* CAUTION
To prevent its panels and circuits, overheating when the surrounding temperature exceeds 40°C, this unit raises
the rotational speed of the fan automatically to cool the insides. (The fan rotation sound will become louder.)
The starting temperature of the above protection operation differs according to the images displayed, ventilation
conditions of the external environment, whether dust has accumulated in the vents of the Plasma Display, etc.
Use the Plasma Display in surrounding temperatures below 40°C.
CAUTION
To protect the panel drive circuit against unstable signal inputs, operations such as switching of inputs cannot
be performed until the input becomes stable again.
Consequently, if an equipment connected to the unit outputs unstable signals, it may not be possible to per-
form operations using the remote controller and buttons on the unit. This can be solved by disconnecting the
equipment outputting the unstable signal.
