The shorting pins near the Batteries/Super Capacitors will erase the memory when removed.
The two little switches near the edge will make it PERMANENTLY IN KEY MODE (SQUARE).
They were put there because some states have Tariffs that require systems with POOLS to have to pay more for their lines.
The others, I don't know. However, I do know that I have taken some CKE5's that didn't work, and made them work by putting the others in the right place. (As if, some one moved them around with out knowing what they were doing.)
Thanks Merlinman....I was interested in the little square
switch with 2 levers in the open position....found a processor with the switch broken off....just curious.
That makes me wonder if they are normally OPEN or CLOSED.
IF N-O that would mean being broken off would be no big deal.
Other wise who knows.
I got a MLX-408 card that only had 3 "TOP HAT" transistors (or what ever they were) at the top of the card, (instead of 4) guess what, it was really a 308, only 3 lines would work.
The little "dip" switch sets the system in either permanent "key" mode or allows switching between "key" and "Hybrid-PBX" mode. If the two switches are up - away from the edge connector - the switch can be in Hybrid-PBX or Key mode. If the two switches are down (towards the edge connector) - the system is set in permanent KEY mode. If one is one-way and one the other-way - the switch will not work at all.
The switch is NOT useless. Normally, both dip switches should be up. As I said - if one is up and one is down - the processor will not work at all. If your processor works fine - and you can choose "mode" in programming to what you want - then I would not worry about it.
