Tuning procedure

■
Meter mode
In this mode the VU style meter shown in the display is used to
tune your instrument.
1. If an instrument equipped with a pickup or the optional Korg
CM-200 contact microphone is used, connect the instrument or
mic cord (plug) to the INPUT jack of the CA-2.
If you wish to tune your instrument using the built-in mic, do
not connect a plug to the INPUT jack. In steps 4 and 5, place your
instrument as close as possible to the built-in mic.
If a plug is connected to the INPUT jack, the built-in mic cannot
be used. The INPUT jack is for mono use only. Stereo plugs
cannot be used.
2. Press the power button to turn on the CA-2.
When the CA-2 is turned on, the previously specified reference
pitch is indicated.
When the power is on for 20 minutes without use, the tuner will
automatically turn off to conserve battery life.
3. If you wish to change the reference pitch (calibration), press the
CALIB button. This can be adjusted in 1 Hz steps over a
or
range of 410 Hz-480 Hz.(*)
4. Play a single note on your instrument, and the name of the nearest
note will appear in the display. Tune your instrument so that the
correct note name is shown in the display.
5. Tune your instrument so that the VU style meter moves to the
position (center) and the center pitch guide LED is lit.

The left indicator of the tuning guide will light if your instrument
is flat, and the right indicator will light if your instrument is sharp.
If you want to tune a pure major third above or a pure minor third
above a certain note, make the meter indicate " " (-13.7 cents) or
" " (+15.6 cents).
For example if you want to tune a major third above the A (0 cents)
note, set the note name display to C#, and make the meter indicate
" ".
Or if you want to tune a minor third above A (0cent), set the note
name display to C, and make the meter indicate " ".
While tuning with the built-in mic a quiet environment is
recommended for precise tuning.
Even if the pitch is within the range of detection, it may not
be possible to detect the pitch of an instrumental sound that
contains large numbers of overtones or a sound that has a rapid
decay.
