Portable and mobile RF
communications equipment should be
used no closer to any part of the Dr
Trust Instascan Forehead & Ear
Thermometer-606 including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
d=2.3 P 800MHz to 2.5MHzHere P is
the maximum output power rating of
the transmitter in watts (W) according
to the transmitter manufacturer and d
is the recommended separation
distance in meters (m). Field strengths
fo r m xe d R F t ra n s m i t te r s, a s
determined by an electromagnetic
site survey, should be less than the
compliance b level in each frequency
range. Interference may occur in the
vicinity of equipment marked with
the following symbol:
d=1.2 P 80MHz to 800MHz
NOTE 1 At 90MHz and 800MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and re ection from structures, objects and people.
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 considered. If the measured eld strength in the location in which the
Dr Trust Instascan Forehead & Ear Thermometer-606 is used exceeds the applicable RF
compliance level above, the Dr Trust Instascan Forehead & Ear Thermometer-606 should
be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the Dr Trust
Instascan Forehead & Ear Thermometer-606.
Table 8
The Dr Trust Instascan Forehead & Ear Thermometer-606 is intended for use in an
electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the Dr Trust Instascan Forehead & Ear Thermometer-606 can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Dr Trust
Instascan Forehead & Ear Thermometer-606 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 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 80MHz and 800MHz, 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 re ection from structures, objects and people.
