Ocean Observer Direct Reading Technical Manual

Static electricity can damage board components. TRDI recommends using an earth-grounded

wrist strap to help prevent such damage. You must have the wrist strap on whenever the TSIB

cover is removed.

Remove the TSIB top cover:

1. Turn off power to the TSIB. Disconnect all cables from the back panel of the TSIB.

2. Remove the TSIB top cover. The cover is held in place with four screws on the corners of the cover. Re-

move all screws and retain them.

3. Lift the cover slowly.

Do not break the grounding wire attached to the cover.

4. A grounding wire is attached to the underside of the top cover. Unplug the ground wire from the tab on

the top cover and lift off the cover.
