11. Moisture Condensation
Moisture condensation may damage this unit. Read the following carefully:
When you take a glass containing a cold drink outside on a summer’s day, drops of water, called condensation, form on the outside of the glass. Similarly, moisture may condense on the lens of the optical pickup, one of the most important parts inside this unit.
•Moisture condensation can occur in the following sit- uations:
—The unit is moved from a cold place to a warm place.
—A heater is turned on, or cold air from an air condi- tioner is hitting the unit.
—In the summer, when this unit is moved from an air conditioned room to a hot and humid place.
—The unit is used in a humid place.
•Do not use this unit when there’s the possibility of moisture condensation occurring. Doing so may dam- age your discs and certain parts inside this unit.
If condensation does occur, remove all discs and leave this unit turned on for two to three hours. By this time, the unit will have warmed up and any condensation will have evaporated. To reduce the risk of condensa- tion, keep this unit connected to a wall outlet.
