CARVIN HT150 Operating Manual

This symbol is intended to
alert the user to the pres-
ence of uninsulated "dan-
gerous voltage" within the
product's enclosure that may be of suf-
ficient magnitude to constitute a risk of
electric shock to persons.
IMPORTANT! FOR YOUR PROTECTION, PLEASE READ THE FOLLOWING:
WATER AND MOISTURE: Appliance should not be used near water (near a bathtub, washbowl,
kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc). Care should be taken
so that objects do not fall and liquids are not spilled into the enclosure through openings.
POWER SOURCES: The product should be connected to a power supply only of the type described
in the operating instructions or as marked on the appliance.
GROUNDING OR POLARIZATION: Precautions should be taken so that the grounding or polar-
ization is not defeated.
POWER CORD PROTECTION: Power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against them, paying particular attention
to cords at plugs, convenience receptacles, and the point where they exit from the appliance.
SERVICING: The user should not attempt to service the appliance beyond that described in the
operating instructions. All other servicing should be referred to qualified service personnel.
FUSING: If your unit is equipped with a fuse receptacle, replace only with the same type fuse.
Refer to replacement text on the unit for correct fuse type.
SAFETY INSTRUCTIONS (EUROPEAN)
The conductors in the AC power cord are colored in accordance with the following code.
GREEN & YELLOW—Earth
U.K. MAIN PLUG WARNING: A molded main plug that has been cut off from the cord is
unsafe. NEVER UNDER ANY CIRCUMSTANCES SHOULD YOU INSERT A DAMAGED
OR CUT MAIN PLUG INTO A POWER SOCKET.

LIMITED WARRANTY
Your Carvin product is guaranteed against failure for ONE YEAR. Carvin will service and supply all
parts at no charge to the customer providing the unit is under warranty. Shipping costs are the respon-
sibility of the customer. CARVIN DOES NOT PAY FOR PARTS OR SERVICING OTHER THAN OUR

not cover, and no liability is assumed, for damage due to: natural disasters, accidents, abuse, loss
of parts, lack of reasonable care, incorrect use, or failure to follow instructions. This warranty is in
lieu of all other warranties, expressed or implied. No representative or person is authorized to rep-
resent or assume for Carvin any liability in connection with the sale or servicing of Carvin products.
CARVIN SHALL NOT BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES.

FLAT RATE for parts and labor to bring your unit up to factory specifications.

HELP SECTION

1) WILL NOT TURN ON

Check the power to the unit. Check for tripped circuit breakers, unplugged extension cords or
power-strip switches that may be turned off. Check the fuse. If a dark brownish color or no wire
can be seen within the glass fuse, then replace. The unit may be perfectly fine but occasionally
the fuse may blow because of high AC voltage surges. After the fuse has been replaced with the
proper value and if the fuse fails again, the product will require servicing (be sure to use a slow
blow fuse if required). Check your input and speaker output cables.

2) MAINTAINING YOUR EQUIPMENT

Avoid spilling liquids or allowing any other foreign matter inside the unit. The panel of your unit can
be wiped from time to time with a dry or slightly damp cloth in order to remove dust and bring back
the new look. As with all pro gear, avoid prolonged use in caustic environments (salt air). When
used in such an environment, be sure the amplifier is adequately protected by rack, covers, etc..
