RadioLynx works most of the time but misses some starts. What do I check?
Recover the race with Repeat first. Then check the antennas, cable an electronic gun to the transmitter instead of using a sound sensor, tighten the input cable, run the paperclip test and charge the transmitter.
Press Repeat on the transmitter before the next start: it resends the last start with its original time. Then work through these checks:
- Antennas. Check the right antennas are screwed on fully and that the transmitter's antenna mount doesn't spin.
- Electronic gun: don't use the sound sensor. A sound sensor in front of the gun's speaker is unreliable. Connect the gun to the transmitter with the transmitter input cable instead (for a Gill Halo, Gill's adapter cable), and secure the plug so it can't fall out.
- Transmitter input cable. Slide the black and green covers up the cable and tighten the small screws that hold the wires in the banana plugs. Avoid taping the cable tightly to a tripod.
- Paperclip test. If the transmitter and cable pass but blowing into or tapping the sensor gives no start, replace the start sensor. A sensor that got wet needs a few days to a week to dry; don't take it apart.
- Battery. Three beeps at power-on or after a signal mean the battery is low; recharge it fully before the meet.
- Internal RadioLynx camera. Connect an external receiver to the serial port on the camera back and set Port to Camera Back on the RadioLynx tab. If the misses stop, the internal receiver is the likely cause and the camera and transmitter should go in for repair together.
- Interference. Look for walkie-talkies, wireless TV cameras or other radios near the start or the camera, and try another frequency.

Related questions
- RadioLynx sent the start but FinishLynx never got it. Can I still time the race? — Yes. Press Repeat on the transmitter before the next gun: it resends the last start with its original time, so the race is still timed correctly.
- Why isn't my RadioLynx working properly? — Work through the paperclip test to find which part has failed: the transmitter beeping with the start says whether the sensor and cable are fine, and the test needs only an unfolded paperclip.
- The wind keeps setting off the start sensor before races. Is there a windscreen? — Lynx doesn't sell one: shield the sensor with any object, such as a box or a plastic container. To clear a false start, arm the event (Ctrl+A) and the clock goes back to 0:00.
- The electronic gun flashes but the speaker is silent or too quiet. What do I check? — Too quiet: turn up the speaker's own volume (the Line In knob on the Electronic Start Plus speaker) and check the short aux cable to it. No sound at all: charge the battery and test another audio source.
