8107420 Rev. 6 67 03/09/2018
Guidance and manufacturer’s declaration — electromagnetic immunity
The touchTymp is intended for use in the electromagnetic environment specified below. The customer or the user of the touchTymp
should assure that it is used in such an environment,

used no closer to any parts of the
touchTymp, including cables, than the
recommended separation distance
calculated from 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 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 (b)
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 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 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 touchTymp is used exceeds the applicable RF compliance level above, the touchTymp should be
observed to verify normal operation, If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the touchTymp.
(b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
