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.). Batteries must never be opened or deformed. Otherwise there is a risk of leaking chemicals. If
the chemicals become in contact with your skin or eyes, rinse with plenty of fresh water immediately
and seek medical aid. 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. Keep 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 accepts no liability for replacing any
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.
