Intermittent buzzing or humming can be caused by electrical equipment located in the immediate area of the telephone and headset system, such as fluorescent lighting, computers, fax machines, typewriters, and power strips (surge protectors). Frequently, power cords and cables that are bundled together will cause buzzing. The best solution is to keep this type of equipment separated from the headset, amplifier and telephone.
