Old JR X347 Service mode question
Need to replace the lithium battery in my old JR X347. While waiting for battery to arrive have been in service mode to run thru it. Before calibrating the sticks it displayed a "C" in the center of the display, between the model name and the voltage. Now it shows an "F" in it's place. Assuming it means Fault?? How do I clear it? Or is it just telling me the lithium battery hasn't been replaced yet? Have found good info here, just not that piece. Thanks!
