EQUIPMENT AND SYSTEMS
The model
BW-BT1
is intended for use in the electromagnetic environments specified below. the
customer or the user of the model
BW-BT1
should assure that it is used in such an environment.

RF emissions
CISPR 11
Group 1
The
BW-BT1
use RF energy only for its internal function. There-
fore, its RF emisssions are very low and are not likely to cause any
interference in nearby electronic equipment.

The
BW-BT1
is suitable for use in all establishments other than
domestic and those directly connected to the public low-voltage
power supply network that supplies buildings used for domestic
purposes.

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 with
the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be con-
sidered. If the measured field strength in the location in which the location in which type
BW-BT1
is used exceeds the applicable RF compliance level above, the
BW-BT1
should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the
BW-BT1
.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between portable and mobile RF communications
equipment and the equipment and
BW-BT1
. The
BW-BT1
is intended for use in an elec-
tromagnetic environment in which radiated RF disturbances are controlled.
