Notes
• Manganese battery may not be used in this recorder.
• Be sure to stop the recorder before replacing the battery. Unloading the battery while the recorder
is in use may corrupt the file. If you are recording into a file and the battery runs out, you will lose your
currently recorded file because the file header will not be able to close. It is crucial to change the battery
once you see only one hash mark in the battery indicator.
• If it takes longer than 15 minutes to replace the dead battery or if you take the battery in and out
repeatedly at short intervals, you may have to reset the time when you have loaded a fresh battery.
• Remove the battery if you are not going to use the recorder for an extended period of time.
• When playing a voice/music file, the recorder may be reset due to the reduction of the voltage output of
the battery depending on the volume level even if
is displayed in the battery indicator. In this case,
lower the volume of the recorder.
