Common Macintosh Errors / Solutions
Error 680: There is no dial tone
This page applies to Mac OS 9 users only.
If your modem cannot find a dial tone, make certain that all of your phone line connections going in and out of the modem are tight and secure, and then try to connect to NetZero again. If nothing changes, then one of the solutions below should help:
A. Verify your modem settings
If your modem is not configured correctly, NetZero will not function properly. To verify that your modem configuration is correct, please complete the following steps:
- Go to the Apple Menu, select Control Panels and choose Modem.
- In the Modem window, choose your modem from dropdown menu (Such as Apple Internal 56K Modem)
- Change the Sound and Dialing preferences as needed.
- Make sure the box next to Ignore dial tone is NOT checked.
- Go to the File menu and select Quit. If you are asked to save your changes, click Yes.
B. Check that your modem is connected properly
Please verify that a telephone cord is connected from the wall jack directly into your Macintosh's modem port.
If you have other devices connected between the wall jack and the modem (such as fax machines, caller id boxes, or other phones), then these could be interrupting the dial tone. Try disconnecting all other devices - this may resolve the problem. You can then connect the devices to a different wall jack.
C. Disable other programs that may be using your modem
It is possible that a program running in the background, may be locking your modem (such as fax and voicemail software, or another ISP's software). To work around this problem, disable all programs running in the background by following these steps:
- Check and see what programs are running by clicking the application menu in the upper-right corner of the Finder.
- Select a program on the list (preferably a fax / modem program) to switch to that application, then quit it by going to the File menu and selecting Quit.
- Try your NetZero connection again. If this does not resolve the problem, close NetZero. Repeat Steps 1 and 2, quitting one program at a time. Each time you quit a program, try your NetZero connection again. When you stop receiving the error, the last program you quit is likely the one creating the conflict.
- Once you've found the conflicting program, close it before you logon to NetZero. You can contact the manufacturer to see if they have more information about a solution so you can use both NetZero and this program at the same time.
