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 replacement of the obsolete outlet.

Protect the power cord from being walked on or pinched particularly at plugs, convenience
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 combi-
nation to avoid injury from tip-over.

Refer all servicing to to qualified service personnel.  Servicing is required when the appara-
tus 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: For products provided with a power switch, the power switch  DOES
NOT break the connection from the mains.

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

FOR UNITS EQUIPPED WITH EXTERNALLY ACCESSIBLE FUSE RECEPTACLE:    Replace fuse with
same type and rating only.

MULTIPLE-INPUT VOLTAGE: This equipment may require the use of a different line cord, attach-
ment plug, or both, depending on the available power source at installation. Connect this equip-
ment only to the power source indicated on the equipment rear panel. To reduce the risk of
fire or electric shock, refer servicing to qualified service personnel or equivalent.

ed directly to the units chassis. 

WARNING: If the ground is defeated, certain fault conditions in the unit or in the system to which it is con-

result if the chassis and earth ground are touched simultaneously.

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
