Heterodyne Feature - TRACER PRODUCTS MARKSMAN II TP-9367L Guide De L'utilisateur

HETERODYNE FEATURE

The Marksman II features heterodyne capability, which converts
the ultrasonic frequencies detected by the instrument to sounds
that can be heard by the human ear. This allows you to more
easily isolate the ultrasonic source.
Simply plug the included headphones into the jack on the right side
of the Marksman II to enable heterodyne capability. Dragging your
finger upwards/downwards on the sensitivity touch pad will increase/
decrease the volume of the headphones.
