I recently purchased an 850 controller with a repeater. The controller did not work when I powered it up. Upon inspection, I found that the MX- 4 memory board (aftermarket I assume) had come unplugged from the main board. My question is, which way does it plug in? The connector is not keyed. The MX-4 sits perpendicular to the main board. So, does the board sit over the top of the main board, or the other direction, facing the phone patch board? I have no documentation for the MX-4 so I am a bit in the dark. Thanks in advance. John AB6LI ------------------------------------ Yahoo! Groups Links -- No virus found in this incoming message.
