Cooling fans are mounted in the device. Therefore, do not put an object near the
ventilation slots. Doing this causes heat inside the device to accumulate and might
damage it. Also, do not put your head near the ventilation slots, since your hair
could be sicked into the into the device, causing injury.
Wait at least two seconds before restarting a GR4000 or GS4000 once it has been
powered off.
While the access lamp (ACC LED) for a basic control unit (BCU) is lit, the memory
card (MC) is being accessed. Do not pull out a memory card or turn off the power
switch while the memory card is being accessed. If so, you could permanently
damage the memory card.
When moving the device, do not hold the handle of a power supply unit. These
handles are not intended for this purpose and could break off, causing the power
supply unit and the device to fall, which could cause injury to you. The device itself
could also be damaged, which could cause a shock or fire hazard.
Do not install optional components from a GR4000 or GS4000 into devices other
than another GR4000 or GS4000. Doing this could cause a fire or an electric shock.
