CAUTIONS ON HANDLING THE UNIT

' Dew condensation

You know such phenomenon that, in winter, a window-
pane of the heated room develops some amount of dews
on its surface. This phenomenon of dew condensation
may also occur at the object lens in the pick-up unit in
the following instances.

When the compact disc player is operated immediately
after you have turned on a heating device in your room.
When it is operated in a room full of wet air (with steam
or moisture).

- When it is operated in a warm place to which it has been
moved from a rather cold place.
If the object lens has some amount of dew condensed
on it, the compact disc player may fail to operate core
rectly as it cant read out the information data recorded
on the disc surface. If such occurs, remove the compact
disc from the disc table, turn on the power switch and
leave the unit for some time (about 1 hour at the longest);
then it will resume its normal operation.

I Proper use of the remote control

Aim (within range of 60° with no obstacles) the remote con
trol at the remote control sensor and operate as shown.

Exposing the sensor on the main unit to strong light can in»
terfere with operation. Change lighting or direction of the
unit.

Keep the remote control away from moisture, excessive
heat, shock, and vibrations.

The remote controls usable range is between 0.2 m (0.7
feet) and 6 m (20 feet) away from the sensor.

Notes concerning use:
Replace the batteries if control distance decreases or oper-
ation becomes erratic.
Periodically clean the transmitter window on the remote
control and the sensor on the main unit with a soft cloth.
