Warranty conditions 

 

LaserBit

  Communications Corp. warrants that the 

LaserBit

 product purchased 

will free from defects in material and workmanship for a period of one (1) year from 

the date of purchase. This warranty period will not be extended by virtue of a repair 
of the product or a replacement of any component of the product during the 

warranty period. This warranty covers only normal commercial use. 

LaserBit

 

Communications Corp. is not responsible for warranty service should the 

LaserBit

 identification marks, serial numbers or original seals be removed, altered, 

or broken, or should the product fail to be properly maintained or fail to function 
properly as a result of any modification, misuse, abuse, improper installation, 

neglect, improper shipping, damage caused by disasters such as fire, flood, 
earthquake or lightning, improper electrical current, or service other than by 

LaserBit

 Communications Corp. or its authorized partners. 

 
If the 

LaserBit

 product fails to operate as warranted at any time during the 

warranty period, 

LaserBit

  Communications Corp. will repair, or at its option, 

replace the defective product at no additional charge.  

 

In no event will 

LaserBit

  Communications Corp. be liable for any damages 

including loss of data, lost profits, lost savings, lost business, or other incidental or 

consequential or indirect damages arising out of the installation, use, maintenance, 
performance, failure or interruption of the 

LaserBit

 product, even if 

LaserBit

 

Communications Corp. has been advised of the possibility of such damage. If you 

purchased the 

LaserBit

 product in the United States, some states do not allow the 

limitation or exclusion of liability for incidental or consequential damages, so the 

above limitation may not apply to you. 
 

The purchaser or user shall have the responsibility to give 

LaserBit

 

Communications Corp. prompt written notice of any warranty claims. If the 
product was purchased through an authorized partner of 

LaserBit

 

Communications Corp., notice may be given in writing to that authorized partner 
in the area in which the product was being used. The product may be returned to 

LaserBit

  Communications Corp. only if it has a Return Material Authorization 

(RMA) number. The product must be shipped prepaid, insured and in the original 
shipping package or similar package for safe shipment. The RMA number must be 

marked on the outside of the shipping package. Any product returned without an 
RMA number shall be rejected. 

 

Transportation charges for the return of the product will be paid by 

LaserBit

 

Communications Corp. if it is determined by 

LaserBit

 Communications Corp. 

that the product was defective within the terms of the warranty; otherwise the 
purchaser or user shall be responsible for costs of return handling and 

transportation.  
 

If the 

LaserBit

 product does not operate as warranted above, the customer’s sole 

remedy shall be, at 

LaserBit

  Communications Corp.’s option, repair or
