In this chapter, you will find important information on how to avoid life-threatening situations and how
to prevent product damage.
Data transmission
W
Warning
Danger due to possibly deficient data transmission.
WS unit operates using radio signals and cellular networks and is not authorized for use in safety-related
applications.
Deficient network coverage, failure or malfunction of the device may lead to deficient data transmission.
Because of this, connection cannot be guaranteed at all times under all conditions.
•
Do not operate the device in machines and applications where life depends on the proper operation
of this piece of equipment.
•
Never rely solely upon any wireless device for essential communications.
Health care facilities
W
Warning
Danger of interference caused by RF energy. Medical equipment may be sensitive to RF energy.
•
When in a hospital or other health care facility, observe the restrictions on the use of cellular
communication equipment.
•
Switch WS unit off, if instructed to do so by the guidelines posted in sensitive areas.
•
The operation of cardiac pacemakers, other implanted medical device and hearing aids can be
affected by interference from WS unit's antennas placed close to the device.
•
If in doubt about potential danger, contact a physician or the manufacturer of the implanted medical
device to verify that it is properly shielded.
•
Pacemaker patients are advised to keep WS unit and its antennas away from the pacemaker while it is
on.
Air traffic communications
W
Warning
Danger of interference caused by RF energy. The operation of wireless appliances in an aircraft is
forbidden to prevent interference with communications systems. Failure to observe these instructions
may lead to the suspension or denial of cellular services to the offender, legal action, or both.
1. Switch off WS unit before boarding an aircraft.
2. Make sure it cannot be switched on inadvertently.
Explosive areas
W
Warning
Danger of explosion. The device does not comply with Directive 94/9/EC and must therefore not be used
in potentially explosive areas.
•
Observe the applicable regulations and precautions when you are near explosive areas (such as
petrol stations, fuel depots, chemical plants or where blasting operations are in progress).
•
Do not mount the antenna in the close environment of fuel tanks, vessels with explosives and
insufficiently shielded electronic devices.
