5. How to reset the product
When the product is POWER ON, press 3 buttons [ TUNING▲+ CLEAR + MEMO ] simultaneously.
FLD shows “DEFAULT”, then all memories are cleared. And the product will be STAND-BY status.
This adjustment is normally not necessary, because the coil LA06 is preset by the original supplier
