Pressing the key "E" makes the arrow disappear. The Tuning Set is now in the selected mode.
With the keys "<" and ">" you can now carry out your previously selected mode.
By pressing the key "E" again you enter the next user mode.
If the arrow will reappear, you have left the mode. With the keys "<" and ">" you may select a
new mode of operation. The input or adjustment made within a mode will remain intact after you
exit the mode.
A special case ist the mode number 6 (MEMORY). This mode you only can leave by tapping
both keys "S" and "E".
All inputs or adjustments made in the operation modes will not be erased by turning the Tuning
Set on or off. One exception is the standard pitch, which automatically resets to a1 after the
Tuning Set is turned on.
1.5 Erasing all inputs
Should you have stumbled in your first walking trials, and put in a non desired setting, you may
return to the original settings contained in the Tuning Set upon delivery:
Standard pitch:
440 Hz
Temperature: Equal Temperament
Stretching: None
Transpose Function and Cent Relate Function:

Operate as follows:
Turn off the Tuning Set. Simultaneously depress keys "A"
and "E" with the left hand until you have switched on the

1.6 Timer switch
A timer was installed in the Tuning Set, to save battery power. If you don't use the set for twenty
minutes, it will automatically turn off. Before shutdown it will set off several short accoustical
signals. This allows you to prevent shutdown by depressing one of the five keys. If the Tuning
Set automatically turned off, you may restart it with the on/off lever on the right side by switching
it off and on. You may turn off the timer completely (see chapter 3.7).
1.7 Sensivity adjustment of the built in microphone amplifier
You may reduce the sensitivity of the built-in microphone amplifier with the slide switch located
on the right side below of the Tuning Set. You may need this especially for the low tones of a
piano. The optimal setting of this switch and the optimal placement of the Tuning Set must be
found during the tuning process.
2 Operating Examples
2.1 Tuning, equal temperament, standard pitch 440 Hertz.
Normally a musical instrument is tuned in standard equal temperament. The standard concert
pitch a', on which the complete level of pitch is based, is often tuned to a frequency of 440
Hertz. This is the mode with the fewest operational steps. Therefore let us take this mode for
our first example.
