What should I do if the handset A420 is switching off and on again during incoming or outgoing calls?

If you have activated the Eco-Mode+ on your base and your handset is switching off and on again during an incoming or outgoing call you should go through the following procedure:

Handset in idle mode 

  •  Press Menu key
  •  Enter *#7337#
  •  Enter 07733 07417 51974
  •  Confirm with OK
  •  Press Menu key
  •  Enter *#7337#
  •  Enter 23349 23032 26631 
  •  Confirm with OK
  •  Press Menu key
  •  Enter *#7337# 
  •  Enter 24373 24019 24364 
  •  Confirm with OK

 

After confirming with OK you will see the display message “Saved”.

If there is a display message “Invalid” you have entered a wrong number and you must go through the whole procedure again.
