Set the dial-tone detection
Normally, the product begins dialing a fax number immediately. If you are using the product on the same line as your telephone, turn on the detect-dial-tone setting. This prevents the product from sending a fax while someone is on the telephone.
The factory-set default for detect dial tone is On for France and Hungary, and Off for all other countries/regions.
