IMPORTANT SAFETY INSTRUCTIONS
Read and follow instructions - All the safety and operation instructions should be read before use.
Retain instructions - These instructions should be retained for future reference.
Heed warnings - Comply with all warnings on the 540R and in the manual.
Cleaning - Unplug the 540R from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
Grounding and polarisation - The 540R may be equipped with a polarised alternating current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarised plug. (North America Only)
Overloading - Do not overload wall outlets or extension cord as this can result in a risk of fire or electric shock. Overloaded AC outlets, extension cords, frayed power cords, damaged or cracked wire insulation, and broken plugs are dangerous. They may result in a shock or fire hazard.
Power sources - The 540R should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power-supply to your home, consult your product dealer or local Power Company.
Accessories - Do not place the 540R on an unstable surface or shelf. The amp may fall, causing serious injury to a child or adult as well as serious damage to the product.
Outdoor antenna grounding - If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NIPA No. 70-1984 (section 54 of Canadian Electrical Code, Part 1) provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna- discharge unit, size of grounding conductors, location of antenna- discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.
Power cord protection - Your power supply cord should be placed so that the power lead is not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at Wall plugs and where the power lead exits from the 540R.
Contact the service department should any of these conditions occur:
When the power-supply cord or plug is damaged.
If liquid has been spilled, or objects have fallen into the amp.
If the 540R has been exposed to rain or water.
If the 540R does not operate normally after following the operation instructions, adjust only those controls that are covered by the operation instructions.
If the amp has been dropped or damaged in any way.
When the amp exhibits a distinct negative change in performance.
Servicing - Do not attempt to service the 540R yourself as removing cover may expose you to dangerous voltages or other hazards. Refer all servicing through your dealer to qualified service personnel.
Attachments - Do not use attachments not recommended by your dealer as they may cause harm to the 540R.
Lightning - For added protection during a thunderstorm, or when it is left unattended and unused for long period of time, unplug the 540R from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the 540R from lightning and power-line surges.
Heat dispersion - Leave at least 10 cm of space between the top, back and sides of the 540R and the wall or other components for proper ventilation.
Notes on use
Avoid high temperatures, allow for sufficient heat dispersion when installed on a rack.
Handle the power cord carefully. Hold the plug when unplugging the cord.
Keep the 540R free from moisture, water and dust.
Unplug the power cord when not using the 540R for long periods of time.
Do not obstruct the ventilation holes.
Do not let foreign objects, or liquids to get into the 540R.
Never disassemble or modify the 540R.
IMPORTANT
If the 540R is run at a very high level, a sensor will detect a temperature rise and show "PROTECTION OVERLOAD" on the display. The 540R will then go into stand-by. It cannot be switched on again until the temperature has fallen to a more normal level
Plug fitting instructions (UK only)
The cord supplied with the 540R is factory fitted with a 13Amp mains plug fitted with a 13Amp fuse inside. If it is necessary to change the fuse, it is important that a 13Amp one is used. If the plug needs to be changed because it is not suitable for your socket, or becomes damaged, it should be cut off and an appropriate plug fitted following the wiring instructions below. The plug must then be disposed of safely, as insertion into a 13Amp socket is likely to cause an electrical hazard. Should it be necessary to fit a 3-pin BS mains plug to the power cord the wires should be fitted as shown in this diagram. The colours of the wires in the mains lead of the 540R may not correspond with the coloured markings identifying the terminals in your plug. Connect them as follows:-
The wire which is coloured BLUE must be connected to the terminal which is marked with the letter 'N' or coloured
BLACK.
The wire which is coloured BROWN must be connected to the terminal which is marked with the letter 'L' or coloured RED
The wire which is coloured GREEN/YELLOW must be connected to the terminal which is marked with the letter 'E' or coloured GREEN.
If your model does not have an earth wire, then disregard this instruction.
