The Sentinel V loose-battery housing uses 12 D cell alkaline batteries.
Ensure that proper polarity is observed when installing batteries.
Do not mix old and new batteries.
Do not mix alkaline with non-alkaline batteries.
Do not use damaged batteries.
Do not mix batteries of different brands.
Do not use expired batteries.
Do not leave the batteries inside the Sentinel V for extended periods. The batteries may leak,
causing damage to the electronics.
Store the batteries in a cool, dry location (0 to 21 degrees C).
To replace the D cell batteries:
).
2. Remove the battery cover plate by loosening the knob (rotate counterclockwise).
3. Slide out the used batteries.
4. Slide in the new batteries starting with the three batteries in the center with the negative side up.
Next place the other three batteries with the negative side up. Place the last six batteries on the
outer edges with the positive side up. See Figure 56 for battery orientation.
5. Ensure all batteries are fully seated by pushing them all the way down into the battery cavity.
6. Position the cover plate over the batteries.
7. Tighten the knob firmly until the cover plate is flush with the
surrounding
surface to hold the bat-
teries in place.
8. Replace the desiccant (see
).
9. Install the end-cap (see
). As the end-cap is placed on the housing, check
the cables lay flat and do not become pinched.
Check that no wires or any other object is pinched between the End-Cap and the housing. If
the O-ring is not in the groove or if a wire or other object is pinched, the Sentinel V ADCP will
flood.
If the battery cover is loose, the D cell batteries may make intermittent contact or it may
interfere with the end-cap properly closing. Tighten the knob until the cover plate is flush
with the
surrounding
surface.
10. Use the
panel to set the date the batteries were replaced.
