I cannot dial out
in LIFTER MODE.
My corded
phone is ringing,
but I do not hear
the call alert
tone.
• First try all the suggestions above.
• Make sure you have a dial tone before
dialing. The corded handset or headset
may take a second or two to find the
telephone base and produce a dial tone.
This is normal. Wait an extra second
before dialing.
• Make sure LIFTER MODE is selected on
the headset base.
• Make sure the ring detector is pushed
all the way into the plug on the handset
lifter.
• If the ring detector is not installed, there
are no audio and visual alerts of incoming
calls on the headset.
• Make sure the ring detector is installed
close to the speaker of your telephone.
• Make sure that the
the lifter is on. If the
is off, there are no call alert tones in the
headset.
• It may be necessary to adjust the
sensitivity of the ring detector. See
page 12 for instructions.
• Make sure all cords and the telephone
line cord are plugged into the appropriate
outlets.
• Make sure your headset is charged.
