Why are high-frequency sounds missing on my Optimus SCT-56?

If high-frequency sounds are missing from your Optimus Cassette Player, it could be because: * A tape recorded without Dolby NR is being played back with DOLBY NR set to B or C. Correctly set DOLBY NR. * The tape heads are dirty. Clean the tape heads.
