EMC data
Guidance and manufacturer’s declaration - electromagnetic immunity - for equip-
ment and system that are not life-supporting. The model BW-CX10 is intended for
use in the electromagnetic environment specied below. The customer or the user of
the model BW-CX10 should assure that it is used in such an environment.

a. Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be consid-
ered. If the measured eld strength in the location in which the Infared Thermometer type
BW-CX10 is used exceeds the applicable RF compliance level above, the Infared Thermome-
ter type BW-CX10 should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as reorienting or relocating the
Infared Thermometer type BW-CX10.
b. Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3V/m.
Recommended separation distances between portable and mobile RF communications
equipment and the equipment or system - for equipement and systems that are not
life-supporting. The model BW-CX10 is intended for use in an electromagnetic environ-
ment in which radiated RF disturbances are controlled. The customer or the user of the
model BW-CX10 can help prevent electromagnetic interference by maintaining a mini-
mum distance between portable and mobile RF communications equipment (transmitters)
and the model BW-CX10 as recommended below, acording to the maximum output power
of the communications equipment.

For transmitters rates 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 transmit-
ter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800MHz, the reparation distance for the higher frequency range
applies.
