Gigaset 620A handset freezes.
It only affects the main handset. The others work fine. I fix it by removing the battery and replacing it. Is there a permanent fix?
the Gigaset series have an inbuilt service menu that can be accessed to get additional software or hardware information or to enable the survey mode to do a DECT survey with just a phone instead of the survey kit.
To enable it:
1. Power it off
2. Press 1 – 4 – 7 while powering it on
3. Enter the code 76200
