correct mains plug for your local electricity network, with the earth pin connected to that 
conductor. Do not disconnect this under any circumstances, or there is a risk of severe 
or fatal electric shock. 

 

 

WARNING! 

DO NOT

 use an extension cord with the AC power cable, as if it is not correctly rated 

there is a risk of fire or electric shock. 

WARNING! 

DO NOT

 allow metallic objects or wires to enter inside the amplifier. 

 

 

WARNING! 

DO NOT

 obstruct the entries for cooling air at both the sides of the amplifier. 

Ensure that no object impedes the correct operation of the fans. 
 

 

WARNING! 

DO NOT

 expose the linear amplifier to rain, snow or any liquids. 

 

 

WARNING! 

DO NOT

 install the linear amplifier in a place without good ventilation. This could limit 

heat dissipation and the amplifier could be damaged. 
 

 

WARNING! 

DO NOT

 touch the amplifier with damp or wet hands. There is danger of electric shock. 

Avoid opening it before you have disconnected it from the mains supply, then wait at 
least 2 minutes for electrolytic capacitors to complete their discharge. 
 
 
To clean the amplifier DO NOT use chemical agents like alcohol or benzene because 
the plastic surfaces could be damaged. 
 
AVOID using the amplifier in areas with temperatures below –10° C (+14°F) or above 
+40°C (+104°F). 
 
AVOID using the linear amplifier in locations that are very dusty, damp or in direct 
sunlight. 
 
AVOID placing the linear amplifier against walls, the circulation of the air would be 
obstructed and the noise of the fans would be reflected toward the operator. 
 
AVOID permitting children to play with the amplifier. 
 
If you do not use the linear amplifier for long time, set the back main switch [I/O] to the 
OFF position [O].
