Troubleshooting
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 optimize the position of the headset. See Position your headset.
Headset has to be charged
too often.
Talk time is not as long as
stated.
Switch the Wideband-Narrowband audio switch to narrowband (black).
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.
I can’t subscribe a headset
to the base.
Make sure both the headset and base have the red XD markings.
See Subscription button in this user guide.
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 control 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 is 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 2.
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 is 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 2.
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.
Be sure the handset lifter power cord is firmly pushed into the handset lifter jack
on the base.
