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.
GN Netcom, Inc. headsets meet all OSHA, UL, FCC and CS standards.
Safety Instructions
• Never try to dismantle the product yourself. None of the internal components can be
repaired by users.
• Do not expose the headset to rain or other liquids.
• The headset is equipped with a rechargeable NiMH battery (nickel-metal-hydride). For
battery replacement, please contact your distributor or reseller.
