DC 4.5V: Separately available car adaptor,
Power source: DC 3.6 V (rechargeable lithium-ion
(MS722W/MS721W)
DC 5 V (AC adaptor)
AC 110 - 240V, 50/60 Hz
DC 3.4V: Battery case
DC 4.5V: Separately available car adaptor,
Power consumption: 7 W (AC adaptor)
(MS722/MS722C)
Power consumption: 0.15A (AC adaptor)
(MS722W/MS721W)
Output power: RMS; 20 mW (10 mW + 10mW)
(0.2% T.H.D.)
Charging time: Approx. 3 hours
(When using the AC adaptor included
with the unit)
Battery life:
When using one,
When using the
commerically available,
rechargeable battery (fully
high capacity, "AA" size,
charged) included with the
alkaline batteries (in the
unit
battry case)
Continuous recording:
Continuous recording:
Approx. 3 hours
Approx. 8 hours
Continuous play:
Continuous play:
Approx. 6 hours
Approx. 10 hours
The continuous recording time is for analogue input 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
The operating time when using alkaline batteries may be different,
depending on the type and manufacturer of the batteries, and on the
operating temperature.
