General

Power source:

 

DC 5V:

AC adaptor (AC 230 - 240V, 50/60 Hz)

DC 1.5V:

Commercially available, “AA” size (LR6), al-

 

kaline battery x 1

DC 1.2V:

Optional rechargeable Nickel-Metal Hydride

 

battery (AD-N70BT) x 1

DC 4.5V:

Optional 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)

Continuous recording:

Continuous recording:

Approx. 3 hours

Approx. 4.5 hours

Continuous play:

Continuous play:

Approx. 7 hours

Approx. 6.5 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 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.
