Vagal Boost instructions

Everything you need to get started with your tENS Vagal Boost: the full instruction booklet, and the three things that catch most people out.

Download the instructions (PDF)

32 pages, 1 MB. Includes safety information in 26 languages.

Three things to know

  1. Press and hold M for about two seconds to switch on. A quick tap does nothing.
  2. Press + to at least level 1. Boost wakes at level 0, and if you leave it there it switches itself off after thirty seconds.
  3. Changing mode resets the level to zero. Press + again every time you change mode.

Your first session

Put a thin layer of the comfort paste from the box (or a drop of water) on both pads. Clip onto the tragus, the small flap at the front of your ear. Plug Boost into your phone, laptop or a USB power bank. Hold M until the display lights up, short-press M until it shows C, the gentlest mode, then press + to level 1. Fifteen minutes is a session. Boost won't stop on its own: hold M to finish.

Samsung phones don't power the Boost. Use a laptop USB-C port or a USB power bank instead. Never use a mains wall charger.
