15. WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. The apparatus

shall not be exposed to dripping or splashing and that objects filled with liquids, such as vases, shall not be placed

on apparatus

16. Never set the amplifier on a support that might give out under its weight.

17. WARNING: The mains plug used as disconnect device, the disconnect device shall remain readily operable.

18. 

Protective earthing terminal. The apparatus should be connected to a mains socket outlet with a protective

earthing connection.

19. Replace fuse with rated value, never bridge defective fuses. Before changing fuse disconnect power cable from unit!

20. 

Correct Disposal of this product. This marking indicates that this product should not be disposed with other

household  wastes  throughout  the  EU.  To  prevent  possible  harm  to  the  environment  or  human  health  from

uncontrolled waste disposal, recycle it responsibly to promote the sustainable reuse of material resources. To return

your  used  device,  please  use  the  return  and  collection  systems  or  contact  the  retailer  where  the  product  was

purchased. They can take this product for environmental safe recycling.

PRODUCT SHOULD BE SERVICED BY QUALIFIED PERSONNEL WHEN:

1. 

Unit has been dropped or the enclosure damage.

2. 

Mains switch has been damaged.

3. 

Objects or liquids have penetrated the unit.

4. 

Unit does not operate normally and troubleshooting (last chapter of this manual) does not help.

PROTECTIVE CIRCUITS

Your  new  Warwick  amplifier  is  equipped  with  a  series  of  circuits  to  prevent  it  from  destruction  in  case  of  inadequate

operating conditions:

POWER-UP DELAY:

When the unit is switched on, the SPEAKER OUT sockets are activated with a slight delay to protect

the loudspeakers.

SHORT-CIRCUIT:

This feature prevents the output stage transistors from destruction by quickly reducing current in the

case of short-circuit at the power amp outputs.

DIRECT  CURRENT  (DC):

This  circuit  continuously  monitors  the  power  amp  output  for  direct  current  and  protects  the

loudspeakers from overload.

HF OSCILLATION: 

By switching the power amp off, this safety feature prevents from damages that could be caused by

frequencies in excess of 20 kHz (feedback, etc.).

EXCESSIVE TEMPERATURES: 

This circuit protects the output stage transistors from destruction by switching the device

off if the temperature-regulated fan cooler prove to be insufficient and temperature of device will be too high.

NOTE: 

You can recognize that one of these circuits has been activated as a result of a fault, when the MUTE

LED glows continuously even though you have not selected the MUTE mode. In case of short-circuit please

check the speaker cable. The amplifier must then be switched off and on again to get back into playing mode

after having removed short-circuits. In any other situation the amplifier switches automatically back to playing

mode as soon as it detects the fault has disappeared (e.g. the amplifier has overheated and cooled down again).
