It indicates a potentially hazardous situation, which, if mishandled, could re-

sult in minor or moderate damage to the person and/or property damage.

The safety symbols and messages described below are used in this manual to prevent personal 

injury and property damage, which could be the improper use. Before putting the product into opera-

tion, read this manual and understand the safety symbols and messages, in order to be fully aware 

of the potential risks.

•  Do not expose the unit to rain or an environment where it could be wet by water and/or other 

liquids, since in this way could cause fire or electric shock.

• 

Use this device only with the voltage specified on the unit. Using a higher voltage than specified 

may result in fire or electric shock.

•  Do not cut, bend, damage, or modify the power cord. Also, avoid using the power cord in the vici-

nity of heat sources and never place heavy objects (including the unit itself), on the power cord, 

since in this way could cause fire or electric shock.

•  Be sure to replace the protective cover of the connection terminals once it has been completed. 

Because the speaker connections are of high voltage, never touch these terminals to avoid 

electric shock.

•  Make sure the connection to the ground terminal is correctly made, in order to avoid electric 

shock.

•  Do not install or mount the device in an unstable position, such as on a wobbly table or on an 

inclined surface. Could lead to the fall of the amplifier and cause injury and/or property damage.
