5) Replace the top cap by screwing the eye-bolt back into the place where you found it. Note that the top cap can
only fit one way because the black indexing stud (above) must fit into the hole in the underside of the top cap.
Finger-tight is sufficient for the eye-bolt.
If your Manta 2 is not going to be used for a few weeks or longer, remove the batteries to prevent their leaking all over
the inside of the IBP. Put your Manta 2 into a clean plastic bag to protect any exposed seals.
Note:
Store at room temperature.
G7 External Battery Packs
The 2-, 2.5-, and 3-inch Manta 2’s use the optional Manta 2 External Battery Pack (EBP): a watertight (to 200 meters)
housing with a cassette for five or ten “AA” batteries and a data port. Remove the EBP to connect your Manta to a PC
for dumping logged data, or for calibrating the Manta sensors.
The EBP simply screws into the Manta multiprobe where normally you would find the cable and its locking sleeve.
One you have activated the Manta 2 logging (by clicking on the logging button on the Manta 2 Control Software’s main
page) all you have to do to start logging is connect battery pack to the Manta 2 top cap:
1) If a cable is attached to your Manta 2, remove the locking sleeve and then the cable.
2) Make sure all the o-rings and inner surfaces are clean and covered with a light film of silicone grease.
3) Twist the EBP onto the same threads formerly occupied by the locking sleeve – finger-tight is sufficient.
4) Make sure that the amber LED blinks every five seconds – it’s your assurance that the EBP has sufficient
voltage to power the logging function.
5) Make sure the red LED blinks every 2 seconds for 10 seconds upon each power up – it’s your assurance that
Manta 2 logging is enabled.
Your Manta 2 is now logging, and will continue logging until you remove the EBP, or your batteries are depleted.
Bad news: Batteries don’t last forever. Good news: You can buy 10 “AA” batteries at Sam’s or Costco for about $2,
and confidently install them in the EBP in about two minutes. All you need are the new batteries and a paper towel.
When you change the batteries, please:
1) Replace all batteries at the same time, and use the same brand of battery.
2) Clean all dirt and stuff off the EBP, because you are going to expose sealing surfaces as you change the
batteries.
3) Grab the EBP bottom cap (the black plastic cap just below the clear housing) and unscrew the housing by
twisting it counter-clockwise. Don’t take the housing all the way off; just open it wide enough to replace the
batteries,
4) Remove the spent batteries, and install the new ones following the polarity labels.
5) Twist the housing back onto the EBP bottom cap – finger-tight is sufficient.
If your EBP is not going to be used for a few weeks or longer, remove the batteries to prevent their leaking all over the
inside of the EBP. Put the EBP into a clean plastic bag to protect any exposed seals.
Note
: Store at room temperature.
