Choose how signals reach you (sound, lamp or both), set the CW tone, speed, Farnsworth spacing and key bindings, and export or import your progress.
Signal
How every Morse signal on the site reaches you: as a tone, as a light, or both.
Sound plays the tone. Lamp flashes a light with the same timing and stays silent. Both does both. Listening practice works in every mode.
The pitch of the sidetone, in hertz. Pick whatever sits most clearly against your own hearing. Now 600 Hz.
Sends VVV, the operator's traditional test signal, at your tone, volume and speed.
On an iPhone, the ring/silent switch on the side also mutes sound from web pages. If the test signal is silent, check that switch first.
Timing
How fast Morse is played to you. Character speed shapes each letter; effective speed sets the space around it.
How fast the dots and dashes themselves are sent. Keep this high, even as a beginner.
Farnsworth spacing. Below the character speed, it stretches the gaps between letters, which is what stops you learning to count beeps.

PARIS is the standard word that words-per-minute is measured with.
Key
How your keying is read on the telegraph, in lessons and in practice.
A straight key: you time every dot and dash yourself. The way the course teaches.
On the straight key, hold longer than this and it sends a dash. For reference, at 15 WPM a dot lasts 80 ms and a dash 240 ms.
How long you may pause mid-character before it counts as finished. This is thinking time, not speed.
Select a key, then press the one you want. Escape keeps the old one.
Teaching order
Which order new characters arrive in. The practice screen has the same choice; this is the place to set it once.
Follows the structure of the code itself: E and T, then every two-element character, then every three. You finish each stage having completed a whole layer of the Morse tree, which is why the tree lights up in rings rather than at random. Best if you want the alphabet to make sense rather than just be memorised.
2 characters. More arrive when a practice session long enough to count scores 90% or better.
E T
Display & motion
Dark is the station at night; light is the telegram form. The same switch sits in the header.
Following the system is usually right. The overrides exist because the system setting is all or nothing.
