Headset base and handset lifter installation
Adjust the corded handset audio
After you have connected the headset base
to your corded phone, you may need to
adjust the corded handset audio switch at
the bottom of the headset base for optimal
sound quality.
To adjust the corded handset audio:
Lift the corded handset and then
press on the headset to check for a
dial tone. If there is no dial tone or the
dial tone is unclear, slide the corded
handset audio switch at the bottom of
the headset base from

to
F
until the
dial tone is clear.
