Mains power quality should be that of a typical commercial or hospital
environment. If the user of the 6500] requires continued operation
during power mains interruptions, it is recommended that the 6500 be
powered from an uninterruptible power supply or a battery.

Portable and mobile RF communications equipment should be used no
closer to any part of the 6500, including cables, than the recommended
separation distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d = 1,2
d = 1,2 80 MHz to 800 MHz
d = 2,3 800 MHz to 2,5 GHz
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 transmitters, as determined by an
electromagnetic site survey,a should be less than the compliance level
in each frequency range.b
Interference may occur in the vicinity of equipment marked with the
following symbol:
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 6500 is used exceeds the
applicable RF compliance level above, the 6500 should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the 6500.
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 6500
The 6500 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the 6500 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the 6500 as recommended below,
according to the maximum output power of the communications equipment.
