Continuous recording:
Approx. 7.5 hours
Continuous play:
Approx. 12 hours
The continuous recording time is for analogue inputs when the volume level is set to
"VOL 0".
The continuous play time shows the value when the volume level is set to "VOL 15".
The above values are the standard values when the unit is charged and used at an
ambient temperature of 20°C (68°F).
The operating time when using an alkaline batteries may be different, depending on
the type and manufacturer of the battery, and on the operating temperature.
