Quick help
- Broadcast sends a message: as a flashing light in Morse code (far away, line of sight), or as a screen code (up close).
- Scan reads one. Point the camera at the light or code. Tap the blinking light to lock on. The Auto control sets sensitivity for you.
- Talk is a two-way conversation over light between two phones: one calls, the other answers.
- Hold the phone steady, and set the two phones to the same speed if a message won't read. Slower is easier to read.
- No second phone? Try the web reader or the Morse game.
Safety
- The app flashes a light rapidly. Don't use it if flashing lights can trigger seizures or migraines for you or anyone nearby.
- Signal Beacon is an aid, not a substitute for emergency services. If you can, call your local emergency number.
