The optimum recording level, which differs according to the
tape type, is indicated on the PEAK LEVEL METER for each
tape type.
Adjust the REC LEVEL control as high as possible without
exceeding the recommended range for the tape type being
used.

Tips on recording level adjustment
+ If the recording level setting is too high, the recording will
be distorted; if it is too low, the tape will produce a hissing
sound. Therefore, the recording level should be set as high
as possible without causing distortion.
+ If the program source to be recorded has many high
frequency signals, set the level to a relatively low position.

Tape Type—Bias Adjustment
To obtain the optimum frequency response, use the BIAS
control to adjust the bias current according to the tape type
being used. Reducing the bias boosts high frequencies but
increases distortion. Increasing the bias decreases distortion
but suppresses high frequencies. Balance the bias according
to your listening preference.

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
The use of cassettes longer than 90 minutes is not
recommended except for long continuous playback.
