The memory content for Temperatures and Stretchings will not be erased by the 'dump'.
....and this is how to do it:
Turn off the Tuning Set. Simultaneously depress keys "A" and "E" with the left hand until you have
switched on the Tuning Set with your right hand.
Continue holding the keys until the LC-Display indicates:

IS DONE
The 'monkey clutch' was made so difficult to prevent an accidental dumping of the inputs and
settings.
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 SENSITIVITY 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 left side 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.

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.
Switch on CTS-5.
Display: >1< TUNING >
Tap key "E" briefly.
Display: a 1 PITCH: 440.0
>1< CENTS: 00.0
Now strike the tone a' on your instrument. Two green illuminated sets of beads appear on the
stroboscopic display. The beads move to the left if the tone is too low, or to the right if the tone is
