remove stubborn grime and dirt.

Electrical Interference
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.
■
Memory Back-up
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.
■
Service and Modification
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
