The "Dial Tone Detection" test failed

Solution:

•Other equipment, which uses the same phone line as the device, might be causing the test to fail. To find out if other equipment is causing a problem, disconnect everything from the phone line, and then run the test again. If the Dial Tone Detection Test passes without the other equipment, then one or more pieces of the equipment is causing problems; try adding them back one at a time and rerunning the test each time, until you identify which piece of equipment is causing the problem.

•Try connecting a working phone and phone cord to the telephone wall jack that you are using for the device and check for a dial tone. If you do not hear a dial tone, contact your telephone company and have them check the line.

•Make sure you have correctly connected the device to the telephone wall jack. Using the phone cord supplied in the box with the device, connect one end to your telephone wall jack, then connect the other end to the port labeled 1-LINE on the back of the device.

•If you are using a phone splitter, this can cause faxing problems. (A splitter is a two-cord connector that plugs into a telephone wall jack.) Try removing the splitter and connecting the device directly to the telephone wall jack.

•If your telephone system is not using a standard dial tone, such as some PBX systems, this might cause the test to fail. This will not cause a problem sending or receiving faxes. Try sending or receiving a test fax.

•Check to make sure the country/region setting is set appropriately for your country/region. If the country/region setting is not set or is set incorrectly, the test might fail and you might have problems sending and receiving faxes.

•Make sure you connect the device to an analog phone line or you will not be able to send or receive faxes. To check if your phone line is digital, connect a regular analog phone to the line and listen for a dial tone. If you do not hear a normal sounding dial tone, it might be a phone line set up for digital phones. Connect the device to an analog phone line and try sending or receiving a fax.

•Make sure you use the phone cord that came with the device. If you do not use the supplied phone cord to connect from the telephone wall jack to the device, you might not be able to send or receive faxes. After you plug in the phone cord that came with the device, run the fax test again.

After you resolve any problems found, run the fax test again to make sure it passes and the device is ready for faxing. If the Dial Tone Detection test continues to fail, contact your telephone company and have them check the phone line.
