14 ECO (low-radiation) mode
•
This cordless telephone (compliant with the DECT standard) facilitates low-radiation
operation.
•
The radiation intensity of the radio signal between the base station and handset is
reduced to a minimum when the handset is on the base station.
•
Only when the handset is removed from the base station or a call is received does the
radiation intensity of the radio signal increase to the normal strength.
•
This does not mean that normal DECT radiation is harmful to health.
•
The low-radiation mode prevents unnecessary DECT radiation load when no
communication is required between the base station and handset.
•
For technical reasons, no additional handsets can be operated in low-radiation mode
(an additional handset that is not located in the immediate vicinity of the base station
would always be "searching for base station" due to the weak radio signal).
•
Low-radiation mode is enabled in the factory settings.
•
Low-radiation mode is automatically disabled if you log on an additional handset.
•
Low-radiation mode is automatically enabled again when you log off all additional
handsets (only one handset may be logged onto the base station).
•
The procedure for logging handsets on and off is explained in the User Manual.
