Motor Speed Diagnostics

There is a 2 minute time period marked in the tape in order to check the cassette tape motor speed. The tape will tell you when to start timing the event. Then the tape will play about 1 minute and 50 seconds of music. Finally, the tape will tell you when to stop timing the event. If you time the event between 1 minute and 50 seconds and 2 minutes and 1 second, then the tape motor speed is within specifications.

Use the 2 minute time period on the tape in order to verify or resolve problems when a customer complains that the audio from the cassette sounds abnormal. In some cases, improper speed of the tape motor causes abnormalities in the audio.
