About the LCD display on the
display section
When the temperature is extremely high
or low, the display may become dim and
hard to see. This is due to the
characteristics of the LCD and is not a
malfunction. The display will return to
normal when the temperature becomes
normal.
Wireless remote
Installing batteries in the wireless
remote
Insert two size-AA (R6) batteries with
the correct polarity.
Battery life
When the batteries become weak, you
will not be able to operate the unit with
the wireless remote. Battery life is about
six months (or shorter, depending on the
way the remote is used). If the remote
becomes inoperative, replace the
batteries, then verify that it can operate
the system.
O
PEN
Do not expose the discs to direct
sunlight or heat sources such as hot air-
ducts, or leave them in a car parked in
direct sunlight where there can be a
considerable rise in the temperature
inside the car.
Before playing, clean the discs with an
optional cleaning cloth. Wipe each disc
from the centre out.
Do not use solvents such as benzine,
thinner, commercially available cleaners
or antistatic spray intended for analog
discs.
Note on moisture condensation
On a rainy day or in a very damp area,
moisture may condense on the lenses
inside the CD player. Should this occur,
the unit will not operate properly. In this
case, remove the disc and wait for about
an hour until the moisture evaporates.
When you play 8 cm CDs
Use the optional Sony compact disc
single adapter (CSA-8) to protect the CD
player from being damaged.
