In Case of Trouble

Fuses

The HCA-2200II has five external fuses which may blow as a result of an internal fault condition. This
protects the unit from possible damage to internal parts. Never replace any fuse with a larger value. Substi-
tution of a larger fuse may create serious stress or damage to internal parts and will void your warranty.

It is particularly important to replace the 10 ampere B+ and B-  fuses with the same value and brand as the
originals to preserve the impedance symmetry of the power supply. Use only Littlefuse brand fuses.  The
brand of the 15 ampere main fuse is not as critical to sound quality.

If you suspect a problem with this unit, first recheck all your connections.  If one channel is
inoperative, the trouble may be caused by another component or even a defective hookup cable. If only one
channel is out for all sources, try reversing the L and R cables to the power amplifier (turn it off before
moving wires). If the same channel stays out, it indicates trouble with the power amplifier itself. We suggest
you contact your authorized Parasound dealer or call Parasound Technical Service if you suspect a problem.
We will 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-2200II should be returned for inspection and possible servicing, you must
first obtain a Return Authorization number. You will be asked to re-pack the unit in its original styrofoam
packing and both of its cardboard cartons for proper protection in transit. You should send the unit by UPS
with adequate insurance specified.

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