The symbols shown above are internationally accepted symbols that warn of 

potential hazards with electrical products. The lightning flash with arrowpoint in 

an equilateral triangle means that there are dangerous voltages present within 

the unit. The exclamation point in an equilateral triangle indicates that it is 

necessary for the user to refer to the owner’s manual.

These symbols warn that there are no user serviceable parts inside the unit. 

Do not open the unit. Do not attempt to service the unit yourself. Refer all 

servicing to qualified personnel. Opening the chassis for any reason will void 

the manufacturer’s warranty. Do not get the unit wet. If liquid is spilled on the 

unit, shut it off immediately and take it to a dealer for service. Disconnect the 

unit during storms to prevent damage.

THE MANUFACTURER’S INSTRUCTIONS.

DO NOT INSTALL NEAR ANY HEAT SOURCES SUCH AS RADIATORS, HEAT REGISTERS, 

STOVES, OR OTHER APPARATUS (INCLUDING AMPLIFIERS) THAT PRODUCE HEAT.

ONLY USE ATTACHMENTS/ACCESSORIES SPECIFIED BY THE MANUFACTURER.

UNPLUG THIS APPARATUS DURING LIGHTNING STORMS OR WHEN UNUSED FOR LONG 

PERIODS OF TIME.

Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized 

plug has two blades with one wider than the other. A grounding type plug has two 

blades and a third grounding prong. The wide blade or third prong are provided for your 

safety. If the provided plug does not fit your outlet, consult an electrician for replace-

ment of the obsolete outlet.

Protect the power cord from being walked on or pinched particularly at plugs, conve-

nience receptacles, and the point where they exit from the apparatus.

Use only with the cart stand, tripod bracket, or table specified by the manufacture, 

or sold with the apparatus. When a cart is used, use caution when moving the cart/

apparatus combination to avoid injury from tip-over.

Refer all servicing to to qualified service personnel. Servicing is required when the ap-

paratus has been damaged in any way, 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.

POWER ON/OFF SWITCH: The Power switch used in this piece of equipment DOES NOT 

break the connection from the mains.

MAINS DISCONNECT: The plug shall remain readily operable. For rack-mount or instal-

lation where plug is not accessible, an all-pole mains switch with a contact separation 

of at least 3 mm in each pole shall be incorporated into the electrical installation of the 

rack or building.

If connected to 240V supply, a suitable CSA/UL certified power cord shall be used for 

this supply.

This Equipment is intended for rack mount use only.
