English to Spanish Law/Patents Medical: Instruments legal foreword

Hi there,

This is part of a legal foreword within an instruction manual for a medical device.

"Upon request, xxxx may provide, with compensation, necessary circuit diagrams, calibration illustration list and other information to help qualified technician to maintain and repair some parts, which xxxx may define as user serviceable."

I'm not sure what the Spanish equivalent would be and how the whole sentence would read. Any help would be very much appreciated!

Thanks
