Service and Repair

If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment 

needs repair.  Make sure you have followed the setup procedure and operating instructions.  Check the interconnect-

ing cables and then go through the 

Troubleshooting section in this manual.

We strongly recommend that you 

do not try to repair the equipment yourself and do not have the local repair shop 

attempt anything other than the simplest repair.  If the repair is more complicated than a broken wire or loose connec-

tion, send the unit to the factory for repair and service.  Don’t attempt to adjust any controls inside the units.  Once 

set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment.  

There are no adjustments inside that will make a malfunctioning unit start working.

LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment.  In warranty repairs 

are made at no charge in accordance with the terms of the warranty.  Out-of-warranty repairs are charged at a modest 

flat rate plus parts and shipping.  Since it takes almost as much time and effort to determine what is wrong as it does 

to make the repair, there is a charge for an exact quotation.  We will be happy to quote approximate charges by phone 

for out-of-warranty repairs.

Returning Units for Repair

For timely service, please follow the steps below:
A.

  DO NOT return equipment to the factory for repair without first contacting us by email or by phone.  We need 

to know the nature of the problem, the model number and the serial number of the equipment.  We also need a 

phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).

B.

  After receiving your request, we will issue you a return authorization number (R.A.).  This number will help speed 

your repair through our receiving and repair departments.  The return authorization number must be clearly shown 

on the 

outside of the shipping container.

C.  Pack the equipment carefully and ship to us, shipping costs prepaid.  If necessary, we can provide you with the 

proper packing materials.  UPS is usually the best way to ship the units.  Heavy units should be “double-boxed” for 

safe transport.

D.

  We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam

-

age to equipment that you ship.  Of course,  we insure the equipment when we ship it back to you.
