SAFETY INSTRUCTIONS

NOTI CE FOR C USTOMERS IF YOUR UN IT IS EQ UIPP ED WITH A POWER CORD.

WARNING: THIS APPLIANCE SHALL BE CONNECTED TO A MAINS SOCKET OUTLET WITH A PROTECTIVE EARTHING CONNECTION.

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

GREEN and YELLOW - Earth BLUE - Neutral BROWN - Live

As colors of the cores in the mains lead of this appliance may not correspond with the colored markings identifying the terminals in your plug, proceed as follows:

•

The core which is colored green and yellow must be connected to the

terminal in the plug marked with the letter E, or with the earth symbol, or colored green, or green and yellow.

•

The core which is colored blue must be connected to the terminal

marked N or colored black.

•

The core which is colored brown must be connected to the terminal

marked L or colored 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.

DO NOT INSTALL NEA R ANY H EAT SOU RCES S UCH AS RADIATORS, HEAT R EGISTERS, STOVE S, OR OTHER AP PARATUS (INCLUDING AMPLIFIERS) THAT PRODUCE HEAT.

ONLY USE ATTACHMENTS/ACCESSORIES SPECIFIED BY THE MANUFACTURER.

UNPLUG TH IS APPA RATU S DURING LIGHTNING STORMS O R WHEN UNUSED FOR LONG PERIODS OF TIME.

Do not defeat the safet y purpose of the polarized or grounding-type plug. A polarized plug has t wo 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 w here 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 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.

POWE R ON/O FF SWI TCH: For products provided with a power switch, the power switch DOES NOT break the connection from the mains.

MAI NS DIS CONN ECT: The plug shall remain readily operable. For rack-mount or installation where plug is not accessible, an all-pole mains switch with a cont act separation of at leas t 3 mm in each pole shall be incorporated into the electrical installation of the rack or building.

FOR UNITS EQUIPPED WI TH EX TER NAL LY ACCES SIBLE FUS E RECE PTACLE: Replace fuse with same type and rating only.

MULTIPLE- INPU T VOLTAGE: T his equipment may require the use of a different line cord, attachment plug, or both, depending on the available power source at installation. Connec t 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.

IMPORTANT SAFETY INFORMATION

A molded mains plug that has been cut off from the cord is unsafe. Discard the mains plug at a suitable disposal facility. NEVER UNDER ANY CIRCUMSTANCES 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.

MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such as preampliﬁers or tape decks directly above or below the unit. Because this ampliﬁer has a high power density, it has a strong magnetic ﬁeld which can induce hum into unshielded devices that are located nearby. The ﬁeld is strongest just above and below the unit.

If an equipment rack is used, we recommend locating the ampliﬁer(s) in the bottom of the rack and the preampliﬁer or other sensitive equip ment at the top.

If you want to dispose this product, do not mix it with general household waste. There is a separate collection system for used electronic products in accordance with legislation that requires proper treatment, recovery and recycling.

Private household in the 25 member states of the EU, in Switzerland and Norway may return their used electronic products free of charge to designated collection facilities or to a retailer (if you purchase a similar new one).

For Countries not mentioned above, please contact your local authorities for a correct method of disposal.

By doing so you will ensure that your disposed product undergoes the necessary treatment, recovery and recycling and thus prevent potential negative effects on the environment and human health.
