Portable and mobile RF communications
equipment should be used no closer to
any part of the TH30F, including cables,
than the recommended separation

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
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic
site survey, a should be less than the
compliance level in each frequency range

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
affected by absorption and reflection from structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM to fixed RF transmitters,
an electromagnetic site survey should be considered. If the measured field strength in the
location in which the TH30F is used exceeds the applicable RF compliance level above,
the TH30F should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the
TH30F.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
The TH30F is intended for use in the electromagnetic environment specified below.
The customer or the user of the TH30F should assure that it is used in such an environment.
