Action

Customer are instructed to: 1. Identify the Non-Tamperproof Battery Door - confirm which door is installed by performing the following check: -When inserted into the battery cartridge, the non-tamperproof door can be removed without using a tool. -The tamperproof battery door requires a tool for removal once installed. If you must use a tool to remove the door, you have the tamperproof door installed. 2. Remove and Dispose of the Non-Tamperproof Battery Door - Once identified, ensure the non-tamperproof battery door is removed from the battery cartridge. Do not reinstall or use this component. 3. Complete the Acknowledgement & Disposal Form (required) - After disposing of the non-tamperproof battery door, confirm that the component has been removed from service and disposed of appropriately by completing the Acknowledgement & Disposal Form linked in your email.
