Guidance and manufacturer’s declaration – elecromagnetic immunity
Valon and Valon TT are intended for use in the electromagnetic environment specified below.
The customer or the user of Valon and Valon TT should assure that it is used in such an envi-
ronment.

equip-ment should be used no closer to any
part of Valon or Valon TT 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 metres
(m). Field strengths from fixed RF transmit -
ters, as determined by an electromagnetic
site survey, a should be less than the compli-
ance level in each frequency range. b Inter-
ference may occur in the vicinity of equip-
ment marked with the following

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 af-
fected by absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) tel
-
ephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To as-sess the electromagnetic environment
due to fixed RF transmitters, an electromagnetic site survey should be considered. If the meas -
ured field strength in the location in which Valon or Valon TT are used exceeds the applicable
RF compliance level above Valon or Valon TT should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorient-
ing or relocating the Valon or Valon TT.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
