Manufacturer’s guide and declaration - Electromagnetic emissions
The scale W1090 is intended for use in the electromagnetic environment speci-
fied below. The customer/user should assure that it’s used in that environment.

Equipment in RF communications
and mobile laptops should ot be
used near any part of the tooth,
including cables, except when
they meet the recommended se-
paration distance calculated by
the frequency applied to the tran-
smitter. Recommended separa-
tion distance d = 1.2 √ P d = 1.2 √ P
from 80 MHz to 800 MHz d = 2.3 √
P from 800 MHz to 2.5 GHz where
the P and maximum rated power
output of the transmitter in Watts
(W) according to the manufactu-
rer of the transmitter and the re-
commended separation distance
in meters (m). The intensity of the
field of a fixed RF transmitters, as
determined by an electromagnetic
site, it could be lower than the le-
vel of compliance of each range of
frequency b. You can check inter-
ference in proximity of equipment
marked with the following symbol:

With 80 MHz and 800 MHz is applied the higher frequency range. These guidelines
may not apply in all situations. Electromagnetic propagation is affected by absorp
-
tion and reflection from structures, objects and people.
a)
The intensity of the field for fixed transmitters such as base stations for radiote
-
lephone mobile and cordless phones) and land radio mobile, amateur radio equi-
pment, radio transmitters in the AM and FM and TV transmitters cannot be made
theoretically and with precision. To establish an electromagnetic environment due
to fixed RF transmitters, it should consider the electromagnetic survey of the site.
If the field strength measured at the place where you use the device, exceeds the
applicable level of compliance of the above, it should be placed under observation
normal operation of the tooth. If you notice abnormal performance, it may take
additional measures as a different orientation or position of device.
b)
Over the frequency range from 150 kHz to 80 MHz should be less than 3 V / m.
