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.
