Fuses

The SE-240 is supplied with a 10 ampere Slo-Blo AC line
fuse and four power supply fuses. If one of these fails, it

is usually indicative of a fault which will require professional
service.

The Hafler SE-240 is warranted for 3 years from date of

Units under warranty should be accompanied by a copy of

the dated bill of sale. Use the original carton and all

packing material, and be sure to include a return address.
Also give a brief description of the difficulty, including
whether it is intermittent.

Warranties apply only to the original purchaser, and are
void if the amplifier has been modified without factory

the factory’s opinion, are not suitable, or if the amplifier has

been physically or electrically abused or used for some
purpose for which it was not designed or intended.

This warranty gives you specific legal rights. You may also

have other rights which vary from state to state.
