8-114 Section 8-29 - Alpha-Numeric (A/N) Keyboard Replacement Procedure
Section 8-29
Alpha-Numeric (A/N) Keyboard Replacement Procedure
The A/N Keyboard can be replaced without removal of the operator panel from the frame.  The screws 
for removal are hidden under the “return” and left “shift” keys.
8-29-1 Manpower
8-29-2 Tools
A key removal tool is required. Acquire a commerical key removal tool or fashion two loops made from 
paperclips as shown in Figure 8-123 on page 8-114 .
8-29-3 Preparations
1.) Power Down/Shutdown the system as described in Section 4-3-2 on page 4-3
8-29-4 A/N Keyboard Removal
1.) Place the loops under opposite corners of the key to be removed as shown in Figure 8-
124 on page 8-115 .  To remove the AN keyboard, the “return” and left “shift” keys must be 
removed. 
2.) Pull up with the tool but also slightly to the top edge (number row) of the keyboard.  The slight pull 
towards the top forces the white plunger to come off with the key.  If using paperclips, it works best 
if you use one hand on each clip and pull together.
3.) If the white plunger stays in the keyboard, you can reinstall the key and try again. Or, the plunger 
can be removed from the keyboard needle nose pliers grabbing between the same points as where 
the key inserts.Figure 8-123  Key Removal Tools

5.) With the “return” and left “shift” keys are removed, you can see the screws that secure the keyboard 
to the plastic bezel.  Loosen these screws so that they pop up but do not remove them as they are 
captive screws that remain with the AN keyboard.
6.) Using the key removal tool, lift up on a key to help pull the AN keyboard out of the plastic bezel. 
Choose a key to the  far right and lift the right side of the keyboard out first. 
7.) Lift out the bottom edge of the keyboard bar to gain access to the interconnect cables.  Detach the 
2 cables from the keyboard and lift  the keyboard out.Figure 8-126  Keyboard Screw Locations

8.) Install the removed keys back onto the removed keyboard.  If a key does not seem to seat down 
fully, it is probably because the plunger is not pressed onto the keytop all the way.Figure 8-127  Interconnect Cable Locations

8-29-5 A/N Keyboard Installation
1.) Using the key removal tool, remove the “return” and left “shift” keys from the replacement keyboard. 
use the same procedure as before. Make sure that the plungers come off with the keys and that 
they are fully seated into the keytop after removal.
2.) Check the replacement keyboards rubber gasket. When seated correctly, it should wrap around the 
edge of the circuit board.  If the gasket is not seated correctly, the keyboard will be difficult to install.
3.) Connect the cables to the replacement keyboard.  Check that the cables are not shifted by one row 
of pins as this is possible to do.
4.) Insert the keyboard left side first making sure the gasket remains seated around the circuit board.Figure 8-128  Keyboard Gasket

5.) Continue to work the keyboard down into the plastics slightly pushing to the left so that the gasket 
on the right side goes into the plastics without getting disturbed. 
6.) Seat the keyboard fully by pushing down on the whole keyboard with both hands.
7.) Check the function of the keys around the keyboard edge.  If keys stick or have a bad feel. the 
gasket probably got disturbed and is not around the edge of the circuit board. Remove the keyboard 
check the gasket and try again.
8.) If the keyboard is seated correctly, secure it with the screws.
9.) Reinstall the keytops. If a keytop seem too high, the white plunger was probably not seated all the 
way into the keytop. The keytop and plunger must be removed to fully seat the plunger into the 
keytop.
10.) Energize the system and type with the keyboard to check the function of each key.Figure 8-129  Replacing Keyboard
