Guidelines
Portable and mobile RF
communication equipment shall not
be used closer to any part of this
medical infrared thermometer than the
recommended isolation distance,
including cables. The distance shall be
calculated by a formula corresponding
to the frequency of the transmitter.
Recommended isolation distance:
Formula:
p — according to the maximum rated
output power of transmitter provided
by transmitter manufacturer, in watts
(W);
d — Recommended isolation distance,
in meters (m), b.
The field strength of the fixed RF
transmitter is determined by surveying
the electromagnetic field C. in each
frequency range, d should be lower
than the compliance level.
Interference may occur near
equipment marked with the
following symbols.

Note 1: on the frequency of 80MHz and 800MHz, the formula of higher frequency band should
be adopted.
Note 2: these guidelines may not be applicable to all situations. Electromagnetic coupling is
affected by absorption and reflection of buildings, objects and human body.
a.
Fixed transmitters, such as base stations for wireless (cellular / cordless) telephones and
ground mobile radios, amateur radios, am and FM radio broadcasts, and television
broadcasts, are theoretically unpredictable in field strength. To evaluate the electromagnetic
