Troubleshooting
• If you are using a handset lifter, 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 the good sound quality is obtained.
The other party
cannot hear my
voice during a
call.
• When the handset lifter is used, make sure
LIFTER MODE is selected on the headset
base and the headset is in use (pressing
ON/OFF on the headset and the
LIFTER MODE light on the headset base
flashes). Slide the LIFTER AUDIO ADJUST
on the side of the headset base from
A to G until the dial tone is clear.
Nothing happens
when I move the
LIFTER AUDIO
ADJUST switch.
