How the Nº31
"remembers" programs

Programming
Rather than playing an entire CD, you may choose to play only
certain selections. To do this, you create a "program" and store it in the
Nº31's memory.
Before using your Nº31's programming features, become familiar with
its controls and their locations (see "Front panel," "Top panel," "CD
transport assembly," and "Remote Control"), as well as their basic
functions (see "Basic operation").
Note: The Nº31's basic functions operate as described in "Basic
operation," except that they affect only the program, not the
entire CD.
For instance, pressing Next during play skips to the next track or
index in the sequence, whether or not it's the next track or index
on the CD.
In the same way, pressing repeat disc will repeat the entire
program, not the entire CD.
The Nº31 allows up to 99 selections (tracks and indexes) per program.
A program may include both tracks and indexes.
Assembling a program is possible only before play begins.
Note: The only programming functions that operate while a CD
is playing are program clear and program save.
When you load a CD, the Nº31 assigns it a unique identification code.
If you assemble a program for a particular CD and save it into the
Nº31's memory, the Nº31 "remembers" that CD's program.
The next time you load that CD, the Nº31 will recognize the CD's
identification code and automatically loads the previously saved
program. (The letter P will appear preceding the track number on the
Display.)
Note: Even if you'd previously saved a program for a CD, the
Nº31 allows you to override it (and have access to all tracks on
the CD) without erasing it from the memory.
To override a previously saved program, press program clear; or
on the Remote Control, press the 0 (zero) numbered key, then
press prg/time. All of the CD's tracks will be accessible for basic
operation, but the program will still be retained in the Nº31's
memory. (See "Basic operation.")
The Nº31's memory can store programs for up to 1,300 different CDs.
Saved programs remain in memory when you place the Nº31 into
standby, when you turn off the main power switch — even if AC power
is interrupted.
