Wax guard (CeruSTOP) A wax guard, also called CeruSTOP at Widex, is a protective filter that prevents ear wax from working its way into the precision in-the-ear hearing aid.

Change a CeruSTOP wax guard as follows:

With the holder perpendicular to the face of the bushing, insert the removal hook into the used wax guard so that the shaft of the holder is touching the rim of the wax guard, then slowly pull the wax guard straight out.

Now turn the holder around so that the used wax guard is away from the instrument and the new one is in position to be inserted into your hearing aid.

Gently press the new wax guard straight into the opening of the sound outlet. Do not force the wax guard into the sound outlet. The outer rim of the wax guard should sit flat on the stainless steel bushing.

Then pull the holder straight out. Do not twist the tool. The new wax guard will automatically dismount from the holder and remain in place.

After inserting the new wax guard, discard the holder with the used wax guard attached to the removal hook. Never reuse a wax guard.
