Yamaha DSP-A970 - Manual (Page 40)

NOTE: The originally preset function of a key is still available in the
USER position if the key does not learn a new function.
NOTE: If all signals learned are long signals, it is possible that the
capacity of the memory could be completely filled before all of the
keys learn new functions, and so no further learning is possible.
The function learned by any key can be easily changed by
repeating the learning process with a different function. It is also
possible to erase learned functions so that the keys return to the
originally preset functions.
Erasing a Learned Function
1. Set the YPC/USER/LEARN switch to “USER”.
2. Use the point of a pencil or other similar object to press and hold
the CLEAR button.
3. Press and hold the key whose function is to be erased until the
TRANSMIT/LEARN indicator flashes on and off three times.
Erasing All Learned Functions
1. Set the YPC/USER/LEARN switch to “LEARN”.
2. Use the point of a pencil or other similar object to press and hold
the CLEAR button.
3. Press and hold any key until the TRANSMIT/LEARN indicator
flashes on and off seven times.
NOTE: All of the memorized functions will be retained while you
replace the batteries. However, if no batteries are installed for a few
hours, the memory will be erased and will have to be programmed
again.
NOTE: There may occasionally be instances in which, due to the
signal-coding and modulation systems employed by the other remote
control unit, that this unit will not be able to learn its signals.
NOTE: When the remote control freezes, press the RESET button on
the rear of the main unit to “reset” the internal microcomputer which
controls remote control operations.
Pressing the RESET button will not erase learned functions.
