| | [* icon_reminder] Before installing the new diode, use a multimeter or ohmmeter to verify that it is functioning correctly. A working TVS diode will exhibit significantly higher resistance in one direction than the other. |

| | [* black] To install the new diode: |
|---|
| | [* icon_caution] Check the orientation marking on the diode to ensure it is positioned correctly, with ***the bar pointing toward the antenna***. |
|---|
| | [* black] Apply flux to the pads and add a thin layer of solder. If solder does not adhere to the pads, you can add it to the underside of the diode pins instead. |
|---|
| | [* black] Hold the new diode in place using tweezers. While applying downward force, apply heat to one pin near the solder until the solder melts and makes a connection. Repeat with the other lead. |
|---|
| | [* light_blue] Verify that the connections are good. There should be continuity between one pin of D6 and a pin in VR3, and between the other pin of D6 and D7. |
