LOW BATTERY
In a low battery condition, the SEMS II distress alarm will produce a single
audible chirp from the sensor module once every two (2) seconds and the
green light on the control module will not ash.
While in low battery condition, the SEMS II distress alarm will continue to
operate for a period of time greater then the longest duration cylinder avail-
able for the respirator. However, the batteries must be replaced before the
respirator is used again. See the BATTERY REPLACEMENT section of these
instructions.
If batteries are completely discharged or have not been installed, there will
be no light or sound and the unit will not operate.
