In tune before the count-in.
Tuning should take a few seconds and none of your focus. Clip it on, play a string, and the detected note name appears on the secondary display. The display flips automatically, so it stays oriented for viewing at all times.
Two ways to read one string
Needle mode shows pitch as a column of five LEDs: left is flat, right is sharp. Strobe mode adds rotating segments, and you tune until they slow down and stop. Chromatic tuning mode is accurate to ±0.5 cent, strobe tuning mode to ±0.02 cent.
Match the pitch everyone else plays at
The default reference is A = 440 Hz. Press REFERENCE TONE to raise it, or DISPLAY MODE to lower it, in 1 Hz steps. The range runs from A4 = 435 to 445 Hz. Leave both buttons alone for 2 seconds and the setting is stored.
Small enough to stay on
