Removing Natural/White Keys
1. Unlock the key from the pivot anchoring the key to the keyboard chassis. To do this, insert
a small
fl
at screwdriver at the back end of the pivot and press toward the front edge of the
keyboard. While doing so, lift the back end of the key.
2. Remove the screwdriver.
3. The key should now be free of the pivot. Lift the key up slightly, then forward. The front
edge of each key hooks under the keyboard chassis. Be sure the key is not hooked under
the keyboard chassis prior to lifting the key off.
Caution
: Each key has a small key spring. The key spring is positioned on the keyboard chassis
(just in front of the pivot) and is held in place when the key is installed. When you remove a key,
be sure you do not misplace the key spring.
Removing Sharp/Black Keys
1. To remove a sharp key,
fi
rst remove the adjacent natural keys, as described in the previous
procedure.
2. Unlock the key from the pivot anchoring the key to the keyboard chassis. To do this, insert
a small
fl
at screwdriver at the bottom of the pivot and press toward the front edge of the
keyboard. While doing so, lift the back end of the key.
3. Remove the screwdriver.
4. The key should now be free of the pivot. Lift the back of the key up slightly, then forward.
The front edge of each key hooks through the keyboard chassis. Once the key is free of the
pivot, you should be able to lift the key out from the keyboard chassis.
Caution
: Each key has a small key spring. The key spring is positioned on the keyboard chassis
(just in front of the pivot) and is held in place when the key is installed. When you remove a key,
be sure you do not misplace the key spring.
Replacing a Sharp Key
Note:
Always replace a sharp key before replacing the adjacent natural keys.
1. Verify the placement of the key spring.
2. Position the front end of the key through the keyboard chassis.
3. Lower the key into position. Align the pivot with the hole at the rear of the key.
4. Push down on the key. It should snap into position onto the pivot.
