Replacingtheinternalbattery
If you have verified that the batteries need to be replaced, follow
these steps to do so:
1. Open the lid of the RA440 by unscrewing the four bolts in the
corners of the unit and opening the lid onto the right side, as
shown in Figure 3 on page 11 and Figure 4 on page 11.
2. The battery packs are connected to the electronics board by
means of a PCB connector. Remove the plug of each pack from
the PCB connector, as shown in Figure 9.

3. Loosen all four screws of the battery holder that keeps the
batteries in place, then remove the cover and the batteries.
4. Remove the expired battery packs and replace them with new
ones (obtainable from Adcon).
5. Replace the battery packs and the battery holder and fasten the
four screws.
6. Insert the battery plug of both PCBs into the PCB connectors.
0 WARNING Be sure to mount the rubber gasket properly, so that the unit’s IP65
environmental protection is not affected. You must also be sure to not
squeeze the battery cable.
7. Close the lid, taking care that the rubber gasket sealing the box is
correctly in place and free of dirt and soil.
8. Put the four cover bolts back in place, applying a moderate force
and tightening crosswise.
