Batteries; Rf Interface; Operating Environment - Silvercrest Wireless Keyboard User Manual And Service Information

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. 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 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.
