Accessories for the M3900 Series telephones
Headsets
Amplified and unamplified
Headsets
are compatible with your M3900 Series
Meridian Digital Telephone. The amplified headset is an option for noisy
environments.
Headsets vary in electrical, physical and audio characteristics. Performance
perception is subjective so it is recommended that the headset user try using their
headset with each of the three settings on both internal and external calls to
determine which works best for them.
To adjust the headset volume, go to the Options menu, Headset types and select
one of the headset types from the sub-menu item: Headset 1, Headset 2 or
Amplified.
Refer to your distributor for the latest product bulletin from Nortel Networks for
recommended headset types for the M3900 Series telephone.
