When I press ON/OFF (TL7610/TL7612) or (TL7810/TL7812/
TL7910/TL7912) 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 that TL7610/
TL7612 headset base is set to LIFTER MODE, or the CORDED
HANDSET CONNECTED switch is turned to YES on the
TL7810/TL7812/TL7910/TL7912 headset base. Make sure 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 LIFTER AUDIO ADJUST switch at the
side of the TL7610/TL7612 headset base from A to G, or the
LIFTER AUDIO ADJUST switch at the bottom of the TL7810/
TL7812/TL7910/TL7912 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 telephone service.
Contact your telephone service provider.
• Your line cord might be defective. Install a new line cord.
