Jensen needed to reduce product returns on their radios due to poor installation from do-it-yourselfers to retail technicians.
Explainers accommodated a range of end-user competence and experience levels by creating a visual installation guide.
Technicians could glance at the wiring diagram to verify proper installations.
Do-it-yourselfers could use the product illustrations as well as the step-by-step instructions to make all the connections.
This approach reduced product returns and improved relations with retail dealers.
