For your safety
SX682 WiMAX / engbt / SX682_FUG_EN_9 / Safety.fm / 17.5.11
Schablone 2011_04_07
For your safety
Please read the safety instructions carefully before putting into service.
Safety precautions
General safety instructions
If you give the SX682 WiMAX to someone else, make sure you also give them its
documentation.
The SX682 WiMAX must only be used as described in these installation instruc-
tions.
Safety instructions for connection
Only use the mains adapter supplied, as indicated on the underside of the SX682
WiMAX.
Safety precautions for the SX682 WiMAX
The operation of medical appliances may be affected. Be aware of the technical
conditions in your particular environment, e.g. doctor's surgery.
The SX682 WiMAX and the antenna can interfere with the functioning of medical
devices such as pacemakers. Keep at least 20 cm between the devices and the
pacemaker. For more information, consult your doctor.
The device may cause an unpleasant humming noise in hearing aids.
Do not use the devices in environments with a potential explosion hazard, e.g. car
paint shops, or in a humid environment (bathroom etc.).
The Ethernet function (LAN socket, LAN) and the FXS function (analogue phone
port, Phone) are designed exclusively for connection inside a building.
Cleaning and care
Wipe the SX682 WiMAX with a damp cloth (do not use solvent) or an antistatic cloth.
Never use a dry cloth. This can cause static.

Information on Specific Absorption Rate (SAR)
SX682 WiMAX / engbt / SX682_FUG_EN_9 / Safety.fm / 17.5.11
Schablone 2011_04_07
Information on Specific Absorption Rate (SAR)
This device meets the limits for protecting the health of the public from the effecs of
exposure to electromagnetic fields when it is operated in connection with the desig-
nated antenna(s) like described in the user manual.
Your device is a radio transmitter and receiver. It is designed and manufactured not to
exceed the limits for exposure to emission from electromagnetic fields recommended
by international guidelines from the International Commission on Non-Ionizing Radia-
tion Protection (ICNIRP). These limits are part of comprehensive guidelines for the pro-
tection of the public and establish permitted levels of exposure to electromagnetic radi-
ation for the population. The guidelines were confirmed by independent scientific
organisations through periodic and thorough evaluation of scientific studies. The limits
include a substantial safety margin designed to assure the safety of all persons, regard-
less of age and health.
The exposure limit employs a unit of measurement known as the Specific Absorption
Rate, or SAR. The SAR limit stated in the international guidelines is 2.0 W/kg. Tests for
SAR are conducted in all frequency bands with the device transmitting at its highest
power level with minimum possible distance to the body. The actual SAR level of the
device during operation with the designated antenna(s) is below the maximum value
and is additionally decreased by a distance to the device. This is because the device is
designed to operate at multiple power levels so as to use only the power required to
enable seamless network connection.
Information about the optional outdoor antenna
Wall duct:
To connect the SX682 WiMAX to the outdoor antenna, the antenna cable must be fed
through the wall to the outside of the building. It must be possible to make a suitable
wall or window duct at or near the location of the SX682 WiMAX.
Only one of the antennas listed on page 13 must be used.
The outdoor antenna must be installed and put into service by a qualified
electrician.
Only commence the outdoor work once you have taken all the nec-
essary steps to make the location safe.
Be sure to observe the safety instructions.

Setting up the antenna mast:
There should not be any obstructions (walls, trees etc.) in front of the antenna.
The antenna mast must be structurally secure. Check how secure the various attach-
ments are.
The antenna mast must be within reach of the cable. Ideally, the antenna cable should
be protected outside (from frost, sun, unauthorised and mechanical influences etc.).
In particular, make sure the antenna mast has sufficient load capacity. If you are mount-
ing the mast on the roof, make sure the roof is fully sealed again afterwards.
Lightning protection
The antenna mast should be positioned near a lightning conductor. A suitable lightning
conductor must be installed where necessary.
The outdoor antenna is not designed to be struck directly by lightning and must be pro-
tected accordingly. The antenna must therefore be mounted in areas that are protected
against lightning (Lightning Protection Zone 0B). The corresponding separation dis-
tance (IEC 62305) must be complied with.
Earthing and lightning protection work may only be carried out by electricians specifi-
cally qualified for such work.
The best results will be obtained if the outdoor
antenna is in sight of the WiMAX base station
(cf. Fig. 1).
If a line of sight is not possible, you can reflect the
radio waves off neighbouring buildings. To do
this, direct the antenna at the building it is to
reflect off and not at the base station (cf. Fig. 2).

SX682 WiMAX / engbt / SX682_FUG_EN_9 / Safety.fm / 17.5.11
Schablone 2011_04_07
The appropriate earthing clamps must be used to create an equipotential bonding
between a cable shield and an equipotential bonding bar that complies with regula-
tions.
Please observe the standard DIN VDE 0855-300 and find out more on the Internet at
http://www.dehn.de.
Antenna cable and antenna connection:
It must be possible to connect the outdoor antenna to the SX682 WiMAX by means of
an antenna cable.
Please note that the antenna connection must be protected from the impact of rain and
other weather effects.
Use cable clamps to attach the cable to the mast. Please note that the cable must be
long enough to turn the antenna at a later stage.
Antenna alignment:
When aligning the antenna, we recommend asking a second person to run the Basic
Setup Wizard on the PC and to check the reception quality on the screen; see Chapter
"Basic Setup Wizard" on page 27.
After installation:
Tighten all screw connections to the torques listed in the installation instructions.
Secure the antenna cable with cable clamps and cable ties. The cable must be pro-
tected from exposure to pressure and tension.
i
Aligning the antenna using acoustic signals
If neither you nor the assistant are able to check the signal strength on
screen while the antenna is being aligned, you can monitor it via a radio
system. To do this you will need, for example, two cordless phones,
mobile phones or radio devices:
Activate Tone on on the configuration PC.
Establish an internal connection between the two handsets and
switch on the loudspeaker on both devices.
Leave one handset next to the configuration PC and carry the other
with you (belt clip).
You will now be informed of the signal strength by means of beeps. The
closer together the sequence of beeps, the better the connection quality.

The connection quality can be detected in two different ways:
CINR (Carrier to Interference and Noise Ratio) measures the signal
quality.
RSSI (Received Signal Strength Indication) measures the signal
strength.
The LEDs indicate either RSSI or CINR values. The used method is pre-
configured by your operator. If RSSI is used the RSSI 1 - RSSI 4 LEDs
will show the signal strength.
