1 Initial Operations
1.1 Power supply
The Tuning Set is equipped with 4 rechargeable NiMH batteries (1.2 Volt 2000 mAh). The operat-
ing period with one battery charge lasts approx. 12 hours. When the batteries are low, the indica-
tor "LOW BAT" appears in the LC-display. In order to avoid deep discharge of the batteries, the
device will automatically shut off. The battery can be recharged with the supplied plug-in trans-
former. The batteries are fully recharged after approx. 14 hours. When the plug-in transformer is
connected, the yellow charge control LED is lit. When the batteries are fully charged, the trans-
former will not automatically shut down. Therefore, the tuning device should be disconnected after
the charge. The instrument can be operated without risk during the recharging process.
Should the operating period with one battery charge decrease at some point to much less than
8 hours, the following may have occurred:
1. The battery set is defect. Measure to be taken: Install new batteries.
2. The plug-in transformer is defect. Measure to be taken: Replace the transformer.
(7.5 Volt (min) 360 mA DC stabilized, hollow plug 5 x 2 mm plus outside)
3. The Tuning Set is defect. Measure to be taken: The charger and Tuning Set should be sent in
for maintenance.
If you constantly use the device with the plug-in transformer connected, it is advisable to remove
the batteries to avoid permanent-charging damage.
1.2 Battery change
Remove back cover.
Replace batteries and pay attention to the
correct polarity.
Please use only rechargeable NiMh batte-
ries. Non-Rechargeable Batteries are leaking
when the AC adapter is plugged in. The acid
will destroy the device.

1.3 Setting up the device
1.4 Recording
Recording takes place by means of a built-in condenser microphone. An external microphone
jack (3.5 mm) can be plugged into the socket, also found on the right-hand side of the device.
This deactivates the internal microphone.
You can adjust the sensitivity of the built-in microphone with the slide switch (high/low) located on
the right 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.
1.5 Active box for audible tone (CTS-7-CE only)
You can raise the volume of the audible tone by plugging an active box with a 3.5 mm jack (avail-
able at computer shops) into the socket located on the backside of the set.
1.6 Switching on the Tuning Set
Turn on the Tuning Set with the slide switch on its right-hand side. For approximately one second
you see the program version, and then the following indication appears:
1.7 Resetting the device to factory settings
Selecting the wrong key or mode will not damage the Tuning Set. The permanently stored tempe-
raments and stretchings cannot be erased or changed by pressing a wrong key (exception see
chapter 1.8). In order to become acquainted with the Tuning Set, you may play and experiment
with the keys as much as you wish. Should you have stumbled in your first "walking trials” and
programmed a non-desired setting, you can always return to the original settings and reset the
Tuning Set as follows:

3. Keep the keys pressed until this display is indicated.
4. Let go of the keys.
5. Select your language with the “Func“ keys and confirm
with the “E“ key.
6. After ca.10 seconds this display will be indicated.
Resetting CTS-7 was successful and the set is now in
the tuning mode.
1.8 Deleting all memories
!!! Attention: all your data will be lost !!!
Clear all memories and reset the device to delivery status:
1. Switch off the device.
2. While pressing the keys “F“ and “E“ simultaneously, switch on the device.
3. Immediately after that tap „S“ key four times in quick succession.
4. Select your language with the “Func“ keys and confirm with the “E“ key.
2 Tuning Mode (Basic Tuning Functions)
The basic tuning functions are summarized in the “Quick Reference Guide for the Tuning Mode“.
To become well familiar with the Tuning Set, follow the operating examples below on a musical
instrument and stick closely to the instructions.
2.1 Strobe display
Strike the tone a1 on your instrument. Two fields of green
light will appear in the strobe display.
When the played tone is too low or too high, these fields move to the left or right accordingly.
When the tone comes closer to its target value, the movement becomes slower.
Once the tone is correct, the fields stop moving.
You can recognize large frequency deviations, when
one of the two green dots on the left or right of the
strobe display is lit. Depending on whether the tone
being tuned is too high or too low, either the right or the
left dot will be lit continuously. If neither of these two
dots shine, the tone played is at the desired pitch of +/-
4 cent. If a strobe field moves across the display once
in 20 seconds, the frequency deviation is 0,1 Hertz.
2.2 Bar graph display
In the tuning mode, you can switch between the bar graph and the concert pitch display with the
“E” key.
Press the “E“ key. When you now strike the tone a1 on your
instrument, the arrow points to the right, if the tone played
is too high, and to the left, if it is too low.

