below the minimum requirement of 6cfm (170slpm) for more
than 5-10 seconds in duration.
Leave the work area to check the filter for blockage or
anything obstructing the air path to the head-top. If the filter
is blocked due to contaminants, replace the filter with a new
one.

if the battery is overheating. If the unit is operated outside
this temperature range for 10 minutes the battery alarm will
activate.
