The Italian Antitrust Authority has warned Cupertino, Calif.-based Apple Inc. that it could be slapped with more fines and have its Italian operations suspended if it doesn't comply with the country's two-year warranty policy.

Italy's ACGM competition authority said it could suspend Apple's Italian business operations for up to 30 days and impose a fine of up to _300,000 ($377,500) if the Cupertino firm doesn't clearly inform consumers about the various available warranty options.

The competition authority has accused the Cupertino firm of not only failing to tell consumers about the free deals, but also of selling them an AppleCare Protection Plan that offers similar coverage but charges a fee for that.

According to the Italian authority, Apple should have clearly explained to customers that it was obliged to offer a two-year warrantee for free.

Apple has already been slapped with a fine of _900,000 over the same warranty issue. Of the total fine, _400,000 was imposed for not offering the two-year warranty, while the remaining _500,000 for signing up customers to AppleCare Protection Plan.

Apple has been given 30 days to respond Italy's ACGM competition authority takes action against it.
