How do I factory reset a Siemens Gigaset A580IP / C475IP / S685IP

To remove all settings from the phone (It will revert back to DHCP and a default pin of 0000).


  1. Remove the cables from the base station.
  2. Put the power cable back into the base whilst holding the blue button for 10 seconds.
  3. Once you release the button the base should be reset.
  4. Check which IP has been allocated by your DHCP server and configure in your browser.
