Battery Replacement (Fig. 10)
The “low battery” indicator flashes repeatedly when the battery should be replaced. The welding filter must be
removed before battery replacement can be carried out. Take out the battery holder (a small screwdriver can be
used if necessary). Remove the used batteries and dispose of them according to the local regulations. Insert two
new CR-2032 batteries in the battery holder. (Fig. 10) Push the battery holder into the welding filter until it snaps
in position.

INSPECTION
Carefully inspect welding filters before each use. Cracked, pitted or scratched filter glass or protection plates can
seriously impair protection and reduce vision. The sensors on the ADF must be kept clean and uncovered at all
times to provide correct function. Check for cracks in the shield and look for light leaks. All damaged
components should be replaced immediately.
• Before each use, perform the inspection described in these User Instructions to ensure that all
components are installed and functioning as intended. Use of 3M™ welding shield assemblies that
do not meet these inspection requirements may result in permanent eye injury and vision loss.
• Do not use welding filters that are cracked, pitted or otherwise damaged as these conditions may
compromise eye/face impact protection and may allow harmful UV and IR radiation to pass through
causing permanent eye injury and vision loss.
