Electromagnetic
environment—guidance
Linepower quality should be that
of a typical commercial or
hospital environment. If the user
of the Transcend Auto requires
continued operation during
power line interruptions, it is
recommended that the
Transcend Auto be powered from
the battery.

where P is the maximum output
power rating of the transmitter
in watts (W) according to the
transmitter manufacturer and
is the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site survey,
should be less than the
compliance level in each
frequency range.
Interference may occur in the
vicinity of equipment marked
