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.
