●
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
25
°
C (77
°
F).
●
The operating time when using an alkaline battery
may be different, depending on the type and manufac-
turer of the battery, and on the operating temperature.
