WARNINGS AND CAUTIONS 

WARNING

 statement calls attention to an operating procedure, 

practice, or condition, which, if not followed correctly, could result in 
injury or death to personnel. 

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. 

WARNING

:  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.
