Belmont PROIII 047, Инструкция по эксплуатации, Страница: 34 / 36

Recommended separation distances between Portable and mobile RF communications equipment and the
PROIII 047.
The PROIII 047 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the PROIII 047 can help prevent electromagnetic interference by main-
taining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
PROIII 047 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 800MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by adsorption
and reflection from structures, objects and people.

8. Essential performance
Unless operated by the switches for chair control, the PROIII 047 does not
make any movements, except for sounding a buzzer and switching on/off
the indicator.
