away from sources of excessive heat (radiators, direct sunlight, etc.) and protected against vibrations and dust. Never allow

optimize reception, take particular care to keep it away from the immediate vicinity of windows, large metal objects, reinforced
concrete, televisions, music centers, halogen lamps or heating devices, fluorescent lighting, burglar alarms, microwave ovens,

In the event of danger, the mains adapter acts as 230V power isolating device. It should therefore, as a precaution, be installed
close to the appliance and be easily accessible.
If the mains adapter fails, it must be replaced by an identical model.
If not connected to the mains power or if there is a mains power failure, installations with cordless handsets will no longer
work. You will then be unable to make or receive calls in the event of an emergency. This is why we recommend that you also
have a conventional telephone as a backup. The appliance is designed for connection to an analogue telephone line class TRT3
(telecommunications network voltage).
! Do not use your telephone to notify a gas leak when you are in the vicinity of the leak.
It is recommended that you avoid using this device during electrical storms.
Thomson Telecom hereby declares that the 21878 conforms to the essential requirements and other applicable provisions of
European directive 1999/5/CE.

case the power in your home goes out.
