Discovery 640/645: How to Disconnect the Components
How do I disconnect the components of the Discovery 640/645?
The battery charger and the charging adapter can be connected to the headset's carrying pocket by pushing the two components together. (Be sure that the indent of the attachment lines up with the shirt clip on the carrying pocket.) To separate the components, grasp both the carrying pocket and the attachment with the shirt clip facing you. Apply pressure while bending them, and the components will snap apart.
