Should an X2-CB or iSIC-CB need to be sent in for evaluation or repair, please reference the following steps for removal:
Tools Required– 9/16″ Socket Wrench
1. Disconnect the 6-pin solar panel cable from the X2/iSIC-CB SOLAR port to remove power from the data logger.
2. [For CB-150, 450 buoys only] Remove the buoy’s solar tower to gain access to the data well.
- Remove the (6) 3/8-16×3/4 bolts and 3/8 lock washers holding the solar tower to the buoy using a 9/16 socket wrench
3. Remove the (8) 3/8-16×3/4 bolts and 3/8 lock washers from the X2/iSIC-CB or data well pass-through plate using a 9/16 socket wrench, loosening them in a cross pattern.
4. Lift the X2/iSIC-CB plate off of the data well.  Disconnect the 6-pin UW-plug running between the solar regulator and the iSIC-CB. This will expose the data well where the battery and solar regulator are installed.
5. Pack with plenty of protective material and ship the X2/iSIC-CB to:
NexSens Technology, Inc.
2091 Exchange Court
Fairborn, OH 45324
(937-426-2703)
6. For deployed systems it will be necessary to protect the data well and system batteries while the logger is being evaluated. In most cases, NexSens will provide a blank plate to maintain a water-tight seal.
7. Inspect the large o-ring on top of the data well.
a. Clean any debris that may have accumulated on top
b. Inspect for any tears or abrasions on the o-ring surface, replacing if required.
c. Ensure the o-ring is well greased. Each buoy maintenance kit will have a tube of this for use.
8. Cap the loose 6-pin solar cable remaining in the data well if possible to keep it clean and dry.
9. It is recommended a new bag of desiccant be tossed into the data well at this time.
10. Â Install the blank plate.
a. Place the blank plate over top the data well and align the holes.
b. Re-install the  (8) 3/8-16×3/4 bolts and 3/8 lock washers from the X2/iSIC-CB or data well pass-through plate using a 9/16 socket wrench, tightening them evenly in a cross pattern to ensure an even o-ring seal.
11. Ensure that all sensor port receptacles on the blank CB-plate are occupied with a hand-tightened dummy plug or a sensor cable plug from any of the deployed sensors. Additionally, verify each plug and receptacle have a clean O-ring.
