Repair Service

All warranty repairs are performed at no cost. Positron reserves the right to repair 
or replace any equipment that has been found to be defective.

For information about out-of-warranty repairs, contact Positron’s Repair 
Department. Due to the varied nature of repairs, no specific turnaround can be 
guaranteed, but average turnaround time is 20 working days from date of receipt. 
In emergency situations, special arrangements can be made. All repaired items 
are warranted for a period of 90 days.

Before returning any items to Positron for repair, warranty repair or replacement, 
call the Repair department to obtain a Return Material Authorization (RMA) 
number. Parts returned without RMA numbers cannot be accepted. The RMA 
number must always be clearly marked on all boxes, crates, and shipping 
documents. Bulk repairs (more than five items) will require additional processing 
time, so please take this into consideration when requesting an RMA number.

To accelerate the repair process, whenever possible, include a report detailing the 
reason for return with the unit(s). Also, please include the name and phone 
number of a person who can be contacted should our Repair department need 
further information.

When packing items being returned for repair, please ensure they are properly 
packed to avoid further damage. TeleLite plug-in cards should never be shipped 
while installed in a shelf; this will cause damage that can extend the repair period.
