handle firmly, so that it cannot drop accidentally and cause injury. Comply with
the instructions written on the caution label attached on the device.
Do not install the device in a dusty or humid location. Doing so may cause a fire
or an electric shock.
Condensation may form on the surface and inside of the device if it is moved from
a cold to a warm location. Using the device in this condition may cause a fire or
an electric shock. After moving the device between two locations with a large
temperature variation, let the device stand for a few hours before using.
Do not put your hands into the device when it is operating, since you could be
injured by a moving part.
Do not put the power cable near a heater, since it could melt the power cable
casing a fire or an electric shock.
Always hold the power plug when inserting or removing the power cable into or
from the outlet. Pulling on the cable can cause the wires to break.
Be careful with optical
network interfaces. The
board with the label (shown
at the right) shows that a
laser is used. Never directly
look into the optical ports.
The GR4000 or GS4000
contains a lithium battery for
the real-time clock.
Mishandling this battery
may cause overheating,
damage, or in an extreme
case, explosion or fire. Do
not remove the battery,
attempt to disassemble it, or
expose it to temperatures of over 100°C (212°F). Also, do not incinerate or
dispose of this battery in water.
Remove dust on or around the device regularly. Accumulated dust can choke off
ventilation to components, causes fans to fail, and could cause a fire or an
electric shock.
Once the device is powered up, an inrush of electrical current occurs. Do not
operate this device during a reduced voltage condition (brownout). Similarly, do
not allow the voltage of a power facility under your control to decrease. A
