WARNING!
Use suitable power supply
Ensure that the supply voltage to the NV11 is not
lower than 10.8 V and that the power supply can
provide sufficient current to avoid incorrect
operation and excessive note rejects.
We recommend that your power supply is capable of supplying 12V DC at 4 A.
 For 12V operation, use TDK Lambda model SWS50-12. This power supply is
available from a variety of suppliers including Farnell (stock code 1184645) and
RS (stock code 466-5869).
