HEED ALL WARNINGS

FOLLOW ALL INSTRUCTIONS

THE APPARATUS SHALL NOT bE ExPOSED TO DRIPPING OR SPLASHING 

LIqUID AND NO ObjECT FILLED WITHI 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 AC-

CORDANCE WITH THE  MANUFACTURER’S  INSTRUCTIONS.

DO NOT INSTALL NEAR ANY HEAT SOURCES SUCH AS RADIATORS, 

HEAT REGISTERS, STOvES, OR OTHER APPARATUS (INCLUDING AMPLI-

FIERS) THAT PRODUCE HEAT.

ONLY USE ATTACHMENTS/ACCESSORIES SPECIFIED bY THE MANUFAC-

TURER.

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 out-

let, 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 manufac-

ture, 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 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: If the equipment has a Power 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 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 RECEP-

TACLE:    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 servic-

ing to qualified service personnel or equivalent.

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

used for this supply.

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 correspond 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 plug, or both, 

depending on the available power source at installation.  if the attachment plug needs to be 

changed, refer servicing to qualified service personnel who should refer to the table below. the 

green/yellow wire shall be connected 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 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 lightning flash with arrow-

point in an equilateral triangle means that there are dangerous voltages pres-

ent 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.
