Notes:
1. 120-minute cassette tape
Since a 120-minute cassette tape is very thin, the tape could
adhere to the pinch roller or be easily cut. It is recommended that
these tapes not be used with this unit to prevent possible
damage.

To store cassette tapes
Do not store the tapes in a place which is subject to direct sunlight,
or near equipment that generates heat. Keep the cassette tapes
away from any magnetic field.
When there is slack in the tape
In such a case, insert a pencil into the reel hole and wind the reel hub
to remove the slack.
2. Endless tapes
Do not use an endless tape, as this could damage the mechanism
of the unit.
When the recording/playback head is magnetized,
Note:
When cleaning, pay special attention so as not to
apply shock to them.
Beware of condensation
When water vapor comes into contact with the surface of cold
material, water drops are produced.
lf condensation occurs, correct operation may not be possible, or
the unit may not function correctly.
This is nota malfunction, however, and the unit should be dried. (To
do this, turn the POWER switch ON and leave the unit as it is for
several hours.)
Be especially careful in the following conditions:
@ When the unit is brought from a cold place to a warm place, and
there is a large temperature difference.
e@ When a heater starts operating.
@ When the unit is brought from an air-conditioned place to a place
of high temperature with high humidity.
@ When there is a large difference between the internal tempera-
ture of the unit and the ambient temperature, or in conditions
where condensation occurs easily.

Antenna connections
@ AM loop antenna connection
The supplied antenna is for indoor use. Place it as far as possible
from the main system, TV set, speaker cords and power cord, and
set it to a direction which provides the best reception.
Antenna stand
@ AM outdoor antenna connection
If the reception is poor when the AM loop antenna is used, distribute
a vinyl-coated wire of more than 6 meters outdoors, without
disconnecting the loop antenna.
@ FM outdoor antenna connection
It is recommended to install an exclusive FM outdoor antenna to
capture FM broadcasts with high sound quality.
Use a coaxial cable for the connection between the outdoor antenna
and FM ANTENNA terminal on the rear panel. For the connection
between the coaxial cable and FM ANTENNA terminal, please refer
to the illustration.
AM
@ FM indoor antenna connection
The supplied antenna is for indoor use. For stable reception, remove
the indoor antenna after installing an outdoor antenna as soon as
possible.

connect the speakers and speaker cords correctly.
Notes:
1. Connect all cords firmly. If connections are loose, there could be loss of sound or noise produced.
2. When plugging and unplugging connection cords be sure to first remove the power cord from the AC outlet. Plugging/unplugging connection
cords without removal of the power cord can cause malfunctions or damage to the unit.
3. Do not connect up a power source which is larger than that indicated on the socket at the rear of the unit.
