Early CTRL.3 units were shipped out with a poorly designed battery latch that makes it difficult to open the battery door, especially if no battery is installed.
To remedy this, we have redesigned the battery latch and will replace it free of charge for any customers with the original latch. This can be done one of two ways:
* Replace it yourself. Contact firstname.lastname@example.org with proof of purchase and a shipping address, and we will mail you a kit with a new battery door assembly and all of the parts and tools required to replace the door. The process involves removing only one screw and one small dowel pin. Find detailed instructions below.
* Return CTRL.3 to us and we will replace the battery door. Contact email@example.com to start the return process. The door replacement is simple, but expect it to take up to 7 days for receiving, processing, fixing, and returning your device, in addition to any additional time for shipment to Irvine, California. We are happy to do this but would encourage most users to opt for self-replacement of the door.
- Remove the screw on the side of CTRL.3 using the included hex key.
- Remove the battery door and dowel pin.
- Insert the dowel pin into the hole on the right side of the new battery door.
- Open the threadlocker (Loctite)
- Apply a small amount of Loctite to the tip of the screw. NOTE: Only a small amount of Loctite is required, do not apply Loctite to the full length of the screw.
- Locate the dowel pin hole on the CTRL.3 chassis.
- Insert the new door with dowel pin into the chassis and align the chassis and door screw holes.
- Insert the screw through the chassis and into the battery door. Tighten completely to seat the screw, chassis, and battery door.
- Rotate the screw counter-clockwise (unscrew) approximately 90 degrees (1/4 turn) to set the tension of the battery door.
- Open the battery door and check the tension. It should rotate freely, but not feel too loose.
