Power Supply

Your QR10 will run either from an optional AC adaptor or batteries. We recommend the use of the optional Yamaha PA-3
AC Adaptor for most applications. Follow the instructions below according to the power source you intend to use.

Using a Power Adaptor

Plug the DC output cable from an optional
Yamaha PA-3 AC Adaptor (available from your
Yamaha dealer) 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 PA-3. The use of an incompatible
adaptor may cause irreparable damage to

the QR10, and might pose a serious shock hazard!
Be sure to unplug the AC adaptor from the AC mains
outlet when the QR10 is not in use.

Using Batteries

Six 1.5V AA size (SUM-3 or R6P) or equivalent alkaline batteries must first be installed in the battery compartment. Please note
that the average life of a full set of new manganese batteries is approximately one hour or less of continuous playback at maximum
volume. Alkaline batteries may last as long as four hours. Please use an AC power adaptor (see above) wherever possible.

When to Replace the Batteries

When the batteries run down and are no longer
able to operate the QR10, playback or recording will
stop and the display shown to the right will appear:
If the battery voltage drops too low to maintain the
error display, a random, meaningless display will appear.
When these displays appear, replace the batteries
with a complete set of six new batteries. NEVER
mix old and new, or different type of batteries!
Never unplug the AC adaptor from the QR10 when a set of batteries is installed and the power is turned ON. Turn the power
