- Page 8 V. Cautions When Removing or Attaching the Shield Cover 1. When handling with the shield cover, do not damage the components on the TX-RX unit. 2. When installing the shield cover, insert the cover from the rear side. 3. When removing the shield cover, squeeze the hole marked with an arrow as shown in the diagram and pull it straight up.