2.4.1 Automatic tone adjustment mode
When both “Note” keys are pressed simultaneously, switching to
another tone occurs automatically from this point on. The device
automatically follows the tone level of the played tone.
The activated automatic tone adjustment mode is indicated by the
rectangle shown by the arrow.
Tip: The automated switching was intentionally limited to 12
semitone steps around the played tune, to avoid tuning in the wrong
octave.
Pressing both “Note“ keys simultaneously will deactivate the auto mode again.
2.5 Selecting functions
By using the two “Func“ keys, you can change the following values:
1. Concert pitch
2. Cent
3. Partial
4. Interval
Using the “F“ key, you can select the “Func“ key’s assignment to one of the above
functions.
After switching on the Tuning Set:
The left-pointing arrow is now to the right of the pitch indicator. By
tapping one of the “Func“ keys you can change the concert pitch.
Now press the “F“ key. From this point on, the “Func“ keys are
used for cent adjustment. The left-pointing arrow is now to the
right of the cent indicator.
Now press the “F“ key again. From this point on, the “Func“
keys are used for partial tone adjustment. The left-pointing
arrow is now to the right of the partial indicator.
Now press the “F“ key again. From this point on, the “Func“
keys are used for interval adjustment. The left-pointing arrow is
now to the right of the interval indicator.
Pressing the ”F“ key again returns the “Func“ keys to the
concert pitch adjustment again.
2.6 Pitch setting (concert pitch)
The concert pitch is the principal reference tone on which the entire tonal system of the tuning
device is based. It is linked to the note a1 (a’) and is adjustable from 220 to 880 Hz in steps of
0.01Hz.

By tapping the "Func >" key, you can raise the standard pitch by
1/100th Hertz.
By tapping the "< Func" key, you can lower the standard pitch by
1/100th Hertz.
If you continually press the “S” key and simultaneously tap the
"Func>" key, you will raise the standard pitch by 0.1 Hz.
If you continually press the “S” key and simultaneously tap the
"<Func" key, you will lower the standard pitch by 0.1 Hz.
2.6.1 Automatic pitch search
If both “< Func“ and “Func >“ keys are pressed simultaneously, the
concert pitch of theTuning Set begins to move automatically
to the pitch being played at that moment (auto pitch mode).
When the pitch is found, the auto pitch mode will be deactivated
and the left-pointing arrow is indicated again.
This mode is indicated by the rectangle on the right side of the
cent display.
Watch the strobe. If it is still moving, adjust the Tuning Set to the
correct tone, by tapping the keys "< func" or "func >" repeatedly, until
the stroboscopic display stands still while the tone is being played.
Only then, the set is adjusted to the desired and highly precise value.
2.7 Cent adjustment
The cent calibration is adjustable by ±99.9 cents in steps of 0.1 cent. The unit of measure
“cent” is used in accoustics for the deviation of a tone from a basic frequency. A cent is
about one hundredth of a semitone step. The mathematical definition is described in
chapter 5.2.
Select the function “cent adjustment” with the “F” key as described in
chapter 2.5.
By tapping the „Func >” key, you can raise the cent calibration by
0.1 cent.
By tapping the „< Func” key, you can lower the cent calibration by
0.1 cent.
If you press the “S” key and simultaneously tap the
"Func >" key, you will raise the cent calibration by one cent.
By pressing the “S” key and simultaneously tapping
the "< Func" key, you will lower the cent calibration by one cent.

2.7.1 Automatic cent search
If both keys “< Func“ and “Func >“ are pressed simultaneously, and
you are playing the tone a_1, the cent calibration of the Tuning Set
begins to move automatically to the tone played on your instrument at
the moment (auto cent search mode).
This mode is indicated by the rectangle on the right-hand side of
the cent indicator.
When the correct cent value is found, the auto search mode is
deactivated and the left-pointing arrow is indicated again.
Watch the strobe. If it is still moving, adjust the Tuning Set to the correct tone, by tapping
the keys "< func" or "func >", until the strobe display stands still while the tone is being
played. Only then, the set is adjusted to the correct value.
2.8 Partial tone adjustment
Normally, a tone is composed of several partials, also called harmonics. The fundamental
(1. partial) defines the base pitch. The second partial is one octave above the fundamental,
the third partial relates with a 1:3 ratio to the fundamental, the fourth 1:4 etc.
Normally, measurements occur based on the fundamental (1. partial). For particularly low
notes or tones with a weak fundamental wave, it may be useful to do the tuning with a
higher partial for a better indication.
For partial tone adjustment, find the function selection for
partials with the “F” key as described in chapter 2.5.
Using the “Func“ keys, you can adjust partials 1 thru 8.
2.9 Pure interval tuning
For organ builders, the device includes a feature for the tuning of pure intervals.
For interval adjustment, find the function selection for partials with
the “F” key, as described in chapter 2.5.
With the “Func“ keys you can enter the following adjustments:
SEK: Second 8:9
TER: Third 4:5
QUI: Fifth 2:3
SEP: Seventh 4:7
3 Menu Control
With the different keys, you can find your way through the included “Menu Control Overview”,
like on a 'road map'. Don't try to memorize the key sequences in the examples. Simply try to
understand the operation scheme of the Tuning Set by following the examples in the overview.
In order to be able to follow the next examples, the display should
indicate the following:
If this is not the case, reset the device as described in capter 1.7.

