Fig. 8.2 shows in a side view of the CMX-PS the connections on the screw connectors that could be accessed on the
back of the device.
Fig. 8.2 is side view of the CMX-PS with the cover removed. You need to remove the cover to access the batteries. To
remove the cover, unscrew the three cross-headed screws on the aluminium cover with holes and lift it. You can see
the batteries and the electronic circuitry.
The two sealed batteries (6 V-2.0 Ah) are connected in series. one cable runs from one to the other, connecting the
positive and negative poles. The negative pole from one battery must be connected to the cable with the BLU band, that
is connected to the power supply PCB. The positive pole of the other battery must be connected to the cable with the
RED band, that is connected to the front switch. The cables are Faston terminated, so the battery replacement is
matter of minutes.
