GENERAL ADVICE

INSTALLATION  PRECAUTIONS  and  USER  INFORMATION

Your A308 Integrated amplifier 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 A308 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 in a well ventilated area, and
do not touch the side heatsink fins 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.  Refer all service work to an authorised Musical Fidelity agent.

NOTE: Unauthorised opening of the equipment will invalidate any warranty claims.

There are fuses inside the A308 Integrated amplifier.  In the unlikely event that one blows, refer
the unit to your audio dealer.  Do NOT try to replace the fuse yourself as this will invalidate the
warranty.

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 A308 Integrated 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.
