QUICK RESET OF CENTS WINDOW TO ZERO

It is often convenient to be able to reset the cents reading to zero without having to go to the trouble of counting the cents

down to zero.  This can be done with the CAL button.  Hold the SHIFT button down, and press the CAL button quickly.

The CENTS window will revert to zero cents, but the  NOTE window will remain as it was and the SAT will not go over to

the CAL function.  If you want to complete the CAL operation, hold the CAL button down instead of just giving it a quick

push.

PAGE NUMBER DISPLAY

In the memory mode the CENTS display doubles as the PAGE number display.  It displays the current PAGE number or

the current CENTS setting as required.  To see how this works, hold SHIFT down and press PAGE up once.  A numeral 1

will appear in the CENTS display, to indicate that storing or retrieving a piano can now be done on or from PAGE 1.  To

change the PAGE, hold the SHIFT button down and press PAGE up or down.

NOTE:  The PAGE number will step up only to the maximum number of pages installed in your particular SAT.

Stepping down, the page numbers will eventually get you to PAGE 0.  PAGE 0 will not store any information and is there

to make it difficult to accidentally overwrite a valuable tuning.  When the SAT is turned on, the PAGE number defaults to

0.  You have to select a page before you can store a tuning to memory.

STORING AN AURAL TUNING IN MEMORY

Assuming the piano is tuned and you are storing notes from AO to C8:

1.  Turn the Accu-Tuner on and press the TUNE button.

2.  Select the PAGE by holding SHIFT and then using PAGE to get to the desired page in memory that you want to devote

to this piano.  Press NOTE up and then NOTE down to start on AO.

3.  To set the partial, press the TUNE button.  Set the display for the NOTE and OCTAVE of the desired partial, such as

E3 (sixth partial) or A2 (fourth partial) to record the note A0 on the piano.

4.  Now measure the pitch of the note on the piano by playing the note on the piano and using MEASURE and CENTS

buttons to stop the lights.

5.  Pressing the MEMORY button will show you the NOTE and OCTAVE you want to store along with the PAGE number

you have chosen.  Pressing the TUNE button will display the partial you have selected and the CENTS deviation for this

partial.

6.  Switch to MEMORY mode (by pressing the MEMORY button) to correct the NOTE or OCTAVE to be tuned on the

piano.

7.  Switch back to TUNE mode (by pressing the TUNE button) if you want to modify the partial setting.

8.  When the settings are correct, store the tuning for this note by holding down SHIFT, then pressing and releasing STO-

MEM.

9.  The Accu-Tuner will carry along the partial and the cents deviation after you store a note to memory.  All you have to

do is measure the cents deviation.  You determine cents deviation (by stopping the lights with the cents buttons) then

store the note by holding SHIFT and pressing STO-MEM.  You will notice while you are holding down the SHIFT button

just after storing a note, the display will show the NOTE/OCTAVE of the note being stored and the PAGE in memory.

Releasing the button toggles the display back to the partial and cents deviation (allowing you to check as you store the

tuning.)

10.  After you store from A0 up to around C3 you will notice the LED's will not register as clearly.  When the display starts

to become vague it is time to lower the partial.  Let's assume you were using the sixth partial and it is time to lower the

partial.  You would accomplish this by pressing the TUNE button, then use the NOTE and/or OCTAVE buttons to get the

display to the desired partial.  Next measure the cents deviation (stop the lights while playing the note).  Now before you

store this, let's double check ourselves by pressing MEM button to display the note, octave and page number.  Press the

TUNE button to display the partial and cents deviation.  If all settings are correct, then store the setting (SHIFT and STO-

MEM).
