The RY20 contains digital circuitry and may cause interference or noise if placed too close to 
TV sets, radios, or similar equipment. If such a problem does occur, move the RY20 further 
away from the affected equipment.

The RY20 contains a special long-life battery that retains the contents of its internal RAM 
memory even when the power is turned OFF. The back-up battery should last for several 
years. When the back-up battery needs to be replaced, the message “

BATT LOW

” will 

momentarily appear on the display when you turn the power ON. When this happens, have 
the back-up battery replaced by qualified Yamaha service personnel.

Transfer important data from your RY20 to a MIDI data recorder such as the Yamaha MDF2 
MIDI Data Filer for safe long-term storage. Yamaha cannot be held responsible for data loss 
caused by battery failure or improper operation of the RY20.

■

The RY20 contains no user-serviceable parts. Opening the case and/or tampering with the 
internal circuitry can lead to irreparable damage and will void the warranty. Refer all 
maintenance to qualified Yamaha service personnel.
