You can now record a greeting message using your PC or external
audio device.

TROUBLESHOOTING
PROBLEM
I cannot hear a dial tone when I try to make or receive a phone call.
If you are using an AC Power Supply, confirm that it is plugged
in and the power outlet is turned on.
If you are using batteries, confirm that they are new and placed
in the battery compartment correctly.
Check that the Headset/Handset Selector Switch (6) is switched
to Headset.
Check that you have lifted the telephone handset out of
the cradle.
Check that the telephone handset cable and the short curly cord
to the telephone are connected in the correct jacks.
See Fig (B).
Check that the Compatibility Slide Switch (2) is in the correct
setting for your telephone. See Fig (E). You may want to try
moving the switch through all of the positions until you hear a
clear dial tone. Experimenting with various switch settings will
not harm the adapter or your telephone.
PROBLEM
Callers say that they can’t hear me at all or they can’t hear me
very well.
Make sure the microphone of your headset is
positioned in front or near your mouth. If you are
using a noise-cancelling headset, the position of
the microphone is very important.
You may need to adjust the Speak Volume Control (4).
See Fig (G).
Check that the Compatibility Slide Switch (2) is in the correct
setting for your telephone. See Fig (E). You may want to try
moving the switch through all of the positions until your caller
hears you clearly. Experimenting with various switch settings will
not harm the adapter or your telephone.

PROBLEM
I hear a low pitch hum in my headset speaker and/or my callers complain
they can hear a hum.
Move the Compatibility Slide Switch (2) between position 5
and 6 to see if the hum disappears in either position.
Ensure the External Audio Device Cable is routed away from
your monitor or other electrical device.
PROBLEM
I hear three ‘beeps’ in the headset.
If you are using batteries to power the MX10 Multimedia
Adapter, the three ‘beeps’ are telling you that the
batteries are low and need to be replaced. Refer to
the Installation section.
PROBLEM
The microphone level to my computer is too loud.
Check that the green jack plug on the external audio
device cord is plugged into the "Mic In" jack on the
soundcard.
Review your soundcard "Mixer" settings on the computer
to adjust the microphone volume.
PROBLEM
The sound from my computer is distorted.
Plug the black jack plug on the external audio device cord
into the "Line Out" jack and adjust the External Audio Listen
Volume Control (10) for comfortable volume.
PROBLEM
I am using my Headset Switcher Adapter with an audio device and no
telephone. I cannot hear the audio device.
Move the Compatibility Slide Switch (2) to position 5. Depress
the Telephone/Computer Audio Switch (7) (coloured indicator
showing). Depress the Microphone Selection Switch (8)
(coloured indicator showing).
