Probably NOT................. You should try a different Power Supply......Mine
likes a little more than just 9 volts for hassel free operation !
No higher than 12 volts, however !!!! Perhaps more importantly, is :
what is the current ( Amperage ) capacity of your present PS !??????
Got to be more than just a few hundred Milliamps....find one that can source 600
or more Milliamps ( 0.6 Amp ) or better...... with this parameter, the more the better...Dont worry, the Unit only draws as much as it needs, but it cannot
be starved by a PS that has insufficient source capability ! Then for sure it cannot
be expected to perform 100 % !
