Axm-Mlc (/Pb) And Axd-Mlc (/Pb) Eprom Replacement - panja Black/White LCD Instruction Manual

Upgrading the Firmware
8. Using the new EPROM, match up the socket holes to the respective prongs and the notch to the
correct direction for the new chip.
9. Insert all the prongs simultaneously until each is firmly resting in its socket hole and the entire
chip is securely connected to its base.
10. Rotate the circuit card back to the original position and place it in the touch panel housing.
11. Plug the AXlink connector back into the touch panel for approximately 1 minute. Once you
can confirm that the panel is receiving power, remove the connector, align the screw hole and
insert the Phillips-head screw and tighten.

tighten.
13. Plug all connectors back into the touch panel.

If the unit is already mounted to a surface, remove it at this time. Refer to the Installation section on
page 3 for more information.
1. Discharge the static electricity from your body by touching a grounded object.
2. Remove the 4-pin AXlink connector from the rear side of the touch panel.
3. Flip the touch panel face down onto a soft cloth, and remove the seven Phillips-head screws
from the bottom panel. Then, gently remove the housing.
4. Remove the Phillips-head screw located in the center of the circuit card.
5. Gently tilt the circuit card down towards the connector side and pull backwards until you clear
the connector housing. Then, slowly rotate the circuit card backwards until you can lay it down
flat with the EPROM exposed as seen in FIG. 19. EPROMS have stickers that indicating the
firmware version.

6. Carefully remove the EPROM by inserting a Phillips screwdriver with a non-conducting flat-
blade between the EPROM and the connection site (at the notch side).
7. Gently pry the EPROM from their connection base until it begins to loosen. Carefully pull the
chip out by either using a EPROM removal device or by gently pulling it from the base
