Important safety instructions
Please take a moment to read these notes before installing your 540R
v3, as they will enable you to get the best performance and prolong the
life of the unit. We advise you follow all instructions, heed all warnings
and keep the instructions for future reference.
Ventilation
IMPORTANT - The unit will become hot when in use.
Please ensure there is ample ventilation (at least 10cm clearance all
round). Do not put any objects on top of this unit. Do not situate it on a
rug or other soft surface and do not obstruct any air inlets or outlet
grilles. Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers) that produce
heat. Do not stack multiple units on top of each other. Do not place in
an enclosed area such as a bookcase or in a cabinet without sufficient
ventilation.
Do not obstruct the rear heat tunnel ventilation grille. Ensure that small
objects do not fall through any ventilation grille. If this happens, switch
off immediately, disconnect from the mains supply and contact your
dealer for advice.
Positioning
Choose the installation location carefully. Avoid placing it in direct
sunlight or close to a source of heat. Also avoid locations subject to
vibration and excessive dust, cold or moisture. Do not place the unit on
an unstable surface or shelf. The unit may fall, causing serious injury to
a child or adult as well as serious damage to the product. Do not place
a CD player or other equipment on top of the unit.
This unit must be installed on a sturdy, level surface. Do not
place in a sealed area such as a bookcase or in a cabinet. Any
space open at the back (such as a dedicated equipment rack)
is fine however. When a cart is used, use caution when moving
the cart to avoid injury from tip-over.
WARNING - To reduce the risk of fire or electric shock, do not expose this
unit to rain or moisture. This unit must not be used near water or
exposed to dripping or splashing water or other liquids. No objects filled
with liquid, such as vases, shall be placed on the unit. In the event,
switch off immediately, disconnect from the mains supply and contact
your dealer for advice.
Electronic audio components have a running in period of around a week
(if used several hours per day). This will allow the new components to
settle down, the sonic properties will improve over this time.
Grounding and polarisation
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.
Power sources
The unit 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.
This unit has been designed to be left in Standby mode when not in use,
this will increase the life of the amplifier (this is true with all electronic
equipment). To turn the unit off completely switch off on the rear panel.
If you do not intend to use this unit for a long period of time, unplug it
from the mains socket.
Power cord protection
The unit must be installed in a manner that makes disconnection of the
mains plug from the mains socket outlet (or appliance connector from the
rear of the unit) possible. Where the mains plug is used as the disconnect
device, the disconnect device shall remain readily operable. Protect the
power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the unit.
Be sure to insert each power cord securely. To prevent hum and noise, do
not bundle the interconnect leads with the power cord or speaker leads.
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.
Lightning
For added protection during a thunderstorm, or when it is left
unattended and unused for long period of time, unplug the unit from the
wall outlet and disconnect the antenna or cable system. This will prevent
damage to the unit from lightning and power-line surges.
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.
Cleaning
To clean the unit, wipe its case with a dry, lint-free cloth. Do not use any
cleaning fluids containing alcohol, ammonia or abrasives. Do not spray
an aerosol at or near the amplifier.
Attachments
Do not use attachments not recommended by your dealer as they may
cause harm to the unit. Only use the specified attachments/accessories
with this unit.
Servicing
These units are not user serviceable, never attempt to repair,
disassemble or reconstruct the unit if there seems to be a problem. A
serious electric shock could result if this precautionary measure is
ignored. In the event of a problem or failure, please contact your dealer.
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 unit has been exposed to rain or water.
- If the unit does not operate normally after following the operation
instructions, adjust only those controls that are covered by the
operation instructions.
- If the unit has been dropped or damaged in any way.
- When the unit exhibits a distinct negative change in performance.
IMPORTANT
If the unit is run at a very high level, a sensor will detect a temperature
rise and show "PROTECTION OVERLOAD" on the display. The unit will
then go into Standby mode. It cannot be switched on again until the
temperature has fallen to a more normal level.
