Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The ACTitouch System is intended for use in the electromagnetic environment specified below. The
customer or the user of the ACTitouch System should assure that it is used in such an environment.

Electromagnetic environment — guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the
ACTitouch System, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance
Conducted RF

d = 0.35 √P
Radiated RF

3 V/m
d = 0.29 √P 80 MHz to 800 MHz
d = 0.58 √P 800 MHz to 2.5 GHz
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 metres (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 80MHz and 800MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflected from structures, objects, and people.
NOTE 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 ACTitouch device is used exceeds the applicable RF compliance level above, the ACTitouch System
should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating ACTitouch System.
NOTE B Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
