Your COBRA 18R2 controller is for the most part, maintenance-free, but there are a few things that can be done before putting away your firing controller for the season.

Here are a few maintenance recommendations for your COBRA 18R2 controller.

● Remove batteries, inspect contacts to ensure no corrosion or visual damage.

● Check all buttons to confirm none are sticking and that they bounce back after release.

● Check all LED indicators and 7-segment displays. 

    Note: If an LED or 7-segment display bar is not functioning, the 18R2 will still run 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.

● 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 ~1m, you should see between -35 and -45dB on average.

If you discover any issues during the maintenance inspection, please reach out to COBRA support at or via the phone at 518-741-4300.
