Precautions
1. If it should appear to be malfunctioning, discontinue
use immediately and have it inspected by qualified
service personnel.
2. Please use the specified adaptor only. Using the wrong
adaptor can result in damage to the instrument or
overheating.
3. Unplug the AC power adaptor when not using the
instrument, or during electrical storms. Please unplug
the power by removing the adaptor, but not dragging
the wire directly.
4. Do not expose the instrument to excessive dust or
vibrations, or extreme cold or heat environment to
prevent the possibility of panel disfigurements or
damage to the internal components.
5. Before cleaning the instrument, always remove the
electric plug form the outlet. Never insert or remove
an electric plug with wet hands. Check the electric plug
periodically and remove any dirt or dust which may
have accumulated on it.
6. When cleaning the instrument, use a soft, dry cloth.
Do not use paint thinner, solvents, cleaning fluids,
or chemical-impregnated wiping cloths. Also, do not
place vinyl, plastic or rubber objects on the instrument,
since this might discolor the panel or keyboard.
