RF emissions CISPR 11 Group 1 The FT65 Multi-function Thermometer uses RF energy only for its internal
function.
Therefore, its RF emissions are very low and are not
likely to cause any interference in nearby electronic equipment.

the transmitter manufacturer and d is the recommended separation distance in meters

Interference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption and reection from
structures, objects and people.
Field strengths from xed transmitters, such as base stations from radio (cellular/cordless) telephones and land mobile radios, ama-
teur radio, AM and FM radio broadcast and TV broadcast can not be predicted theoretic call with accuracy. To assess the elec-
tromagnetic environment due to xed RF transmitters, an electromagnetic site survey should be considered. If the measured eld
strength in the location in which the FT65 Multi-function Thermometer is used exceeds the applicable RF compliance level above, the
FT65 Multi-function Thermometer should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the FT65 Multi-function Thermometer.
Over the frequency range 150kHz to 80MHz, eld strengths should be less than [V1] V/m.

The FT65
Multi-function
Thermometer is intended for use in an electromagnetic environment in which radiated RF distances are con-
trolled. The customer or the user of the T FT65
Multi-function
Thermometer can help prevent electromagnetic interference by maintain-
ing a minimum distance between portable and mobile RF communications equipment (transmitters) and the FT65

mometer 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 distanced 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 trans-
mitter 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 aected by absorption and reection from
