Step 4

              Releasing the midframe

Unsolder the two wires connecting to the loud speaker. (This is not essential but will save you from straining these wires.)
Remove 2 screws from the grey midframe, one on the lower right on the battey connector and the other on the upper left above the tuning knob.
Release the two cables from their retaining clips under the battery compartment.

Step 5

              Removing the midframe

Lift the grey battery connector slightly to disengage a bush where you removed a screw in the previous step. (On reassembly, ensure this is snapped back in place.)
Ease the power and headphone sockets out of their holes in the case, using a spudger or similar tool.
You can now lift the midframe and attached assemblies out of the case, first lifting the right hand side by the power and headphone sockets, and hence withdrawing the volume and tuning spindles from the left hand side.
Before reassembly it’s worth dusting the LCD display and the inside of the display window.

Step 6

              Buttons board removal

Remove two screws holding the buttons board to the midframe.
Lift the buttons board from the power button end, and release the other end from beneath a retaining tab.
On reassembly, ensure that the right hand end of the buttons board is correctly located under the tab, otherwise the assembly will not fit back in the case.
If required, you can now unsolder and replace any of the buttons. For this, a desoldering pump is most effective.
Replacement 6x6mm tactile buttons are widely available in a range of heights. The 5mm height should fit, but lay a ruler along the tops of all the buttons to check the height before soldering a replacement.
