Controls from their default settings. If you have an issue with sound
quality and you cannot resolve it using the volume controls on the NBX
Telephones, contact your technical support representative.
CAUTION: Do not change your Audio Controls settings unless you are
instructed to do so by a qualified 3Com Technical Support representative.
