About the LCD Panel
The life of the LCD panel is limited.
Take care over the points below so as to use the panel for years.
• To prolong the life of this panel, never fail to turn the power off when the panel is not in use
and make sure that the lamp has gone out. The state of the lamp being extinguished helps
enhance the effect of energy saving.
• If the air filter is stained and is clogged up, the main unit inner temperature rises. As a
result, the life of the LCD is shortened and a malfunction may also occur.
Clean the air filter from time to time
61
and replace it regularly. It is recommended that
this replacement be done at the time of replacing a lamp. (Ask a dealer where the unit was
purchased or your nearby service station about an air filter for replacement.)
