5.7.3 Changing IBP batteries in Scuba 90 and 105 model and activating logging
1
Replace all batteries at the same time and use the same brand of battery.
2
Clean all moisture, dirt, grit and any other debris off the Scuba because you are going to expose sealing surfaces as
you change the batteries.
3
Unscrew the eye-bolt until you are able to
completely remove the battery plug.
4
Remove the spent batteries and install six C-cell
batteries carefully following the polarity diagram.
5
Clean all moisture, dirt, grit and any other debris
off the exposed O-ring surfaces and the inside of
the battery tubes. Add a small amount of silicone
grease to the O-rings and to the inside of the
battery tubes where the O-rings will seat.
6
Re-attach the battery plug by turning the eye-bolt.
You don’t have to tighten it closely to the Scuba;
finger-tight is fine.
7
Remember that you must first activate Scuba logging by clicking the “
Scuba Logging is OFF
” hot button so that it
changes to “
Scuba Logging is ON
” (3.3, 5.5).
8
When you are ready to deploy the Scuba, turn the battery switch to “
ON
”. (And turn the switch back to “
OFF
” when
you retrieve the Scuba).
9
Remember to look for the red LED to blink five times to confirm that logging is activated, and the green LED blink
briefly to confirm that the Scuba is receiving adequate voltage to start logging.
10
Your Scuba is now logging and will continue logging until you turn the battery switch to its “
OFF
” position, or your
batteries are depleted.
5.8 Logging with an external battery pack
5.8.1 The external battery pack
All Scuba models (except the Scuba 90 and 105 models with Internal Battery Packs) can utilize the optional External
Battery Pack (EBP), a watertight housing with a cassette for batteries that can be removed from the Scuba. Most EBP’s are
used for logging, but they can also be used to power the Scuba while it is connected to a data display if the data display
cannot provide sufficient power.
The EBP simply screws into the Scuba multiprobe where normally you would find the underwater cable and its locking
sleeve. The EBP is installed immediately before a logging deployment, and later removed so your Scuba can upload data
to a data display or be calibrated.
