Moisture condensation

In the following cases, condensation may form inside

the unit.

Shortly after turning on a heater.

When the unit is placed in a room where there is ex-

cessive steam or moisture.

When the unit is moved from a cool place to a warm

place.

When the unit has condensation inside, the disc signals

cannot be read, and the product may not function

properly.

If this happens, remove the disc, and open the disc

holder. The condensation should evaporate in approxi-

mately 1 hour. The unit will then function properly.

If a problem occurs

If this product is subjected to strong external inter-

ference (mechanical shock, excessive static electricity,

abnormal supply voltage due to lightning, etc.) or if it

is operated incorrectly, it may malfunction or the display

may not function correctly. If such a problem occurs,

do the following:

Unplug the AC power lead from the AC socket.

Wait about 20 - 30 seconds and then plug the AC power

lead back into the AC socket.

Press the reset button on the back of the unit.

When the reset button is pressed, all of the settings in

memory will be erased.

If strange sounds, smells or smoke come out of the unit

or if a foreign object falls into the unit, turn off the power,

unplug the AC power lead from the AC socket, immedi-

ately. Contact the shop where you purchased the unit.

If a power failure occurs during recording

If the AC power plug is disconnected from the AC socket

or a power failure occurs during recording (before the

TOC information has been recorded on the disc), the

audio portion being recorded at that time will be erased.

When a recording is being added to a MiniDisc which

already has a recording on it, if the TOC is not updated

before the power failure, the added recording will be

erased.

If a power failure occurs or the AC power lead is dis-

connected for about 10 minutes, when power is restored,

the TOC will be written on the disc.

RESET

Pen, pencil, etc.

REMOTE CONTROL

Proper use of the remote control

Aim the remote control at the remote control sensor within 30

o

with no obstacles, and operate as shown.

Notes concerning use:

Replace the batteries if the control distance decreases or

operation becomes erratic.

Periodically clean the transmitter window on the remote

control and the sensor on the main unit with a soft cloth.

Exposing the sensor on the main unit to strong light can

interfere with operation. Change the lighting or the direction

of the unit.
