in disruption of performance of this device. This
Digital Infrared Thermometer is not designed for use in environments in which the
pulse can be obscured by electromagnetic interference. During such interference,
measurements may seem inappropriate or the monitor may not seem to operate
correctly.
Warning:
Digital Infrared Thermometer should not be used adjacent to or
stacked with other equipment and that if adjacent or stacked use is
necessary, Digital Infrared Thermometer should be observed to
verify normal operation in the configuration in which it will be used.

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

considered. If the measured field strength in the location in which the model IRT101B/IRT101
is used exceeds the applicable RF compliance level above, the model IRT101B/ IRT101
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the model

The model IRT101B/IRT101 is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of the
model IRT101B/IRT101 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the model IRT101B/IRT101 as recommended below,
according to the maximum output power of the communications equipment.
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 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
