 To set up active wear, first remove the battery pack from the control unit. Make sure that the battery pack cover lock is in the vertical unlocked position. If it is in the horizontal locked position, use the plastic screwdriver to unlock the cover. Then slide it completely off the battery. To remove the rechargeable battery, press the tip of the release lever on the battery and gently detach it from the control unit. To attach the active wear cable, insert the hook on the control unit into the matching groove on the active wear connector and push the parts together until the release lever engages. Slide the cover over the active wear connector and lock it in place. Attach the rechargeable battery to the other end of the cable by inserting the hook on the cable connector into the matching groove on the battery. Push together until the release lever engages. Check that the battery pack cover is in the unlocked position. Then slide it over the battery pack and lock it into position. Connect the attachment clip by sliding the silicone ring of the clip over the battery pack. On the cable connector, there is a raised circular tab with the metal logo. Slide the small hole on the bottom of the attachment clip over this tab to keep it firmly in place. Now the battery pack can be clipped to clothing.
