Troubleshooting - Antennas
If the display frame plated area is cracked or the metal plating is peeled off, then the
grounding of the display shield and frame will not be guaranteed. Replace the frame.

Display assemblies of RH-34 (6585) and RH-27 (6225) are very similar. However, the
RH-27 display shield is different on the side from the RH-34 shield, as shown in Figure 9
inside the blue dashed line. Second, the metal plating at the top area of the RH-27 frame
is different from the top of the RH-34 frame, as shown in Figure 9 inside the blue dashed
line. For RH-34 frame, the screw boss area is plated but isolated from the rest of the
frame, and also there is no plating in the area inside the green dashed line in Figure 9.
