DIGITAL AUDIO LABS LIMITED WARRANTY

Digital Audio Labs warrants their products against defects in material and workmanship for a period of two years

The warranty does NOT cover:

•  Units that have been serviced by unauthorized personnel.

All implied warranties, including warranties on merchantability and fitness, are limited in time to the length of 
this warranty. Some states do not allow time limitations on implied warranties, so this limitation may not apply 
to you. Digital Audio Labs’ liability is limited to the repair or replacement of its product. Digital Audio Labs shall 
in no way be held liable for incidental or consequential damages resulting from the use of their product or 
its software, including, without limitation, damages from loss of business profits, business interruption, loss of 
business information or other pecuniary loss. Some states do not allow the exclusion or limitation of incidental or 
consequential damages, so the above limitation or exclusion may not apply to you.
