POWER SOURCES:

The appliance should be connected to a power supply only of the

type described in the operating instructions or as marked on the appliance.

GROUNDING OR POLARIZATION:

Precautions should be taken so that the grounding

or polarization means of an appliance is not defeated.

POWER CORD PROTECTION:

Power supply cords should be routed so that they are

not likely to be walked on or pinched by items placed upon or against them, paying par-
ticular attention to cords at plugs, convenience receptacles, and the point where they
exit from the appliance.

SERVICING:

To reduce the risk of fire or electric shock, the user should not attempt to

service the appliance beyond that described in the operating instructions.  All other ser-
vicing should be referred to qualified service personnel.

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.

SAFETY INSTRUCTIONS 

NOTICE FOR CUSTOMERS IF YOUR UNIT IS EQUIPPED WITH A POWER
CORD.

WARNING: THIS APPLIANCE MUST BE EARTHED.

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 fol-
lows:

¥ 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 direct-
ly to the unit's 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.

U.K. MAINS PLUG WARNING

A moulded mains plug that has been cut off from the cord is unsafe.  Discard the
mains plug at a suitable disposal facility.  

NEVER UNDER ANY CIRCUM-

STANCES SHOULD YOU INSERT A DAMAGED OR CUT MAINS PLUG INTO
A 13 AMP POWER SOCKET. 

Do not use the mains plug without the fuse cover

in place.  Replacement fuse covers can be obtained from your local retailer.
Replacement fuses are 13 amps and MUST be ASTA approved to BS1362.

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 nec-
essary for the user to refer to the ownerÕs 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 manu-
facturerÕs 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.
