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 manufacturer of the battery,
and on the operating temperature.
The setting for the REMOTE LCD is set to "AUTO OFF".
Specifications for this model are subject to change without prior
notice
