Access to Board Settings

To gain access to the settings for the electronics, the rear door of the model opens up. However, several people have reported having problems opening that door.

Rich Gajnak reports that the rear door is a very tight press fit with a magnet on top to hold it from falling out. On his B-unit, he was able to get a single-edge razor blade between the door casting and the body from underneath. There is a fine separation line visible underneath. The coupler has to be removed to do this. The razor blade gave enough leverage to pop the door a little, and then be pulled off.
