Step 6
Separating the front bezel from the panel assembly

- You should be able to remove the front bezel easily to work on it. Some button caps might actually fall off of it if they are broken.

Step 7
Preparing the front panel button cover fix
- Remove all broken button caps. You might want to completely break those with a partially broken stem using an sharp blade.
- Clean the button caps, and the parts which will have to be glued back using isopropyl alcohol.
- Find something to put under the front bezel so the buttons caps won’t be pressed back up when gluing them.
- Cut 5 pieces from a light cardboard box, 5mm x 15mm, and fold them in a U shape. These will help holding the button caps and keep them centered in place.
- Cut a dozen pieces about 1mm x 4mm from a pill blister or some other PVC blister. These will be used to reinforce the part we glue back.

Step 8
Gluing back the front panel button caps
- Put some acetone based glue (like UHU Plast), one drop on each broken stem.
- Place one of the U-shaped cardboard piece in the button cap hole, and push the cap inside until it is correctly held in place.
- Make sure each stem is correctly back in place both horizontally and vertically.
- Repeat for each button cap.
- Let the glue dry (up to 24 hours).

Step 9
Reinforcing the button caps
- Place a drop of the same glue over each place that was glued back, and put one of the blister pieces we cut. If you used the aluminum coated part of the blister, make sure the aluminum is on the outside, not facing the glue.
- You may need to also do this on the other end of the stems for some buttons if you notice they show sign of wear.
- Repeat for each button cap.
- Let it dry (up to 24 hours).
- Put it all back in reverse order.

To reassemble your device, follow these instructions in reverse order.
If one of the two back panel screw covers doesn’t fit flush, remove it, loosen the screw and re-tighten it while holding the back cover in alignment with the front bezel so the screw is centered, and retry putting the cover back.
