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 WiTouch or
WiTouch
Pro is used exceeds the applicable RF compliance level above, the WiTouch or WiTouch
Pro should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the WiTouch or
WiTouch
Pro.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances
between portable and mobile RF communications equipment and the WiTouch and WiTouch

The WiTouch and WiTouch
Pro are intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the WiTouch or WiTouch
Pro can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the WiTouch or WiTouch
Pro as recommended below, according to the
maximum output power of the communications equipment.
