Repair (RMA)

DEIF guidance to customers regarding product returns

DEIF is an ISO 9001 certified company maintaining the strictest product quality and with the ultimate goal of achieving a zero fault level. However, should a product nevertheless fail we will repair or replace the product in accordance with our standard terms and conditions.

This is to guide you through our product return process.

Is the product defective?

A number of returned products turn out not to be defective with their malfunctioning being attributable to other causes, such as wrong installation or signal failure caused by other components of the installation environment.  In order to avoid such inconveniences please check the installation carefully before you decide to return the product. Returned products undergo a careful examination at our factory and you may be charged for this effort in case of no faults found in accordance with our standard rates. If in doubt please contact our service department at or +45 9614 9614.

Can the problem be cured on site?

For products with embedded software the problem may be curable by downloading alternative or updated software versions. Please check our download centre site whether there are such options available. If in doubt, please contact

Is returning a product cost effective?

Before deciding for a return we encourage that you check the cost efficiency of the returning rather than ordering a new product. Depending on the new product and the old product return cost it may be more affordable to purchase a new product.
