Troubleshooting

When I press ON/OFF on the headset, the handset lifter is lifted, but the call is not connected or I do not hear a dial tone.

First try all the suggestions above.

When using the handset lifter, make sure LIFTER MODE is selected on the headset base and the telephone line cord is connected to the telephone line jack on the back of the corded phone.

The handset lifter may not be lifted high enough to release the switch hook. Try to adjust the height of the handset lifter by sliding the lifter arm height control up or down until it reaches the desired angle. Adjust the switch hook presser so that the switch hook is released when the lifter arm raises.

If you connect the telephone line cord to the TEL WALL JACK on the headset base while LIFTER MODE is selected, then you cannot make a call.

You should adjust the lifter audio first. During a call, slide the LIFTER AUDIO ADJUST on the side of the headset base from A to G until you obtain good sound quality.

If the previous suggestions don’t work, disconnect the telephone base from the telephone jack and connect a different phone. If there is no dial tone on that phone either, the problem is in your wiring or local service. Contact your local telephone company.

Your line cord might be malfunctioning. Try installing a new line cord.
