Why is my ARTEX C406-2 Transmitter showing a 1-Flash error?
- J
  Jeffrey McdanielAug 9, 2025
  A 1-Flash error on your ARTEX Transmitter can be due to several reasons related to the G-switch loop or remote switch harness. Here's what you should check: * Check the remote switch harness connector at the ELT for looseness or disconnection and tighten if necessary. * Inspect the ELT connector pins for bending or breakage, and repair or replace as needed. * Look for an open jumper (internal to the remote switch harness connector at the ELT end) on connector pins 5 and 8, and repair the open jumper.

  If your ARTEX Transmitter ELT won't turn off, here are some possible causes and solutions: * The battery may be too low to support a 406 burst, causing the circuit to reset. Remove the battery pack to disable the ELT and then replace the battery pack. * Check the wiring continuity of the remote switch harness reset circuit and repair as necessary. * The remote switch might be defective, consider replacing it.

What to do if my ARTEX Transmitter is showing a 5-Flash error?
- J
  Jennifer SilvaAug 18, 2025
  A 5-Flash error on your ARTEX Transmitter indicates that no navigation position data is present. To resolve this: * Ensure the aircraft navigation system is turned on. * Check the system interface wiring and connections for continuity and security. * If a 453-6500 ELT/NAV Interface is required but not installed, install it. * Reprogram to short message.

How to fix ARTEX Transmitter remote switch LED always on?
- B
  Brett MoralesAug 29, 2025
  If the remote switch LED on your ARTEX Transmitter is always on (steady), it could be due to improper wiring or a short circuit. Verify the wiring, check for frayed insulation, and verify the integrity of all crimp and solder connections.

  A 3-Flash error on your ARTEX Transmitter indicates a potential 406 MHz transmission problem. Here's what you can do: * Verify the coax cable/antenna is connected and in good condition. Perform a continuity check of the center conductor and shield, and check for a shorted cable. * Check for intermittent connections in the coax cable. * Use a VSWR meter to check the antenna. Look for opens, shorts, or a resistive ground plane connection. * Adjust the antenna coax cable length by 4 to 6 inches to address impedance issues. * Ensure a ground plane of at least 12 inches in diameter is present. * Keep the antenna at least 10-12 inches away from upright metal structures to prevent re-radiation. * Check if the battery is low. * Verify the 406 MHz programming. If these steps don't...
