Cautionary Notes to

Computer Users

When using any headset with a computer, care should be taken in dry or low-humidity environments to protect the user from electrostatic discharge from the monitor (CRT). Computer monitors can induce a substantial electrostatic charge when turned on or off, or when there is a power failure, and the resulting electrostatic discharge can be passed through the headset to ground.

A user in close proximity to or touching the computer may feel a common “shock” sensation, similar to touching a doorknob after walking across a carpet, causing no harm to the user. This discharge is entirely due to the computer monitor; the headset is merely the shortest path to ground.

To minimize the possibility of electrostatic discharge through the headset, you can:

•Use a grounded screen in front of the monitor.

•Use static-dissipative wrist straps.

•Increase the relative humidity in the room to 60% or more.

•Install static-dissipative carpets or floor coverings (anti-static sprays can be helpful).

•Remove the headset before turning the computer on or off.

The 2-in-1 Headsets meet all OSHA, UL, FCC and CSA standards.
