Precautions
Some components of ROCKY-4782E2V are very sensitive to static electric charges
and can be damaged by a sudden rush of power. To protect it from unintended
damage, be sure to note these precautions:
Ground yourself to remove any static charge before touching the
ROCKY-4782E2V SBC. You can do it by using a grounded wrist strap at all times
or by frequently touching any conducting materials that is connected to the
ground.
Handle your ROCKY-4782E2V SBC by its edges. Do not touch its IC chips,
leads or circuitry unless necessary.
Do not plug any connectors or set any jumpers while the power is on.

Clear CMOS Setup (JP2)
If you have to clear the CMOS Setup (for example, if you forget your BIOS password,
you should clear the CMOS and then set the password again.), you should short JP2
(Pin2 and Pin3) for about 3 seconds, then open it again. Setting the jumper on JP2
back onto pins 1-2 will set the system for normal operation.
