Recoding(centre microphone OFF)		60 Hz – 20 kHz

• Frequency response upper limit is set by recording mode during MP3-format recording.

• During playback

20 Hz – 20 kHz

• The upper and lower limit values of the frequency response depend on each recording format.

• Battery life

• The battery life figures shown here were determined using an Olympus test method (When [Mic Select] is set to [Central Mic Off], and [LED] is set to [Off]). Actual batterylife figures will vary greatly according to the battery used and usage conditions (Changing the playback speed or using the [Zoom Mic], [Noise Cancel] and [Voice Balancer] functions may affect the battery life).
• Battery life will be shorter when using a nickel-metal hydride rechargeable battery that has been used repeatedly.
• Battery life will be shorter when using a microSD card.
