WARNINGS AND CAUTIONS 
WARNING and CAUTION statements, such as the following examples, 
denote a hazard and appear throughout this manual. Follow all instructions 
contained in these statements. 
A WARNING statement calls attention to an operating procedure, practice, 
or condition, which, if not followed correctly, could result in injury or death 
to personnel. 
A CAUTION statement calls attention to an operating procedure, practice, or 
condition, which, if not followed correctly, could result in damage to or 
destruction of parts or the entire product. 
WARNING: 
Do not alter the ground connection. Without the protective 
ground connection, all accessible conductive parts (including 
control knobs) can render an electric shock. The power jack 
and mating plug of the power cable meet IEC safety standards.

To avoid electrical shock hazard, disconnect power cord before 
removing covers. Refer servicing to qualified personnel. 
CAUTION: 
Before connecting the line cord to the AC mains, check the rear 
panel AC line voltage indicator. Applying a line voltage other 
than the indicated voltage can destroy the AC line fuses. For 
continued fire protection, replace fuses only with those of the 
specified voltage and current ratings. 
CAUTION: 
This product uses components which can be damaged by 
electro-static discharge (ESD). To avoid damage, be sure to 
follow proper procedures for handling, storing and 
transporting parts and subassemblies which contain ESD-
sensitive components.
