Instruccions de funcionament
This adapter provides continuous power to your RadioShack MD-1121 Portable Piano Keyboard. It is not designed for charging rechargeable batteries within the device, but rather to power the device directly. If your device uses rechargeable batteries, the adapter will power the device while connected, but the batteries themselves may not charge if the device's internal charging circuit is not active or if the batteries are beyond their lifespan.

- Keep the adapter clean and free from dust. Use a dry, soft cloth for cleaning.
- Guardeu l'adaptador en un lloc fresc i sec quan no l'utilitzeu.
- Avoid bending or crimping the power cord excessively to prevent internal damage.

- Assegureu-vos que l'adaptador estigui ben connectat tant al dispositiu com a la presa de corrent.
- Verify the wall outlet is functional by testing it with another appliance.
- Confirm that your device is indeed a RadioShack MD-1121. This adapter is model-specific.
- If your device uses rechargeable batteries, and it still doesn't power on, the batteries might be old or dead and unable to hold a charge, even if the adapter is supplying power. This adapter powers the device, but does not fix dead batteries.
L'adaptador s'escalfa durant l'ús:
It is normal for power adapters to become slightly warm during operation. If the adapter becomes excessively hot or emits a burning smell, immediately unplug it from the wall outlet and discontinue use. Contact customer support.
