  • Page 9: Operation

    Once a proper level is achieved no further adjustment should be necessary. THEORY OF OPERATION The 8895-AMP-8 & 8895-AMP-16 are built in two configurations, an 8-patient and a 16- patient version. There are eight output audio amplifiers in the -8 and sixteen in the -16, each driving one patient entertainment module.
  • Page 10 MODEL 8895 USER MANUAL The entertainment module contains an audio transducer which produces an audio sound pressure wave to drive a pneumatic headset. The entertainment module has a diaphragm to separate the transducer from the sound tube. This prevents the possibility of the back flow of oxygen into the transducer when the headset is being used in an oxygen enriched area such as an oxygen treatment hood.
