Figure 7-3. Removing the A6 Front Panel Assembly
A6A1 Display and A6A2 Keypad PCAs
Use the following procedure to remove the A6A1 Display and A6A2 Keypad PCAs:
1.
Remove the A6 Front Panel Assembly from the Instrument.
2. Remove the Spin Wheel. There are 2 holes in the bezel moulding, visible from the
inside face. These holes allow for using a thin screw driver shaft to push the Spin
Wheel moulding from the encoder shaft.
3. Remove the retaining nut.
4. Lay the front panel face down on an antistatic surface and disconnect the display
cable from the HV drive module. The PCA is extremely thin; use care during the
removal process.
5. Remove the four self-tapping screws from the display and lift it out, taking care not
to scratch the display or window.
6. Remove the eight self-tapping screws securing the Keypad PCA to the front panel.
Lift out the Keypad PCA ensuring the spin wheel device remains attached. Note the
bottom edge of the Keypad PCA connects to the front panel. Use a slight forward
pressure to remove the PCA.
7. Lift out the rubber keypads.
Note
The display window is secured in place by adhesive tape. Do not remove
the display unless it or the display window is being replaced.
Note
The inside of the front panel has a nickel conductive coat applied to it. Be
careful to avoid damaging the coating.
