Guide: 5. Technical
5.1. Installation

TraqFreq in its case holder in a smaller than 0-size guitar


  1. TraqFreq is supplied with a case holder (see photograph above) that is to be used mainly when installing inside an instrument. This will enable one to remove it entirely and single-handedly with the utmost of ease when changing the battery.

  2. Only mount the TraqFreq without the case holder when it is in plain sight, such as behind the headstock of an electric guitar and on a saxophone.

  3. Mounting without the case holder ensures that the device will not move or be dislodged ordinarily when it is touched.

  4. For optimum play detection, mount the TraqFreq securely on the surface with the supplied adhesive tape.

  5. The ideal transmission range can be obtained by mounting the TraqFreq with the logo facing away from the instrument (see photograph below), as this is where the antenna is housed.

  • Violins & Violas
    Mount on a bracket directly without the case holder and attach as desired. These optional brackets are available for purchase in our store.


  • All Woodwinds
    To begin with, the instrument needs to be large enough to house the TraqFreq - for example, the clarinet and oboe. For these types of woodwinds, mount where space allows and without the case holder.

5.2. Calibration

TraqFreq requires calibration after installation and every time it is repositioned or removed. Calibration is necessary for proper optimization, and the procedure differs according to the instrument. The process is always simple and fast, and it is not required if the TraqFreq is not relocated in between replacing the battery. When that does occur, TraqFreq will alert you to the fact.
