Troubleshooting
If the headset’s volume level drops or if the phone begins to make
unusual sounds, determine if other phones on the same line have
been picked up. In areas with low telephone voltage, the ET-153
might not operate when other phones are active on the same line.
Hanging up the other phones should correct the problem.
If you still have problems, immediately disconnect the ET-153. If oth-
er phones on the same line operate normally, the fault is in the ET-
153 or its installation. If you are unable to locate the problem, take
the ET-153 to your local RadioShack store for assistance.
