Specific Conditions of Use (X):
1. Precautions shall be taken to minimize the risk from electrostatic
discharges and propagating brush discharges. Only clean with a
damp cloth.
2. The display glass shall be positioned in such a way as to minimize the
risk of mechanical impact.
3. When used in locations where the use of EPL Ga equipment is
required and the selected enclosure material is aluminium it shall be
installed in such a way that sparking as a result of impact or friction is
excluded.
