Thank you for purchasing the Korg Tuner
Metronome Recorder TMR-50.
Main features
The TMR-50 allows you to record and tune
using the internal mic or a mic connected to
the INPUT jack. Additionally, you can use
the recorder, tuner and metronome either
separately or simultaneously.
Installing batteries
Before replacing the baeries, make sure

the back of the TMR-50 in direction “a”
as shown in the illustration and li up
the cover in direction “b.”
2. Insert the batteries, making sure to
observe the correct polarity.
3. In order to get accurate readings of the
remaining baery power, please refer
to the “Seing the baery type” section
on page 7 and select the type of baery
that’s being used.
Depleted baeries should be immediately
removed from the unit. In addition, remove

When the baeries run down even further,
the baery symbol will blink. At this time, it
will no longer be possible to use the recorder
function to record. Although you will still be
able to play back recorded data and use the
tuner and metronome functions, you should
replace the baeries as soon as possible.
Setting the battery type
In order to get accurate readings of the
remaining baery power, select the type of
