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 out the intercon-
necting cords and then go through the TROUBLE SHOOTING section in the 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 con-
nection, 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 read-
justment.  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

You will save yourself time and trouble if you will follow the steps below:

A. DO NOT return equipment to the factory for repair without first contacting us by letter 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 am to 4 pm (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 damage
to equipment that you ship.  Of course,  we insure the equipment when we ship it back to you.
