Headset
My headset is unstable. When you wear the headset, the microphone should rest as close to your
cheek as possible without touching. The microphone can be adjusted inward
by pivoting the earpiece to optimise the position of the headset. See
Position
your headset .
Talk time performance
is significantly degraded
even after a full recharge. Battery is wearing out. Call Plantronics at (800) 544-4660 for ordering a
replacement battery or contact us at
plantronics.com/support .
Desk phone
I can’t hear a dial tone in
the headset. Make sure your headset is charged.
Make sure your headset is subscribed to base. See
Subscription button .
Press the call button on your headset.
If using a lifter, make sure the lifter is lifting the handset high enough to
operate the hookswitch; set to a higher setting if necessary.
Adjust the configuration switch on the base until a dial tone is heard.
Fine-tune the listening volume on the headset.
If the volume is still too low, adjust the listening volume dial on the base.
I hear static. Make sure there are at least 12 inches between your base and your computer,
and 6 inches between your base and your telephone. You may hear static as
your headset is going out of range; move closer to the base.
The sound is distorted. Lower the speaking volume dial or listening volume dial on the base. For
most telephones, the correct setting is position 3.
If your desk phone has a volume control, lower until the distortion
disappears.
If the distortion is still present, adjust the headset volume control to lower
the headset speaker volume. If the distortion persists, lower the listening
volume dial on the base.
Make sure there are at least 12 inches between your base and your computer,
and 6 inches between your base and your telephone.
I hear echo in the headset. Lower the listening volume dial and speaking volume dial on the base. For
most telephones, the correct setting is position 3.
If the audio level is too low in this position, adjust the headset volume control
to increase the headset speaker volume.
If your speaking volume is too low for your listener in this position, adjust the
position of the headset to make sure the microphone is as close as possible
to your mouth.
Adjust the configuration switch. The most commonly used position is “A”,
which is the default position.
People I talk to can hear a
buzz in the background. Move the base further away from your phone.
If the base power supply is plugged into a power strip, plug it into the wall
directly.
The handset lifter is
installed, but does not lift
the handset. Ensure the handset lifter power cord is firmly pushed into the handset lifter
jack on the base.
