Battery life:
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
o
C.
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.
