The continuous recording time is for analogue inputs when the volume level is set to "VOL 0" (LCD edge light off).
The continuous play time shows the value when the volume level is set to "VOL 15" (LCD edge light off).
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 battery may be different, depending on the type and manufacturer of
the battery, and on the operating temperature.
