BTU-1000 owners manual

Thank you for purchasing the BTU-1000,
a unique combination of 4 powerful musical tools:

● Chromatic tuner:

The tuner is suitable to tune any instrument due to it’s full flexibility. The
extensive tuning range can detect all notes between A0 (27,5Hz) and
C8 (4186,0Hz). It’s accuracy of +/- 1 cent is far beyond human ear’s
distinction. Pitch of standard note A=440 can be altered from 410Hz to
480Hz and 4 different scales of guitar tuning are available: C, Bb, Eb
and F. Also, flat tuning up to two notes down can be easily set.

● Chord computer:

The chord database can be used in two modes. Mode 1 will accept a
chord name and display the chord’s finger setting on the guitar neck and
in up to 4 alternate positions. Mode 2 will allow you to mark the finger
positions on the guitar neck and give you the chord name. 2640 chords
are available!

● Metronome:

The metronome is very flexible and the ‘louder than loud’ volume plus
earphone jack will assure that even a drummer can use this to keep
pace.

● Tone generator:

All tones of the fourth octave can be generated. Standard pitch can
be adjusted from 410Hz to 480Hz. Very convenient for certain wind
instruments!
