INFORMATION 

 

Your new kW Phono is designed and built to provide trouble-free performance, but as with all 
electronic devices it is necessary to observe a few precautions: 
 
Heed all warnings shown on the back of the product. 
 
Only connect the kW Phono to a mains outlet having the same voltage as marked at the back of the 
unit. 
 
Always ensure that when disconnecting and reconnecting your audio equipment the mains supply 
is switched off. 
 
Position the mains lead and signal interconnects where they are not likely to be walked on or 
trapped by items placed on them. 
 
Do not use near water, or place water-filled containers on the pre-amplifier, for example, a flower 
vase or potted plants.  

If water does spill inside, immediately pull out the mains plug from the

 

wall socket and inform your dealer, who should then check the unit before further use. 
Entry of liquid into the preamplifier is dangerous, and may cause electric shock or fire 
hazard. 

 
Do not place the unit near direct heat sources such as radiators, direct sunlight or other equipment. 
 
Do not remove any covers or try to gain access to the inside.  There are no internal adjustments or 
fuses you can replace yourself.  Refer all service work to an authorised Musical Fidelity agent. 

 
Note: Unauthorised opening of the equipment will invalidate any warranty claim. 

 
Dust regularly with a soft cloth or soft brush but be careful when using cleaning or polishing agents 
- they may harm the surface finish. 
 
The electronics in modern hi-fi equipment is complex and may, therefore, be adversely affected or 
damaged by lightning. For protection of your audio system during electrical storms, remove the 
mains plugs and disconnect any aerial lead. 
 
If after-sales service is required, to help your dealer identify the kW Phono pre-amplifier please 
quote the serial number located on the rear panel of the unit. 
 
 

RADIO  FREQUENCY  INTERFERENCE  (R.F.I) 

 
This product has been tested to ensure that its operation is not adversely affected by normal 
background levels of R.F.I., and that it does not itself generate excessive amounts of interference. 
However, if a problem persists, please contact your Musical Fidelity agent.
