The MD3 modem has a 4-pin and a 10-pin DIL switch. The 10-pin DIL switch, SW2 is
located directly on the top housing grill. The 4-pin DIL switch, SW1, can also be reached
from above through the housing grill, however it is located deeper within the housing and
may therefore be more difficult recognize. To set this switch, you require a long, thin tool, for
example a small screwdriver or a toothpick.
The DIL switches have the following functions:
