The voice recorder is a standard dictaphone modified to record the passage of LF through the pressure of a push button. The button is pressed by the astronaut when he perceives a LF. This signal is recorded on cassette together with voice description of the type of LF. Time and date of start of operations must be also recorded by the astronaut on the experiment logbook. Photos of relative position of the astronaut with the LAZIO-MEB and the ALTEINO detectors is taken (the astronaut need to be strapped during LF observation). The astronaut wears light shielding mask during LF observation sessions. Cassettes are replaced every session.
