Notes
• Be sure to turn OFF the recorder before replacing the batteries. Removing the batteries while the
recorder is in use may corrupt the card. If you are recording into a file and the batteries run out, you will lose
your currently recorded file since the file header will not be written. It is crucial to replace the batteries when
one hash mark in shown in the battery icon.
• Be sure to replace both batteries at the same time.
• Never mix old and new batteries, or batteries of different types and/or brands.
• If it takes longer than 1 minute to replace dead batteries, you may have to reset the time when you load new
batteries.
• Remove the batteries if you are not going to use the recorder for an extended period of time.
