Safety Instructions
OVERHEATING
This amplifier is intended for use in moderate climates only. It should not be used in tropical
regions. The recommended ventilation clearances and other precautions given in the relevant
section of this instruction leaflet should be observed to prevent overheating. No unit should be
fixed where it is likely to become smothered by soft furnishing fabrics such as curtains, or by
thermal insulation material in a roof space or building void. Mains powered equipment should
not be left resting on a carpet.
WATER AND FIRE RISKS
The appliance is not waterproof. It is intended for indoor use only and must not be fixed where
it could be exposed to dripping or splashing water. Objects containing liquids should not be
placed on or near the appliance. To prevent risk of fire, no object with a naked flame should be
placed on or near the appliance, or its associated wiring.
MAINS PLUG AND DISCONNECTION FROM THE SUPPLY
The appliance is supplied with a standard fused plug fitted. If this is unsuitable, refer to the
instructions below. If you need to change the fuse in the fitted plug, a 3 Amp fuse to BS 1362
carrying the ASTA or BSI approval mark must be used. Always replace the plastic fuse carrier
when renewing the fuse. The plug (or other means of disconnection from the supply, if used)
should remain readily accessible for operation when necessary. The LED power indicator on
this equipment should not be regarded as providing reliable indication of supply disconnection.
CHANGING THE PLUG
If the fitted mains plug is not suitable for the socket-outlets in use, it should be cut off and a
new plug fitted.
Wiring the new plug:
Instructions supplied with the new plug should be followed. The brown
wire must be connected to the live (L) terminal of the plug and the blue wire to the neutral (N)
terminal. Neither wire should be connected to the earth (E) terminal of a 3-pin plug (the
appliance does not require an earth connection). Ensure that the cord grip in the plug is correctly
used and clamps the sheath of the cord firmly.
Fuse Rating:
If the new plug is a fused type, the fuse fitted should be rated at not more than
3 Amp.
Caution:
The old plug should be destroyed immediately since it would be dangerous if plugged
into a live socket.
