5. SETUP & POWER-ON
The RY9 can be powered by either an optional AC adaptor or six batteries.
Follow the instructions below based on the power source you intend to use.

USING A POWER ADAPTOR.

Plug the DC output cable from an optional Yamaha PA-3B AC Adaptor (available
from your Yamaha dealer) snugly into the [DC IN] jack on the rear panel, then
plug the adaptor into a convenient wall AC power outlet.
Do not attempt to use an AC adaptor other than the Yamaha PA-3B or an equivalent recommended
by Yamaha. The use of an incompatible adaptor may cause irreparable damage to the RY9, and
may even pose a serious shock hazard! ALWAYS UNPLUG THE AC ADAPTOR FROM THE AC POWER
OUTLET WHEN THE RY9 IS NOT IN USE.
When the AC adaptor plug is inserted into the RY9’s [DC IN] jack, the batteries are automatically
disconnected.
Regarding the User memory, as long as fresh batteries are inserted in (or an AC power adaptor is
connected to) the RY9, the User pattern, song and drum kit data will be retained, even when the
power is turned off. It will also be retained long enough to exchange an old set of batteries for a
new set. If you have important data in the RY9 which you don’t want to lose, please take care to
keep fresh batteries inserted in (or keep an AC power adaptor connected to) the RY9, and to
regularly save it to an external MIDI data storage device.
