MD-SR60
FOR A COMPLETE DESCRIPTION OF THE OPERATION OF THIS UNIT, PLEASE REFER TO
THE OPERATION MANUAL.
General
Power source: DC 1.2V: Rechargeable Nickel-Metal Hydride
battery (AD-N70BT) x 1
DC 5V : AC adaptor (AC 120V, 60 Hz)
DC 1.5V: Commercially available, "AA" size
(LR6), alkaline battery x 1
DC 4.5V: Separately available car adaptor,
AD-CA20X (for cars with a 12-24V
DC negative ground electrical
system)
Power consumption: 7W (AC adaptor)
Output power: RMS; 20 mW (10 mW + 10 mW) (0.2 % T.H.D.)
Charging time: Approx. 3.5 hours (90%)
Approx. 5.5 hours (fully charged)
(When using the AC adaptor included with the unit)
Battery life:
When using a commercially available,
high capacity, "AA" size (LR6),
alkaline battery
Continuous recording
Approx. 3 hours
Continuous play
Approx. 7 hours
The continuous recording time is for analog 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 68˚F (20˚C).
The operation time when using an alkaline battery may be
different, depending on the type and manufacturer of the battery
and on the operating temperature.
