A monitor system which combines manual and electronic operations is proposed as a method to identify and correct line-call errors which occur in the conventional line-call system used in the game of tennis. The monitor system enables several persons seated in various locations in the stands to act as line-call monitors by identifying obvious or gross line-call errors committed by line judges. The monitors communicate with the chair umpire by means of small hand held "call-box" transmitters each equipped with a push button which is pressed when the monitor detects a clear mistake by the line judge. The chair umpire wears a small radio receiver unit which accumulates the separate or simultaneous decisions of the monitors and generates a short "beep" sound in a speaker or an external earphone if certain simple criteria are met. The umpire can then make the appropriate overrule to correct the line-call error.

Système de surveillance à la fois manuel et électronique permettant de relever et de corriger des erreurs commises par les juges de ligne au tennis, selon les règles traditionnelles applicables. Suivant ce système, plusieurs personnes assises en différents endroits des gradins peuvent jouer le rôle de surveillants en relevant des erreurs évidentes ou grossières commises par les juges de ligne et en communiquant avec l'arbitre de chaise au moyen de petits émetteurs portatifs équipés individuellement d'un bouton-poussoir qu'elles enfoncent lorsqu'elles détectent une erreur évidente du juge de ligne. L'arbitre de chaise porte un petit récepteur radio qui cumule les décisions successives ou simultanées des surveillants et produit un signal sonore dans un haut-parleur ou un écouteur externe si certains critères simples sont respectés. Il peut ensuite prendre les mesures voulues pour corriger les erreurs.
