DM110i™, DM160i™, DM220i™ (PR20)


When connected via telephone line, the meter displays the error message No Dial Tone or No Carrier Detected when attempting to add funds, perform a data capture upload, or a system update.

Note: This article is for meters connected via telephone line only.  If your meter is not connected via phone (for instance, uses SmartLink™ or the Pitney Bowes Communication Device), please see How to resolve "No Dial Tone" message when meter is not connected to phone line.


This error is most often caused by the franking machine not being able to hear a dial tone on the phone line it is connecting through.

We recommend that you switch to a digital connection: SmartLink™ connects your meter to your LAN (Local Area Network) via an ethernet cable or WiFi.  It enables you to add postage and perform data uploads with speed and ease, as well as access postage rates and software updates automatically by connecting your franking machine digitally to Pitney Bowes.

You may be able to resolve the issue by restarting the meter, then retrying a connection.

If the problem persists, to troubleshoot your connection you will need an analogue telephone in order to test the phone line.
  1. Connect the telephone to the socket the meter is connected to.
  2. If you do not hear a dial tone, check that the telephone cable is not faulty.
    • If possible, test with another telephone cable.
    • If you still do not hear a dial tone, the line is not active and this is the source of the problem.  Try connecting the telephone to another port, or contact your IT or telephone provider.
  3. If you can hear a dial tone, dial 08719480102.
    • If you need to dial a number to get an outside line (usually 9 or 0), this "prefix" also needs to be set on the meter.  To check that the correct prefix is stored on the meter, see How to add or remove the dialling prefix.
    • If you do not hear a fax tone, contact your IT or telephone provider.
  4. Restart the meter by unplugging the power cable for 10 seconds, then replace it.
  5. Connect the telephone line at the back of the meter.  (If possible, use the one that was just used to test the telephone line.)
  6. If the meter displays Data Upload Required, select Connect Now. Otherwise, press the Add Postage key and select Check PbP Balance to attempt a connection.
