Using cassettes
• When using a cassette for the first time we recommend
that you run the tape for about five seconds before
recording.
• When using a cassette that has been stored for a long
time we recommend that you fast-forward and rewind
it for some time. This will correct any winding
irregularity in the cassette.
• Do not repeatedly insert and remove a cassette without
running it. The tape may become slacked or damaged.
