Recommended separation distances between portable and mobile RF communications
equipment and the Valon or Valon TT
The Valon and Valon TT are intended for use in an electromagnetic environment in which radi-
ated RF disturbances are controlled. The customer or the user of the Valon or Valon TT can
help prevent electromagnetic interference by maintaining a minimum distance between port-
able and mobile RF communications equipment (transmitters) and the Valon or Valon TT as
recommended below, according to the maximum output power of the communications equip-
ment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
metres (m) can be estimated using 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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reection from structures, objects and people.
