Error Code 21

  • This error generally occurs when the cradle is in an office and plugged into a phone system that runs on a higher voltage.
  • An office phone system can damage the cradle.
  • The best option is to plug the cradle's phone line into a jack on a dedicated FAX line or take the cradle home if you have normal phone lines there.

  • Email the webmaster with suggestions.
