5.2 Instructions for Replacing Parts

Replacing a Digit

Do not attempt to remove individual LEDs, but rather replace the entire digit panel. To remove a display

digit, follow these steps:

1. Open the display panel as described in Section 4.1.

2. Disconnect the power connector from the back of the digit. Release the connector by squeezing

together the locking tabs and pull the connector free.

3. Remove the #6-32 Keps nuts that hold the digits to the inside of the panel.

4. Remove the digit.

5. Position a new digit over the screws and tighten the nuts.

6. Reconnect the power connector.

Note: This is a keyed connector - it will attach in one way only. Do not attempt to force the

connection.

7. Close and secure the digit panel and test the display.

Replacing a Digit Segment

The larger digits (24") are constructed in segments, as shown in Figure

16. In this case, make repairs by removing only the defective segment.

Do not attempt to remove individual LEDs. To remove a digit segment,

follow these steps:

1. Open the digit panel as described in Section 4.1.

2. Disconnect the two-pin power connector from the back of

the individual segment. Release the connector by squeezing

together the locking tabs and pull the connector free.

3. Individual segments are secured to the inside of the panel with

fixed machine screws, spacers, and push nuts. Remove the

nuts and lift the segment off the standoff screws.

4. Position the new segment over the screws and tighten the nuts.

5. Reconnect the power connector. Note: This is a keyed

connector - it will attach in one way only. Do not attempt to

force the connection.

6. Close and secure the digit panel and test the display.

Replace a malfunctioning colon, decimal, or indicator assembly in the

same manner.
