DANGER! Please make sure that
the device is checked prior to use. Never use a faulty or damaged device,
the receiver is never touched with wet hands; there is a risk of electric shock,
the receiver is disconnected from the mains network prior to cleaning, otherwise there is a risk of
electric shock,
the receiver is never immersed in water; there is a risk of electric shock,
the receiver is protected from dripping or splashing water,
there are no naked flames (for example, burning candles) placed on or near the device.
DANGER! Operational safety
Only connect the receiver to a freely accessible power socket so that it can be quickly disconnected
from the mains in the event of danger (smoke, smell of burning). The power socket must be easily
accessible at all times, also during operation.
As soon as the receiver is connected to the mains network, it starts receiving power. Even when the
device is not in use, it consumes minimal power. Disconnect the receiver from the mains network if the
device is not being used for prolonged periods. This minimises the risk of a fire or smouldering, which
always exists when an electrical device is connected to the mains network. To fully disconnect the
receiver from the mains network, the plug must be pulled from the power socket.
Do not use any adapter plugs or extension cables that are damaged or do not meet the relevant
safety standards.
Never open the housing of the receiver. There is a danger of death due to risk of electric shock when
the housing is open.
The receiver must never be covered, as this poses a fire hazard caused by overheating,

Electrical devices must be kept out of the reach of children. Also, people with restricted physical, mental
or sensory abilities should only use electrical devices be appropriate to their capacity. Never leave
children or people with disabilities unattended with electrical devices, unless they have been instructed
on their use or will be supervised by a person responsible for their safety. Children should generally be
supervised to ensure they do not play with this device. Cleaning and user maintenance must not be
carried out by children. Small parts can be lethal if swallowed. Keep the packaging film away from
children. Packaging materials are not to be played with.

DANGER! Batteries
Always insert batteries with the correct polarity. When doing so, observe the labels on the batteries and
in the battery compartment. Do not try to recharge batteries and never throw them onto a fire. Do not
use different batteries (old and new, alkaline and carbon etc.) at the same time. Remove the batteries if
you intend not to use the device for a longer period of time. There is a risk of explosion and leakage if
the device is not used properly.
Batteries must not be opened or deformed in any way because leaking chemicals can cause injury. If the
batteries have leaked, remove them to avoid damaging the device. You can remove leaked battery

DANGER! Wireless interface
Do not use the device if you are on a plane, in a hospital, operating room or in the vicinity of a medical
electronic system. The radio waves transmitted can damage the functioning of sensitive devices. Keep
the device at least 20 cm away from a pacemaker or an implanted defibrillator, as otherwise the correct
functioning of the pacemaker or implanted defibrillator could be impacted by radio waves. The radio
waves transmitted can cause static noise in hearing aids. When wireless components are switched on,
do not place the device in the vicinity of flammable gases or in a potentially explosive environment (e.g.
paint shop), as the radio waves transmitted can trigger an explosion or a fire. The range of the radio
waves depends on the setting and ambient conditions. When transmitting data via a wireless
connection, it is also possible for unauthorised third parties to receive this data. Targa GmbH is not
responsible for wireless or radio interference caused by unauthorised changes to this device.
