Any portable or mobile radio
frequency communication
equipment shall not be used in
a distance closer to any part of
E6 Emergency Ventilator
(including cable) than as
recommended. Such distance
is determined based on a
formula related to transmitter
frequency.
Recommended Distance
d =
: the maximum rated output
power (in Watt) of transmitter
provided by its manufacturer;
d
: the recommended distance
(in meter)
b
.
The field strength of fixed radio
frequency transmitter is
determined based on the
survey at EMI location
c
, and
each frequency range should
be lower than Compliance
Level
d
.
Interference may occurs near
the equipment attached with
the following signs.
Note 1：
For frequency of 80MHz and 800MHz, a formula in respect of high frequency should be
used.
Note 2：
As EM transmission is affected by absorption and reflection of buildings, objects and
human bodies, these guidelines may not be applicable to all circumstances.
a) ISM bands between 150kHz and 80MHz are 6.765MHz~6.795MHz,
13.553MHz~13.567MHz, 26.957MHz~27.283MHz and 40.66MHz~40.70MHz.
b) ISM bands between 150kHz and 80MHz and compliance levels between 80MHz and
