1. Start-up
a) Use of the SEMS Portable Unit begins when the user opens
the cylinder valve on the respirator to start respirator usage.
The unit will sound three chirps to indicate activation.
b) After a brief start-up sequence of less than ten seconds, the
green light in the Portable Unit display will flash to indicate
operation of the Portable Unit. An alert tone, a “BE-doop” to
indicate the system activity, is used for several functions. When-
ever the alert tone occurs, the user should look at the Portable
Unit display for information.

GREEN LIGHT IS NOT FLASHING NORMALLY,

OF A MALFUNCTION WITHOUT THE USER TAK-
ING PROPER CORRECTIVE ACTION, EMS MAY
LEAD TO CIRCUMSTANCES THAT RESULT IN
