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