Safety Precautions
Before getting started, read the following important cautions.
1. Be sure to ground yourself to prevent static charge when installing the internal
components. Use a grounding wrist strap and place all electronic components in any
static-shielded devices. Most electronic components are sensitive to static electrical
charge.
2. Disconnect the power cords from the GOT712S Series before making any installation. Be
sure both the system and the external devices are turned OFF. Sudden surge of power
could ruin sensitive components. Make sure the GOT712S Series is properly grounded.
3. Do not open the system’s top cover. If opening the cover for maintenance is a must, only
a trained technician is allowed to do so. Integrated circuits on computer boards are
sensitive to static electricity. To avoid damaging chips from electrostatic discharge,
observe the following precautions:
◼Before handling a board or integrated circuit, touch an unpainted portion of the
system unit chassis for a few seconds. This will help to discharge any static electricity
on your body.
◼When handling boards and components, wear a wrist-grounding strap, available
from most electronic component stores.
