If you are using an AC power supply, confirm that it is plugged in and the power outlet is turned on. Confirm that the headset/handset selector button is depressed (colored indicator showing). Confirm that the telephone handset cable and the short cord to the telephone are connected to the correct jacks (see Step 3). Confirm that the compatibility slider switch is in the correct setting for your telephone (see Step 5). You may want to try moving the switch through all of the positions until you hear a clear dial tone. I get a low pitched hum in my headset speaker and/or my callers complain they can hear hum. Try moving the telephone/amplifier compatibility slider switch through all of the positions until the hum disappears. I hear three `beeps' in the headset. My callers say that they can't hear me at all or they can't hear me very well. If you are using batteries to power the M140 Amplifier, three `beeps' tell you that the batteries are low and need to be replaced. See "Install Batteries" Step 2. Make sure the headset microphone is positioned in front of or near your mouth. If you are using a noise-canceling headset, the position of the microphone is very important. Then put it back on the silver stem of your headset.
