IMPORTANT
- Be sure to comply with the “Safety Precautions” provided in the separate “READ THIS!” sheet. Incorrect use of this product creates the risk of electric shock and fire.
- Always make sure that the Digital Keyboard is turned off before plugging in or unplugging the AC adaptor, or before loading or removing batteries.
Using a Household Power Outlet
Make sure that you use only the AC adaptor specified for this keyboard. Use of a different type of AC adaptor can cause malfunction.

IMPORTANT
- The AC adaptor will become warm to the touch after very long use. This is normal and does not indicate malfunction.
- To prevent breaking of the wire, take care to avoid putting any type of load on the power cord.

Using Batteries
Use 6 commercially available size AA alkaline batteries or NiMH rechargeable batteries.
- Commercially available size AA manganese batteries can also be used, but because some types of usage may require high power consumption, the use of alkaline batteries or NiMH rechargeable batteries is recommended.
Note the precautions below when using rechargeable batteries.
- Use Panasonic Group AA-size eneloop rechargeable batteries. Do not use any other type of batteries.
- Use only the specified charger to charge batteries.
- Rechargeable batteries must be removed from the product for charging.
