Manufacturer’s declaration-electromagnetic immunity
The TH8xyz series is intended for use in the electromagnetic environment specified below.
The customer or the user of the TH8xyz series should assure that it is used in such an environment.

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 TH8xyz series is used exceeds the applicable RF compliance
level above, the TH8xyz series should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating
the TH8xyz series.
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.
