Notes and Tips
A few radios use different 4‑pin wiring. If your radio doesn’t key up or audio is missing, verify the pinout in your manual.
Some Midland, President (older), and specialty/export models may require rewiring to match the Cobra/Uniden standard.
For best results, keep the mic 1–2 inches from your mouth and speak across the mic at a slight angle.
