Soundscape: Paranal attention UT3 operator

This audio (in Spanish) is a radio communication from inside the telescope (UT3) between the Telescope Start-up (the engineer in charge of the telescope’s start-up) and the Telescope and Instrument Operator in the Control Room (CT), announcing that staff is leaving the telescope. No one can enter a telescope without prior authorization by a telescope responsible, and when leaving, a notice also needs to be given. During observations (occurring during night time) the telescope is controlled from CT, located in a separate building, because no one can stay inside the telescope during observations.
