Symbol Technologies LS 3070 Manuale Utente

1. Ensure that the NCR 280 is powered down and unplugged. Open the door 

on the top, left-hand side and remove the two screws which fasten the steel 
plate to the terminal cover. Slide the steel plate to the left to remove.

2. Remove the two round head screws from the back of the terminal. Be sure 

the doors on the left and right side of the terminal are open and that there 
are no keys inserted in the locks on the front. Lift off the terminal cover.

3. Locate the card edge connector to the left of the keyboard. Mark the top 

side of the connector before removing it from the keyboard.

4. Remove the four “C” clips that hold the keyboard in place. Remove the 

keyboard.

5. Feed the end of the RL 470 base station cable with the 2x8 header connector 

under the large capacitor mounted horizontally in the terminal power 
supply. Next feed the cable between the two large vertically-mounted 
capacitors then through the hole in the plate adjacent to these two 
capacitors. Feed through enough cable so that the cable reaches the 
terminal keyboard.

6. Mate the 2x8 header connector to the connector on the interface board. 

Note that pin 10 is keyed.

7. With the component side up on the interface board, connect the card edge 

connector on the interface board to the card edge on the keyboard. The 
interface board will be mounted under the keyboard PC board.

8. Connect the card edge connector, removed earlier from the keyboard, to the 

interface board, with the marked side facing down.

9. Replace the keyboard with the interface board attached. Be sure the 

interface board is installed so that it doesn't interfere with any cable 
assemblies. Replace the “C” clips.

10. Remove any slack in the RL 470 base station cable by gently pulling it back 

through the terminal power supply.

11. Using the cable tie provided, secure the base station cable to the cable 

bundle near the capacitor, which is mounted horizontally approximately 6 
1/2 in. from the rear of the terminal.
