Rechargeable batterie may be exhausted:
If the recorder has been used a lot and gone through many charge/discharge cycles the batteries may have become exhausted and no longer able to retain any charge. To fix not powering on issue replace the batteries, there are two options:

1. Replace the existing set of NIMH AAA rechargeable batteries to continue as normal.
2. If you do not have rechargeable AAA batteries to hand you can also use non-rechargeable batteries instead. If you choose this option be careful not to attempt to charge them. You may wish to change the battery type to alkaline to disable the charge facility to avoid this risk.
