You can see how to change attachments including a properly installed keyring attachment in this video.
- Turn over the attachment so the small square notch in the center of the cylindrical insert section faces inward toward the Tag and one end of the attachment's cylinder lines up with either side of the Tag's attachment tube. For the clip attachment, this is the only way it can be inserted.
- Press firmly near the insert section to slide the attachment into place. You should feel the attachment settle in place when it is centered through the Tag's attachment slot and the tab in the slot pops into the notch in the attachment
- Press firmly on the attachment near the Tag's attachment tube and slide it fully out in either direction.
The keyring attachment should be installed as shown on the right to make sure it is firmly in place in the Wearsafe Tag. Improperly installed attachments do not engage the attachment lock and may slip out of the Tag during normal use.
