IMPORTANT SAFETY INSTRUCTIONS
& EXPLANATION OF SYMBOLS
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the
presence of uninsulated “dangerous” voltage within the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to humans.
The exclamation point within an equilateral triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in this manual.
Your SRA amplifier has a serial number located on the rear panel, near the AC
cord entry. It looks like the example at right. Please write the serial number

such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
15- When installing equipment into a rack, distribute the units evenly. Otherwise, hazardous conditions may be
created by an uneven weight distribution.
16- Connect the unit only to a properly rated supply circuit.
