Sony M-430 Microcassette-Corder Back Cover Replacement

Find the arrow on the battery cover on the back of the device.

While pressing down on the arrow, slide the cover towards the bottom of the recorder until it clicks.

Lift the cover and remove the batteries.

Remove the battery cover by first tilting it so it is at a right angle with the rest of the device.

Next, twist it to the side as shown in the second picture. The lid should simply snap off.

Use a #00 Phillips head screwdriver to remove the four (1.7x16 mm) screws from the back case.

Next, use the same screwdriver to unscrew the (1.7X5 mm) screw, which is located inside the battery compartment.

Use a spudger to push in the two tabs located on the bottom of the device.

It works best to push the tabs at an upward angle (towards the top of the battery compartment)

It may take a decent amount of force in order to push in the tabs.

With a firm grip on the larger half, remove the back cover by lifting first on the battery area.

The back cover should lift cleanly off.
