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

100 12.0 12.0 23.0
For transmitters rated at a maximum output power not listed above, the recommended
separation distance in metres (m) can be estimated using the equation applicable to the
frequency of the transmitter where 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
a󰀨ected by absorption and reection from structures, objects and people.
