3.Remove used battery from battery compartment by lifting bottom of battery, using a finger or the flat blade of a screw driver, being careful not to damage battery contacts or sealing rib around bat- tery compartment.

Use only one of the following: Eveready Alkaline No. 522 or EN22, Duracell Alkaline No. PC1604 or MN1604, or for increased service life use Ultralife Lithium Battery No. U9VL. Be sure battery is installed with the terminals positioned as indicated by symbols on label in bottom of battery compartment.

Check cover seal for tears or cuts. If damage is found, remove respirator from service and tag for re- pair by authorized personnel.
