April Music Stello DA100 - Manual (Page 13)

WARRANTY
April Music, Inc. supports 2 years of free warranty for DA100 under normal
use from the date of delivery.
This warranty extends only to the original purchaser and does not apply to the
parts that have been subjected to misuse, or abnormal operations. If the second
hand user wants to inherit the warranty period, he (she) should contact April
Music, Inc, by send an e-mail or a letter to activate the remaining warranty.
In the event of failure during the warranty period, April Music, Inc. will repair
the DA100 at no charge as long as the unit is not working under normal use.
If the unit is damaged by the abnormal use (incorrect voltage connection,
spilling coffee over the top etc.) and if you or your dealer can not fix the
problems, the unit should be returned to the factory.
In this case, the estimate repair fee (including shipping & handling) will be
submitted before the repair for shipping.
A return authorization is required when sending the units for repair. They must
be shipped to April Music, Inc, prepaid and with its original cartoon (preferred).
There are no user serviceable parts inside except the voltage changing. And
DA100 is running very hot inside because all analog outputs are full class-A
operated discrete circuit. Care should be taken.
If you or any unauthorized persons have tried to change or modify the circuits
without any prior consent from April Music, Inc, all the warranty will be void
even the units are under warranty period.
* Do not try to modify the products by any unauthorized persons!
