MD-S301H Ð 2 Ð Headphones Ñ 5 mW + 5 mW 32 ohms LINE 250 mV (-12 dB) Ñ 50 kohms Output level: Dimensions:Width: 87 mm (3-7/16") Height: 24 mm (31/32") Depth: 78 mm (3-3/32") Weight:184 g (0.41 lbs.) with rechargeable battery Output socket:Headphones (impedance: 32 ohms)/ remote control unit Mini Disc Player Type:Portable MiniDisc player Signal readout:Non-contact, 3-beam semi-coductor laser pick-up Audio channels:2 Frequency response:20 - 20,000 Hz (± 3 dB) Rotation speed:Approx. 400 - 900 rpm Error correction:ACIRC (Advanced Cross Interleave Reed-Solomon Code) Coding:ATRAC (Adaptive TRansform Acoustic Coding) D/A converter:1 bit Sampling frequency:44.1kHz Modulation system:EFM (Eight to Fourteen Modulation) Wow and flutter:Unmeasurable (less than ±0.001% W.peek) SAFETY PRECAUTION FOR SERVICE MANUAL Precaution to be taken when replacing and servicing the Laser Pickup. The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class I Requirements. However, the following precautions must be observed during servicing to protect your eyes against exposure to the Laser:- (1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position outer than the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens. (2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to shipping. (3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup. (4) Under no circumstances look directly into the Pickup Lens at any time. (5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result in hazardous radiation exposure. Laser Diode Properties Material: GaAIAs Wavelength: 785 nm Emission Duration: continuous Laser Output: max. 0.73 mW SPECIFICATIONS General Power source: DC 3.6 V (rechargeable lithium-ion battery x 1)DC 5 V (AC adaptor) AC 110 - 240 V, 50/60 Hz DC 1.5 V: Separately available battery case, AD-S30BC (commercially available, "AA" size, alkaline battery x 1) DC 4.5 V: Separately available car adaptor, AD-CA20X ( for cars with a 12-24V DC negativeearth electrical system) Power consumption:0.15 A (AC adaptor) 4 W Output power:RMS; 10 mW (5 mW + 5 mW) (0.2 % T.H.D.) Charging time:Approx. 3 hours (When using the AC adaptor included with the unit) Battery life: Volume level: "VOL 15" The above values are the standard values when the unit is charged and used at an ambient temperature of 20 ûC. The playing time when using an alkaline battery may be different, depending on the type and manufacturer of the battery and on the operating temperature.
