When recording with built-in stereo microphone (using internal memory)

Recording mode		Alkaline dry cell battery	Nickel-metal hydride rechargeable battery
Linear PCM format	48.0 kHz / 16 bit	26 hours (approx.)	20 hours (approx.)
	44.1 kHz / 16 bit	28 hours (approx.)	21 hours (approx.)
MP3 format	320 kbps	31 hours (approx.)	22 hours (approx.)
	128 kbps	35 hours (approx.)	25 hours (approx.)

	8 kbps mono	52 hours (approx.)	38 hours (approx.)

• 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.

• Actually available recording times may be shorter than the figures shown here when making short recordings repeatedly (Equipment displays of available/elapsed recording times should beconsidered guideline values).
• Available recording time will also vary due to differences in the available memory capacity of different microSD cards.

Recording mode		Recording time
Linear PCM format	48.0 kHz/16 bit	3 hours (approx.)
	44.1 kHz/16 bit	3 hours, 20 minutes (approx.)
MP3 format	320 kbps	29 hours, 40 minutes (approx.)
	128 kbps	74 hours, 30 minutes (approx.)
	64 kbps mono	149 hours (approx.)
	8 kbps mono	1193 hours (approx.)

• The maximum file size is limited to about 4GB in the MP3 format, and to about 2 GB in the linear PCM (WAV) format.
• Regardless of the amount of remaining memory, the maximum recording time per file is restricted to the following values.
