The box is equipped with a system of analog pressure converters 0-5V and built-in gas monitor. Too
high or too low level or excessive gas consumption is signaled optically and acoustically (break-down
consisting in damage of the distribution conduits or the medical equipment).
1.1 Information about the device
Device should be stored in a dry place in temperature b10 C - +45 C.
