GS4000 Quick Start Guide, Revision 3
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 sucked 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. Some
commands can take a while to finish access to a memory card. Always make sure that access
to a memory card is completely finished before pulling out a memory card or turning off the
power switch.
