Guidance and manufacturer’s declaration - electromagnetic emissions
The TH1002 is intended for use in the electromagnetic environment specified below.
The customer or the user of the TH1002 should assure that it is used in such an
environment.

RF emissions
CISPR 11
Group 1 The TH1002 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.

Recommended separation distances between
portable and mobile RF communications equipment
and the ME EQUIPMENT or ME SYSTEM
The TH1002 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the TH1002 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the TH1002 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 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.
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.

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 TH1002 is used exceeds the applicable RF compliance level above,
the TH1002 should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the TH1002.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
