To Disassemble the ADNK-3043-ND24 Unit
The ADNK-3034-ND24 comprises of the plastic mouse
casing, a main printed circuit board (PCB), lens, buttons,
and a 2.4 GHz RF daughter card, and a 2.4 GHz USB
receiver dongle. (See Figure 4.) Removing the screws
located at the base of the unit separate the top and the
bottom of the mouse casing. Removing the PCB assembly
from the base plate further disassembles the mouse unit.
Be careful with the battery terminals while separating the
PCB assembly with the bottom casing.
While reassembling the components, please make sure
that the Z height (Distance from lens reference plane to
surface) is maintain. Refer to Figure 5.
