ERROR MESSAGES

No machine is unlimited, and from time to time the RX21’s LCD may present you with an error message indicating that something has gone wrong, or that you have made an operating error. These error messages are as follows:

CHANGE BATTERY!!

NO BATTERY!!!

RX BUFFER FULL!

PRESET PTN AREA!

Cause:

The RX21 memory backup battery voltage is between 1.5 and 2.2

 

V.

Solution:

Change battery as soon as possible (contact your local Yamaha

 

dealer). Press +1/YES to return LCD to normal display.

Cause:

The RX21 memory backup battery voltage is equal to or less than

 

1.5 V.

Solution:

Change battery immediately (contact your local Yamaha dealer).

Cause:

With the RX21 switched to "CH INFO AVAIL", and being “played"

 

by a MIDI keyboard or sequencer, you tried to input too much in-

 

formation (notes too rapid, and/or too many RX21 instruments played

 

simultaneously). This overloads the RX21 Buffer, and causes it to

 

go out of sync.

Solution:

Input less data (less rapid notes and/or less RX21 instruments played

 

simultaneously).

Cause 1:

You tried to edit one of the preset patterns (numbers 56-99).

Solution 1:

Copy the preset pattern (see the PATTERN COPY section) into a

 

 

programmable pattern number (00-55) and edit the copied pattern.

Cause 2:

You tried to copy a pattern onto a preset pattern number.

Solution 2: Copy the pattern into a programmable pattern number (00-55)

Cause 3:

You tried to clear a preset pattern, or clear one instrument in a preset

 

pattern.

Solution 3: No solution: preset patterns are permanently stored and cannot be modified in any way. If you wanted to alter a preset pattern by clearing one of its instruments, copy it into a programmable pattern number and clear the instrument from the copied pattern.

Cause 4: You tried to carry out a Beat Exchange operation on a preset pattern.

Solution 4: No solution: preset patterns are permanently stored and cannot be modified in any way. However, if you wanted to alter a preset pattern by carrying out a Beat Exchange operation, copy it into a programmable pattern number and carry out Beat Exchange on the copied pattern.

 

Cause:

You tried to write a pattern, copy a pattern, or carry out a Beat Exchange

 

PTN MEMORY FULL!

operation, when the pattern memory was full.

 

Solution:

Clear patterns to make space for new patterns, or save all patterns

 

 

onto cassette, then clear all patterns.
