Continuous play: Approx. 52 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 vol-
ume level is set to "VOL 15".
The above values are the standard values when the unit is
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 manufacturer of the
battery, and on the operating temperature.
Specifications for this model are subject to change without prior
notice
