Replacement Of The Program Module


All information which is stored in the indicator will be lost and cannot be retrieved when the program module is changed.

If it is desirable to save this information it MUST be recorded before changing the module.


The program module is packaged in a container to protect it from static discharge.

Before touching the module in the container, or removing from the indicator, be sure to discharge any static electricity in your body by touching a grounded surface.

This will disconnect the batteries from the indicator to prevent damage while changing the program module.


Remove the Program Module with fingers ONLY by pulling up on the tabs on each end of the Program Module.

Do not use any mechanical tool to remove the Program Module or damage may occur.

4. Locate and remove Program Module (4) in the center of the large printed circuit board above the batteries.

5. Install the new Program Module into the empty socket.

NOTE: The Module and socket are keyed so it can only be installed in the correct (seated) position.

6. Locate the two bare pins which are still attached to the printed circuit board on connector (3) which were separated in Step 3.

Use a screwdriver or paper clip to short these two pins together for at least thirty seconds.

This will reset the indicator microprocessor.

Then connect the two halves of the two-pin connector back together until they snap in place.

7. Install rear cover (2) and replace six screws (1).

8. Turn the indicator ON and check for correct operation.

NOTE: Display will show "memory passed" briefly before start up display is visible.
