INSPECTING THE RESPIRATOR
24 P/N 595360-01 Rev G 202004
Testing the Batteries
On respirators equipped with a distress alarm, the battery condition can be tested manually as follows:
1 Make sure the distress alarm is off (i.e., the cylinder valve is closed, and no sensor module lights are flashing).
2 Press and hold the manual reset (yellow) button on the console. Observe the final light color (green or red) in the
sequence to determine the battery status.
• Green lights on the control console and sensor module indicate that sufficient battery power remains.
• Red lights on the control console and sensor module indicate that the batteries are low and must be replaced
before the respirator is used again. 3M recommends replacing all batteries before the respirator is used again.
See “Chapter 4: Replacing Batteries” on page 51.
CAUTION
Do not use tools to close the cylinder valve. Over-tightening the cylinder valve may cause damage that
could result in air leaking from the cylinder.
