Power source:
DC 1.2V:	Rechargeable Nickel-Metal Hydride battery
	(AD-N70BT) x 1
DC 5V:	AC adaptor (AC 230 - 240V, 50/60 Hz)
DC 1.5V:	Commercially available, “AA” size (LR6), al-
	kaline battery x 1
DC 4.5V:	Separately available car adaptor, AD-CA20X
	(for cars with a 12-24V DC negative earth elec-

	trical system)
Power consumption: 7 W (AC adaptor)
Output	RMS; 20 mW (10 mW + 10 mW)
power:	(0.2% T.H.D.)
Charging	Approx. 3.5 hours (90 %)
time:	Approx. 5.5 hours (fully charged)
	(When using the AC adaptor included with the unit)

●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 20°C (68°F).

●The operating time when using an alkaline battery may be dif- ferent, depending on the type and manufacturer of the battery, and on the operating temperature.
