Fuse

The HCA-1206 has one external 15 ampere fuse which may blow as a result of an internal fault
condition.  This protects the unit from possible damage to internal parts.  Never replace this fuse with a
larger value.  Substitution of a larger fuse may create serious stress or damage to internal parts and will
void your warranty.

In Case of Trouble

If you suspect a problem with this unit, first recheck all your connections.   If only one channel is
inoperative, the trouble may be caused by another component or even a defective hookup cable.
However, if the same channel is at fault when you reverse the Left and Right channel pair cables to your
HCA-1206 (turn it off before moving wires), it may indicate trouble within the power amplifier itself.
We suggest you contact your authorized Parasound Dealer or Installer, or call Parasound Technical
Service if you suspect a problem.  We may be able to suggest other diagnostic tests you can easily
perform yourself and which will save you a lot of trouble.

If it is determined that the HCA-1206 should be returned to Parasound for inspection and possible
servicing, you must first call or write to obtain a Return Authorization number.  You will also be asked
to repack the unit in its original packing and both of its cardboard cartons for proper protection in transit.

Units that arrive without the correct Return Authorization number, without a suitable shipping carton or
evidence of improper internal packing  will be refused.  We cannot accept collect shipments.  After
repair under warranty, the unit will be returned to you prepaid.  If we found no problem with the unit, we
will return the unit with collect charges for return shipping charges.
