AT&T Tech Support 客户常见问题解答

You can troubleshoot a static issue on your TR1909 Trimline phone by following these steps: 1. Unplug all equipment from your phone jacks, including modems, fax machines, and cordless phones. Leave them unplugged for a few minutes. 2. Plug your Trimline phone directly into the phone jack. If you don't hear any static, the problem was likely with one of the other devices. 3. If you still hear static, switch to a different phone cord. The problem might be with the original cord. 4. If you're still experiencing issues, the problem could be with your wall jack or wiring. If none of these steps work, you might need professional assistance to inspect and repair your line.
