SPEAKER AUDIO
The TDAP-611 has a speaker channel that may be used as a “music only” feed for a passenger
cabin area, if desired. This is an optional connection and does not have to be used. The speaker
level is driven by the front panel MUSIC control and by an optionally attached external music
volume control.

CHANGING RADIO LEGENDS
The legends on the TDAP-611 front panel pushbuttons can all be easily changed in the field to
suit special requirements. The legend insert is adhesive and can be removed by lifting a corner
free with a sharp X-acto knife blade and then gently pulling the entire Lexan strip free. Remove
the backing from a new legend strip (with the desired legends), line it up evenly, and press it into
place on the overlay recess. The adhesive will cure fully in 48 hours. Be sure any bubbles are
pressed out, and that all edges are firmly attached with no exposed lighted edges.
