THE APPARATUS SHALL NOT BE EXPOSED TO DRIPPING OR 

SPLASHING LIQUID AND NO OBJECT FILLED WITH LIQUID, SUCH 

AS VASES, SHALL BE PLACED ON THE APPARATUS

CLEAN ONLY WITH A DRY CLOTH.

DO NOT BLOCK ANY OF THE VENTILATION OPENINGS. INSTALL IN 

ACCORDANCE WITH 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 

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 combination to avoid injury 

from tip-over.  Refer all servicing to to qualified service personnel. 

Servicing is required when the apparatus 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, attachment plug, or both, depending on the 

available power source at installation. Connect this equipment 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.

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

be used for this supply.

SAFETY INSTRUCTIONS 

NOTICE FOR CUSTOMERS IF YOUR UNIT IS EQUIPPED WITH A 

POWER CORD.

SOCKET OUTLET WITH A PROTECTIVE EARTHING CONNECTION.

The cores in the mains lead are coloured in accordance with the following code:

GREEN and YELLOW - Earth        BLUE - Neutral        BROWN - Live

As colours of the cores in the mains lead of this appliance may not cor-

respond with the coloured markings identifying the terminals in your plug, 

proceed as follows:
•  The core which is coloured green and yellow must be connected to the 

terminal in the plug marked with the letter E, or with the earth symbol, or 

coloured green, or green and yellow.

•  The core which is coloured blue must be connected to the terminal 

marked N or coloured black.

•  The core which is coloured brown must be connected to the terminal 

marked L or coloured red.

 

This equipment may require the use of a different line cord, attachment

WARNING: If the ground is defeated, certain fault conditions in the unit or 

in the system to which it is connected can result in full line voltage between 

chassis and earth ground. Severe injury or death can then 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 light-
ning flash with arrowpoint in an equilateral triangle means that 
there are dangerous voltages present within the unit. The exclama-
tion 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.
