INSTALLATION  PRECAUTIONS  and  USER  INFORMATION

Your new kW 500 Integrated amplifier is designed and built to provide trouble-free perform-
ance, 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 500 Integrated amplifier 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 amplifier, for example, flower
vases 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 amplifier is dangerous, and may cause electric shock or fire hazard.

Do not place the unit near heat sources such as radiators, direct sunlight or other equipment.
The case of this amplifier can run at high temperatures - operate the unit in a well ventilated
area, and do not touch the cabinet sides or top after periods of use at high output power.

Do not remove covers or try to gain access to the inside.  There are no internal user adjust-
ments 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 claims.

Dust regularly with a soft duster 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 500 Integrated 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 interfer-
ence.  However, if a problem persists, please contact your Musical Fidelity agent.
