The blue lights indicate the selected fan speed. The red lights indicate the level of blockage.
When the lights flash red and blue, the selected fan speed cannot be reached, but sufficient air
supply (170slpm) can still be reached. When 3 lights flash red, the alarm will sound indicating
insufficient air supply is being produced. Return to a safe environment and check the filter and/or
the airway for blockage. If the filter is contaminated, replace with a new cartridge.
When the alarm sounds it is recommended that you leave the work area immediately. Do not
remove the respirator, remove the filter, or disconnect the breathing tube while in the work
area. Once outside of the work area power the unit down and resolve the problem.