With the “Note >“ key, you can move to the right in the menu.
With the <Note“ key, you can move back to the left.
Now, press the “Func>“ key. With this, you can select, for
example, an instrument program which contains a piano tuning.
(Detailed description how to tune pianos is in chapter 3.5.)
For example, if you intend to tune a harpsichord, you tap the
“Func >“ key several times, until this indicator appears:
Now press “E“.
Using the ”Func“ keys, you now can select one of 99 different
historical temperaments.
Tap the “Func >“ key several times, until this indicator appears:
Remark: The last two digits of the menu mark contain the memory
number of the temperament.
Press “E“. Using the “Func“ keys, you now can select the cent-
reference tone for the temperament (cent reference see chapter 5.5).
Press “E“ again. Using the “Func“ keys you now transpose the
temperament into another key (transposer see chapter 5.6)
Press “E“ again. The set is operating in the tuning mode.
Press ”Note >“ in order to raise the tone adjustment by one semitone
step. The cent adjustment for the tone “b” now corresponds to that of
the temperament “KIRNBERER-II“. This way, the cents for every tone
of the historical temperament will be indicated.
Now, press “S+E“. The Tuning Set will leave the tuning mode
and return back to the highest menu control level.
3.1 Tuning Set switch-off
You may simply turn off the device with the slide switch on the left side while in any of the
applications. Applications in which cents are being stored, should be left by pressing “S+E“ before
turning the device off, in order to store the last adjustments.
If the instrument program 1 (Normal Tuning) was active before switch-off, the device enters into
tuning mode immediately after being turned back on (overview: arrow 1). In all other cases, the
device will be at the highest menu control level after being turned back on (overview: arrow 2).

3.2 Illumination on/off
Find this indicator on the display as described in chapter 0:
Now, using the “Func“ keys, you can turn the illumination on or off.
3.3 Automatic timer
Find this indicator on the display as descibed in chapter 0:
The timer function can be turned on or off with the “Func“ keys.
A timer was installed in the Tuning Set, to save battery power.
If you don't use the set for fifteen minutes, it automatically turns
itself off.
Before shut-down, it will set off short accoustic signals for about 30 seconds. This allows you to
prevent shut-down by pressing any of the seven keys. If the Tuning Set automatically shuts down,
you can restart it with the on/off switch on the right side by switching it off and then on again.
3.4 Thermosensor calibration (CTS-7-CE only)
This menu serves to calibrate the thermosensor input for a thermosensor available as accessory
for the CTS-7-CE. The menu point is available only when a sensor is actually connected to the
device.
The thermosensor controls the target frequency of the set in
relation to the measured room temperature.
See chapters 3.9., 5.4 and 5.9.
For calibration, find this display indicator as described in chapter 0:
On the right side you see the room temperature measured by the sensor.
On the left there is an offset value that is added to the indicated temperature.
The offset can now be adjusted until the indicated temperature corresponds to the actual room
temperature. When leaving this function, the calibration offset value is stored.
3.5 Tuning pianos
First things first: One cannot overemphasize the fact that piano tuning requires experience. If it is
done without the necessary knowledge and skills, the piano may be irreparably damaged. In one
tuning, a piano should never be raised or lowered by more than 30 cent.
When tuning instruments with thick strings such as pianos and grand pianos, “stretching” the tun-
ing becomes necessary. This implies that, different from the standard tuning mode, the high tones
must be tuned higher and the low tones lower. We will discuss this further in chapter 5.7 of this
Manual.
The permanently stored instrument programs “PIANO_STRETCH_1 to 3” are considering this by
using inharmonicity curves. That is, a cent value is given for each tone, which shows the offset of
the piano tuning from the equally tempered tuning.
For these tone-stretching tasks, each of the 60 instrument programs possesses a memory space
for each tone capable of registering a deviation of up to ±99,9 cent per tone.
The selection of the optimal stretching depends on various parameters of the instrument to be
tuned. Individual preferences of the musician also play a vital role. Three permanently-stored in-
strument programs are available in the CTS-7. You may store the temperaments of up to 51 pi-
anos in the CTS-7. Using the „PIANYZER“ you can create special stretchings suitable to individu-
al instruments (see section 3.10).
The three built-in stretchings found in the system are the result of trials, during which various pi-
anos were tuned by ear, and subsequently measured. You must try out the stretching most suited
to match your particular requirements first. For your first attempts, we recommend that you try the
Piano Stretch 3. For this please apply the following:
