Maintenance
- Cleaning: To clean the telephone, wipe it with a soft, dry cloth. For stubborn marks, a slightly damp cloth can be used, followed by a dry cloth. Do not use abrasive cleaners, solvents, or strong chemicals, as these may damage the surface.

Troubleshooting
If you experience issues with your Jacob Jensen T-1 telephone, please refer to the following common troubleshooting steps:
-
No Dial Tone:
- Ensure the telephone line cord is securely connected to both the telephone and the wall jack.
- Check if other telephones on the same line are working. If not, there might be an issue with your telephone service.
- Verify the tone/pulse dialing switch is set correctly for your service type.
-
Cannot Make or Receive Calls:
- Confirm the telephone line connection is secure.
- If you can make calls but not receive them, or vice-versa, ensure the handset is properly seated in the cradle when not in use.
- Test with another telephone if available to determine if the issue is with the T-1 unit or the telephone line.
-
Poor Call Quality (Static, Low Volume):
- Check the telephone line cord for any damage.
- Ensure the volume settings are adjusted appropriately.
- Interference from other electronic devices can sometimes affect call quality. Try moving the phone or other devices.
If these steps do not resolve the issue, please contact your retailer or a qualified service technician.
