ATTENTION:
âą Power supply voltage polarity is extremely important. Applying power with incorrect voltage polarity could damage the
power supply and the MDA. Identify the power cord negative lead by the ridges on the side of the cord.
âą La polaritĂ© de la source dâalimentation est primordiale. Une alimentation avec une polaritĂ© de tension incorrecte peut
endommager la source dâalimentation ainsi que MDA. Il est essentiel dâidentifier une connexion nĂ©gative du cordon
dâalimentation au niveau des stries sur les parties latĂ©rales du cordon.
