5.4 Cautionary Notes to Computer
Users
When using any headset with a
computer, take care 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.
CHAPTER 5: Troubleshooting
• 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.
Headsets in this user guide meet
all OSHA, UL, FCC and CSA
standards.
