Troubleshooting
When I press on the headset, the handset lifter rises, but
the call is not connected or I do not hear a dial tone.
• Try all the suggestions above.
• When using the handset lifter, make sure the CORDED
HANDSET CONNECTED switch on the headset base is set to
YES and the telephone line cord is connected to the telephone
line jack on the back of the corded phone.
• The handset lifter may not rise high enough to release the
switch hook. Try to adjust the height of the lifter arm by
turning the ADJUST LIFTER knob until it reaches the desired
angle. Adjust the switch hook presser by turning the switch
hook presser adjustment knob so that the switch hook is
released when the lifter arm rises.
• If you cannot hear a dial tone when the headset is on, you
should adjust the quality of the corded handset audio first.
During a call, slide the corded handset audio adjust switch at
the bottom of the headset base from A to F 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 telephone. If there is no dial tone on that telephone
either, the problem is in your wiring or local service. Contact
your telephone service provider.
• Your line cord might be defective. Install a new line cord.
