T o in st al l so ftw ar e if all el se fails (boo t sector update)
Note: Use this procedure only if the firmware is totally corrupted, which is evident if the control panel does
not respond when power is applied, or if the software update notes call for a boot sector update. In the event
of a check sum error, repeat the normal upload procedure.
1. Disconnect the fixture from power.
2. Remove the side cover from the side of the base that has the control panel to expose the main PCB.
3. Locate the "BOOT" jumper on the main PCB (see page 40) and move the jumper cap to the "INIT"
position.
4. Perform a boot mode upload as described in the uploader documentation.
5. When the upload is complete, disconnect the fixture from power and move the jumper back to the
"DISABLE" position.
6. Reassemble the base.
