This product contains a lithium battery.
Do not use a metal or other conductive implement to remove the battery. If a short-circuit is
made between its positive and negative terminals the battery may explode.
Replace a discharged battery with one of the same type; another type may explode or ignite.
Follow the instructions contained in section 3 of this document to replace the battery. Dispose of
a discharged battery promptly and in accordance with the battery manufacturer’s recommended
instructions. Do not recharge, disassemble or incinerate the discharged battery. Keep discharged
batteries away from children.

Warning
Static electricity can cause permanent damage to electronic components. You should be
aware of this risk, and take precautions against the discharge of static electricity.
This product is at risk from static discharge because the electronic components of the
motherboard are exposed. Memory modules and replacement processors are examples of
electrostatic sensitive devices (ESSDs).
All work that involves contact with the TN810 ATX Motherboard should be done in an area
completely free of static electricity. We recommend using a Special Handling Area (SHA) as
defined by EN 100015-1: 1992. This means that working surfaces, floor coverings and chairs
must be connected to a common earth reference point, and you should wear an earthed wrist
strap and anti-static clothing. It is also a good idea to use an ionizer or humidifier to remove
static from the air.
Handle static-sensitive items with extreme care. Hold add-on components only by their edges,
avoiding their electrical contacts. In general, do not handle static-sensitive items unnecessarily.
Keep all conductive material, and food and drink, away from your work area and the TN810
ATX Motherboard.
