FROM : Michael Katzmann, Chief, Materials Development Division
Subject : Digital player software upgrade
A minor issue was discovered with the digital talking-book player software version 2.1.0,
released last week and described in the Machines and Accessories bulletin 09-02. Tone
adjustment messages (e.g., tone up," tone down," etc.) were always rendered at the
normal tone setting. The book audio was correctly rendered with tone adjustment.
NLS has corrected this issue with version 2.1.1., available for download at
Since the issue is minor, it is not necessary to recall players to apply the correction.
Please use the latest version of software when updating players in the future.
