If the user of the
Keratron™ requires
continued operation during power mains
interruptions, it is recommended that the
Keratron™ uninterruptible power suplí or a

Portable and mobile RF communications
equipment should be used no closer to any
part of the
Keratron™, including cables,
than the recommended separation distance
calculated from he equation applicable to
the frequency of the transmitter.
Recommended separation distance:
d= 1.2 ÖP
d= 1.2 ÖP 80MHz to 800 MHz
d= 2.3 ÖP 800MHz to 2.5 GHz
where
P
is the maximum output power
rating to 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,
