English

Batteries

Insert the batteries with the correct polarity. Never try to recharge the
batteries and under no circumstances throw them into fire. Do not mix battery
types (old and new or carbon and alkaline, etc.). Remove the batteries when
the device is not to be used for a long time. Improper use may cause
explosions and danger to life.

RF Interface

Turn the device off when onboard an aircraft, in a hospital, in an operating
theatre or in the vicinity of medical electronic equipment. The RF signals may
interfere with the functionality of sensitive devices. Place the device at least
20cm (8 inches) away from pacemakers, as the RF signals may interfere
with the functionality of the pacemaker. The transmitted RF signals can
cause interference with hearing aids. Do not place the device with the
wireless adapter turned on near flammable gases or in a potentially
explosive area (e.g. a paint shop), as the transmitted RF signals may cause
explosions or fire. The range of the radio wave signals depends on
environmental conditions. When data is transmitted via a wireless connection
it may also be received by unauthorized parties. Targa GmbH is not liable for
any interference caused to RF or TV signals through unauthorized
modification to this device. Furthermore, Targa does not assume any liability
for replacing any cables or devices that have not been specifically approved
by Targa GmbH. The user is solely responsible and liable for troubleshooting
any interference caused by unauthorized modification of this device and for
replacing appliances.
