Cassette care
•Avoid touching the tape surface of a cassette to prevent
contamination of the heads by dirt, dust, or oil on the skin.
•Keep cassettes away from equipment with magnets, such
as speakers and amplifiers, as erasure or distortion on the
recorded tape could occur.
•Do not expose cassettes to direct sunlight, extremely cold
temperatures or moisture.
Note on cassettes longer than 90 minutes
We do not recommend the use of cassettes longer than 90
minutes except for long continuous playback.

Adjusting the Recording Level

The proper recording level, which differs according to the
tape type, is indicated on the peak level meters for each tape
type.
Adjust the REC LEVEL control as high as possible without
exceeding the recommended range for the inserted tape.

Tips on recording level adjustment
Setting the recording level too low will produce a hissing
sound, while setting it too high will produce distortion.
Generally, the proper recording level for high and low
frequencies is lower than that for middle frequencies. When
recording program sources with many high and low
frequencies, set the level to a relatively low position, then
make adjustments according to the recording results.
Recording FM Broadcasts With the Dolby NR
System
If your tuner does not have an MPX filter, or, if equipped,
the filter is not working effectively, set the MPX FILTER
button to ON (the FILTER indicator appears) when

recording FM broadcasts with the Dolby NR system.

The MPX filter eliminates remnants of the 19-kHz stereo
carrier and 38-kHz subcarrier signals which may impair the
operation of the Dolby NR system. Be sure to turn on the
DOLBY NR switch since the MPX filter will not function
otherwise.
