Next, take out one battery at a time and quickly replace it with a new battery before removing any other batteries. Keep replacing one battery at a time until all batteries have been replaced. - Alternatively, when changing batteries, you might want to plug a "plug pack" into the RCX's AC adapter connection. Radio Shack sells an inexpensive 6xAA pack with a 9V clip on top and a cable that plugs into the RCX. KAB    :    : * : * :   I seem to lose firmware all the time - what's going on? Can I use rechargeable batteries in the RCX? Why can't I load the new ROBOLAB 2.9 firmware onto my RCX? Does ROBOLAB 2.9 preserve on-brick programming for the NXT? Why do my RCX sensors change values over long periods of time?
