Once the screws are removed be cautious while removing the cover as antennas cables are connected to the RM520N modems.

Once the robot is opened (and still powered off): If your robot has just one RM520N, it should be located at SLOT 0. In that case, there is nothing more to do inside the robot and you can carefully close the robot and screw the cover back on. If you have two RM520Ns, as only the one in SLOT 0 will be safely upgraded, disconnect the modem in SLOT 1 by removing the screw which attach the modem to the SLOT, and, without disconnecting the antennas from the modem, remove the modem from the slot. You will do the same operation with SLOT 0 and insert the modem which was in SLOT 1 into SLOT 0. In any case, to properly execute the update procedure, only one RM520N should be inserted in the robot.

Once the robot is ready with the RM520N modem to be updated inserted in SLOT 0, it can be powered on.
