Selecting the recording quality
For the user who does not utilize the maximum recording capacity
(about 18 minutes), you can select a higher recording grade and enjoy
superior sound quality and clarity compared to the standard (NORM)
grade. As higher sound quality uses up more memory capacity, the
maximum recording time changes accordingly.
Note
The approx. length of the three recording grades are:
HIGH (Short) – 8 minutes
MID – 11 minutes
NORM (Long) – 18 minutes
Actual recording time may vary.
