When you have determined that the contacts need replacing, perform the

operations described in the steps below. You will need the following

items to complete this procedure:

• 1/16-inch hex driver

• 0.050-inch hex driver

• Four new contact sets

1. Remove the configuration blocks from all four sides (see Figure 7-22).

2. Turn the board upside down. Use the 0.050-inch hex driver to

remove the two screws holding the programming block to the circuit

board. Be careful not to strip the screws.

3. Keep the module in the upside-down position and gently pull the

board from the programming block assembly (see Figure 7-23).
