Rio Karma
Our first device to be dismantled, the Karma, was chosen because dust had begun to accumulate between the screen and the LCD display.
The first step is to remove the two screws on the base of the Mp3 player. Order is not important this time, but as usual, be careful not to scratch the device.
After the screws are removed and stored safely (in a cup or other such vessel), the next step can be performed. Pinch the dark gray thumb rest near the screen and pull out to the right, to remove it from the device.
Now the innards of the Karma are exposed, you will see another small screw located to the right of the RioStick (the red trackpoint.) Remove it.
This next step is to be performed very carefully. Gently wiggle a small flathead screwdriver or device between the two main halves of the Karma. Be careful not to force it too much, or to push it in too far, as this may cause permanent damage. Continue wiggling the wedge, and slowly sliding it down the seam until the two halves totally separate.
It is important that the battery is not removed at this point. Doing so will tear the wires and ruin the Mp3 player.
If the battery is lifted lightly, you can see the hard drive resting underneath.
Do not remove the two screws holding the hard drive together. Notice that there are now two screws sitting outside the perimeter of the hard drive, Not the screws attached to it!!!
Removing the screws near the edge of the PCB screws will allow the entire PCB-HDD-Battery module to be removed from the case.
The RioStick can now be removed, but it is not necessary to do so.
To remove the battery, gently separate the PCB located on the top left from the main PCB. To do this, use both thumbs and forefingers, and pinch the PCB on both sides. Rotate your fingers towards the PCB, so that they push against the main chip and separate it from the main chip. (In effect, use your fingers to pry it up, using the main PCB as the fulcrum.)
That’s it!
To reassemble, align the pins on both PCBs and gently press them together, the rest is pretty easy. Note: Make sure the hold and volume buttons are properly aligned between the case and the PCB. If they are not, it will cause damage. Also, the positioning of the Riostick is important to proper function; it must be replaced in the same way it was taken off.
When closing Karma’s case, the two halves should be first joined at the top, and closed in the same manner used to close a pizza box.
