MD-MS722/C/W/MS721W FOR A COMPLETE DESCRIPTION OF THE OPERATION OF THIS UNIT, PLEASE REFER TO THE OPERATION MANUAL. SPECIFICATIONS General Power source: (MS722/MS722C) Power source: (MS722W/MS721W) Power consumption: (MS722/MS722C) Power consumption: (MS722W/MS721W) Output power: Charging time: Battery life: DC 3.6 V (rechargeable lithium-ion battery x 1) DC 5 V (AC adaptor) AC 120V, 60 Hz DC 3.4V: Battery case (commercially available, "AA" size, alkaline battery x 1) DC 4.5V: Separately available car adaptor, AD-CA20X (for cars with a 12-24V DC negative earth electrical system) DC 3.6 V (rechargeable lithium-ion battery x 1) DC 5 V (AC adaptor) AC 110 - 240V, 50/60 Hz DC 3.4V: Battery case (commercially available, "AA" size, alkaline battery x 1) DC 4.5V: Separately available car adaptor, AD-CA20X (for cars with a 12-24V DC negative earth electrical system) 7 W (AC adaptor) 0.15A (AC adaptor) RMS; 20 mW (10 mW + 10mW) (0.2% T.H.D.) Approx. 3 hours (When using the AC adaptor included with the unit) When using the rechargeable battery (fully charged) included with the unit When using one, commerically available, high capacity, "AA" size, alkaline batteries (in the battry case) When using one, commercially available, high capacity, "AA" size batteries with the rechargeable battery (fully charged) Continuous recording: Approx. 8 hours Continuous recording: Approx. 3 hours Continuous recording: Approx. 11 hours Continuous play: Approx. 10 hours Continuous play: Approx. 6 hours Continuous play: Approx. 16 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 20oC. The operating time when using alkaline batteries may be different, depending on the type and manufacturer of the batteries, and on the operating temperature.
