Do not force the battery cover open too far. When the rechargeable battery is used for the first time or when you want to use it after a long period of disuse, be sure to charge it fully. 1 Insert the rechargeable battery. A rechargeable battery other than the AD-N55BT cannot be charged. 2 Plug the AC adaptor into the AC outlet, and then insert the plug on the other end into the DC IN 5V jack. 3 Press the MENU/CHRG button. The battery indicator will scroll, and battery will begin charging. AC 120V, 60Hz Scrolling ● After the rechargeable battery is charged or used, it To the DC IN 5V jack will get slightly warm. This is normal. ● When the portable MD is turned on or operating, the battery will not be charged. Using with the Alkaline Battery Use one commercially available alkaline battery (LR6, "AA" size). Open 2 1 Press Back of the portable MD RELEASE When using the alkaline battery, be sure to insert the rechargeable battery also. 1 2 Open the case cover. 3 Attach the battery case to the portable MD. Insert an alkaline battery into the battery case. Caution: ● While you are using the rechargeable battery and the alkaline battery at the same time, do not remove either of them. If you do, when the unit is in the play mode, playback will stop. When in the recording mode, the recorded contents will be erased, and the power may be disconnected. ● Do not replace the battery or the rechargeable battery during operation. ● Do not use a rechargeable battery (nickel-cadmium battery etc.) in the battery case. ● If the unit is not used for a long period of time, remove the battery. (Even if the power is turned off, the battery will be drained slowly but continuously.) LOCK –4– MD-MT180 Error Messages ERROR MESSAGES MEANING BATT ENPTY ● The battery has run down.

SYMPTOM LIMITATIONS "DISC FULL" or "TOC FULL" appears even though the MiniDisc still has recording time left. More than 255 tracks (maximum) cannot be recorded regardless of the recording time. If the MiniDisc is recorded or edited repeatedly or if it has scratches (recording skips scratched parts), you may not be able to record the maximum tracks above. The remaining recording time does not increase even though you erased tracks. The unit does not count non-recorded portions that last 12 or fewer seconds to display the remaining recording time. The time may not increase even if you erase short tracks. The total of the recorded time and the remaining time does not match the maximum recordable time. One cluster (approximately 2 seconds) is the minimum unit for recording. For example, a 3-second track uses 2 clusters (approximately 4 seconds). Therefore, the actual recordable time may be shorter than the displayed time. (The number of seconds indicates that in the stereo recording mode (SP). It varies depending on the recording mode.) Combine function does not work. A MiniDisc on which recording and editing are repeated may not allow the combine function. Sound skips in fast reverse/forward. If one track is divided and recorded in separate places on a repeatedly recorded or edited MiniDisc, sound may skip. A track number is created in the middle of a track. A track number may be created if there are scratches or dust on the MiniDisc. Troubleshooting Many potential "problems" can be resolved by the owner without calling a service technician. If something seems to be wrong with this product, check the following before calling your authorized SHARP dealer or service center. The unit does not turn on. Some sounds are skipped. ● Is the AC adaptor disconnected? ● Is the battery exhausted? ● Is the battery exhausted? ● Is the unit being subjected to excessive vibration? ● Is the unit in the hold mode? ● Has condensation formed inside the unit? ● Is the unit being influenced by mechanical shock or by static electricity? The MiniDisc cannot be ejected. ● Has the track number or character information been written on the disc yet? ● Is the unit in the recording or editing mode? No sound is heard from the earphones. ● Is the volume set too low? ● Is the earphones plugged in? ● Are you trying to play a MiniDisc with data on it instead of a MiniDisc containing music? When the operation buttons are pressed, the unit does not respond. ● Is the unit in the hold mode? ● Is the battery exhausted? Recording and editing are impossible. ● Is the MiniDisc protected against accidental erasure? ● Is the unit connected properly to the other equipment? ● Is the AC adaptor unplugged or did a power failure occur when recording or editing? ● Is the unit in the hold mode? ● Is an optical signal being output from the stereo system? Read the operation manual for the stereo system. ● Is the earphones plug inserted firmly? –6– MD-MT180 1 2 Connect the AC adaptor Conecte el adaptador de CA Inserting a MiniDisc Inserción de un minidisco AC 120V, 60 Hz 1 Insert according to the direction of the arrow. 120V CA, 60Hz 2 4 Insértelo de acuerdo con la dirección de la flecha. 3 1 To an AC outlet A un tomacorriente de CA To the DC IN 5V jack A la toma DC IN 5V 2 1 Plug the AC adaptor into the 1 Slide the OPEN lever to re- 3 Insert a MiniDisc as shown.

Measurement TP 0.001 – 44 – MD-MT180 TROUBLESHOOTING It is advisable to use the TEST mode (refer to Error Data Display Mode, P14) indicating the causes of troubles before starting repair. Causes of operation errors (up to 10 errors) are recorded as error codes. This information is useful for repair. When MD playback does not function When the objective lens of the optical pickup is dirty, this section may not operate. Clean the objective lens, and check the playback operation. When this section does not operate even after the above step is taken, check the following items. Remove the cabinet and follow the troubleshooting instructions. "Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup lens. Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below." Turn the power off.
