Controller Maintenance for your COBRA 18R and 18R2

While not required to maintain your limited-lifetime warranty 18R2,  here are a few recommended maintenance tips for your COBRA controller.

  • Remove batteries, and inspect contacts to ensure no corrosion or visual damage.
  • Confirm battery contacts are bowed out at a similar distance and that the batteries snap in tightly.
  • Check all buttons to confirm none are sticking and that they bounce back after they are released.
  • Check all LEDs and 7-segment displays. Note that if an LED or 7-segment display bar is not functioning, the unit will still operate normally.
  • Check the antenna connector and confirm there is no corrosion or damage. Ensure the antenna screws on smoothly, and the antenna connector does not rotate freely.
  • For the 18R2, confirm the USB connector and other connectors such as SMTPE or Deadman are not damaged, corroded, or have any physical issues.
  • Confirm the battery door snaps on and off correctly.
  • Store in a dry, room temperature environment.
  • Confirm signal strength, at ~30m, raised up ~1m, you should see between -35 and -45dB on average.
