Product Warranty and Return Information 

 

Return Policy

 

 
A.  All returns for warranty, repair, credit or any other reason must be pre-authorized. A return mer-

chandise authorization (RMA) form must be requested from the NITEK Customer Service De-
partment. The form, which will be emailed to the customer, must be filed out completely and 
emailed back to the sender at NITEK for approval. An RMA number will be assigned if the re-
quest is approved. In any event, the customer will be notified by NITEK customer service of the 
outcome. All approved returns must be shipped freight prepaid, insured and properly packaged. 
A copy of the approved RMA form must be enclosed in the shipping container with the goods 
being returned and the RMA number must be marked in a visible area on the exterior of the 
container. 

B. 

Credit Returns must have been purchased within the last 30 days of the date of the receipt        
of the equipment at NITEK. Credit returns must be current  products  listed  on  the  NITEK        
published price list, in effect at the time of the return and must be in new and saleable con-       
dition, with all factory packaging. All Credit returns are subject to a restocking charge of up        
to 40%. Additional restocking and/or refurbishing charges may be assessed upon inspec-     
tion. If it is determined by NITEK that the returned equipment does not meet these condi-      
tions, a credit will not be issued.

 

 
 

Lifetime Limited Warranty 

Video Balun Transceiver Products 

 
NITEK warrants the original consumer purchaser that the Video Balun Transceiver products that it 
sells will be free from defects in material and workmanship. If any such product proves defective 
by our inspection, after sale to the original consumer purchaser, NITEK, at its option, will either 
repair the defective product without charge for parts and labor or will provide a replacement in ex-
change for the defective product. 
 
The purchaser shall be responsible for packaging and shipping the defective product to the ser-
vice location designated by NITEK with shipping charges prepaid. NITEK shall pay for the return 
of the product to the purchaser if the shipment is to a location within the U.S.A. The purchaser 
shall be responsible for paying all shipping charges, duties and taxes if the product is returned 
from a location outside the U.S.A. 
 
This warranty shall not apply to any defect, failure or damage caused by improper use or improper 
or inadequate maintenance or care, or to any product which shall have been repaired or altered 
outside our plant in any way, or which has been operated in a manner exceeding its specifica-
tions, or which has had the serial number removed. NITEK shall not be obligated to furnish service 
under this warranty: a) to repair damage resulting from attempts by personnel other than NITEK 
representatives to repair or service the product; b) to repair damage resulting from improper use 
or connection to incompatible equipment; or c) to service a product that has been modified or inte-
grated with other products when the effect of such modification or integration increases the time or 
difficulty of servicing the product. 
 
This warranty is given by NITEK with respect to the Video Balun Transceiver products in lieu of 
any other warranties, express or implied. NITEK disclaims any implied warranties of merchantabil-
ity or fitness for a particular purpose. NITEK’s responsibility to repair or replace a defective prod-
uct is the sole exclusive remedy provided to the purchaser for breach of this warranty. NITEK will 
not be liable for any indirect, incidental or consequential damages irrespective of whether NITEK 
has advance notice of the possibility of such damages.
