I can't hear a dial tone in the
headset. Adjust the configuration on the switcher until a dial tone is heard.
If the volume is too low, adjust the listening volume dial on the
bottom of the switcher.
Make sure the lifter is lifting the handset high enough too operate
the hookswitch; set to a higher setting if necessary.
The sound is distorted. Lower the speaking volume dial and/or listening volume dial on the
switcher. For most telephone the correct setting is position 2.
If your desk phone has a volume control, lower until the distortion
disappears,
I hear echo in the headset. Lower the listening volume and the speaking volume dials on the
switcher. For most telephone, the correct setting is position 2.
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. If the power supply (HL10 lifter only) 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 optional AC power adapter is firmly pushed into the
handset power jack on the switcher.
When I dial from my softphone
application, nothing happens. Ensure that the MDA500 is the default sound device. The control
panel will launch the sound devices control panel by going to
Control Panels > Sound
Ensure that you are using a compatible softphone application. For
a list of compatible softphones, visit plantronics.com/software.
If the Hub software in not installed and you do not have a
compatible softphone, you must first press the headset call button
and then use the softphone interface to place/answer/end calls.
Restart your computer

The sound is distorted or I hear an
