During initial setup of a Power Macintosh G3, after selecting a country a dialog box may appear informing you to call Apple regarding the modem even though the computer does not have a modem.

The dialog box shown below is generated during the initial setup of Mac OS where it would normally set the country code for the modem. This issue affects only the first production run of Power Macintosh G3 computers without modems, and is not an indicator of any flaw with your computer.

Simply click OK and proceed; you do not need to contact Apple support for assistance.
