Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Playback speed on that model may be controlled to anywhere from 50 % of original speed, to 200 % of the original speed.
During playback, press the OK button and then the << or the >> button to change the playback speed.
But [Noise Cancel] has to not be enabled, for this to be possible!
Also stereo playback will turn to Mono mode playback, while S. Play or F. Play is going on.
Please rate my answer, since this does answer your question beyond any doubt, I think. Thanks!
