User information

3.1

Important notes

Important information on copyright, liability and
warranty provisions, as well as on equipment users
and company obligations, can be found in the separate
manual "Important notes on and safety instructions
for Bosch Test Equipment". These instructions must
be carefully studied prior to start-up, connection and
operation of the BEA 750 and must always be heeded.
3.2

Safety instructions

All the pertinent safety instructions can be found
in the separate manual "Important notes on and
safety instructions for Bosch Test Equipment". These
instructions must be carefully studied prior to start-up,
connection and operation of the BEA 750 and must
always be heeded.
3.3

Wireless link (Bluetooth and WLAN)

!
BEA 750 users are responsible for compliance with
the applicable directives and restrictions in the
country concerned.
Important information on WLAN and Bluetooth
WLAN (Wireless Local Area Network) is the term used
to describe a wireless local network. Bluetooth and
WLAN provide a radio link on the free 2.4 GHz ISM band
(ISM: Industrial, Scientific, Medical). This frequency
range is subject to state legislation, can however be
used without a license in most countries. Consequently
a large number of applications and devices employ
this frequency band for transmission. This can result in
frequency interference and faults.
Depending on ambient conditions, the radio link may
deteriorate, e.g. in the case of Bluetooth links, cordless
telephones, radio-controlled thermometers, radio-
controlled garage door openers, radio-controlled light
switches or radio-controlled alarm systems.
i
Bluetooth can cause bandwidth collapse in the
WLAN network. The antennas of Bluetooth and
WLAN devices should be at least 30 centimeters
apart. Use the USB extension cable (special
accessory) to maintain a distance between the
Bluetooth USB adapter on the PC/laptop and the
WLAN antenna.
i
Extreme caution is to be taken if wearing
pacemakers or other vital electronic devices when
using wireless systems, as proper functioning of
these items could be impaired.

Pay attention to the following to ensure the best
possible connection:
¶
The radio signal always tries to find the most direct
path. When setting up the PC/laptop and access
point, make sure there are as few obstacles as
possible (e.g. steel doors and concrete walls) which
could interfere with the signal from and to the
BEA 750.
¶
Inside buildings, the range of the WLAN / Bluetooth
is also greatly influenced by the construction
materials used. Conventional masonry, wooden
walls and various types of dry construction wall
scarcely impair the propagation of radio waves.
Thin gypsum walls are however problematic, as
considerable amounts of moisture may accumulate
in the gypsum and result in the absorption of radio
signals. Metal walls and concrete (in particular
reinforced concrete) largely block out radio waves.
Cellar ceilings are often impenetrable. Generally
speaking, walls with a lot of installed metal (e.g.
pipes, cables) obstruct radio waves.
¶
Radio reception is also impeded by large metal
objects such as radiators and window frames as
well as active sources of interference such as radio
telephones, motion detectors and microwave ovens.
¶
Human beings are also an obstacle to wireless
transmission. It must therefore always be ensured
that no-one stands between the transmitter and
receiver.
¶
We advise having the network infrastructure
installed and maintained by a network specialist.
¶
When using a WLAN connection, keep the SSID and
the codes for the wireless link in a safe place. Make
sure these data are readily to hand in case faults
occur.
¶
When commissioning, we recommend that you
tour the site thoroughly: Determine where in your
building BEA 750 functions and where the limits for
wireless transmission are located.
¶
The wireless link is affected by weather conditions.
The reception signal may therefore vary.
¶
Please contact your network specialist for any
queries.
¶
In the event of problems with the Bluetooth link, the
USB link can be activated and used instead of the
Bluetooth connection.
