E.5 Activating Manta Logging
To initiate Logging, you must “activate” Logging by clicking the “Manta2 Logging is OFF” Hot Button so
that it changes to “Manta2 Logging is ON”.
Then all you have to do to start Logging for Trimeter and Manta 20, 25, and 30 models is load batteries.
For convenience, you may wish to take a Data Display to the field so that you can activate Logging right
before you place the Manta in the water. Don’t forget to activate Logging.
All you have to do to start Logging for Manta 35 and 40 models is load batteries and, when you get to the
field, turn the IBP switch on the top cap to “ON”. Don’t forget to activate Logging.
Don’t forget that the blinking green LED tells you that you have adequate voltage to begin logging, and
the blinking red LED tells you that Logging is indeed enabled.
E.6 Am I using Battery Pack power or cable power?
Most users log data using an Internal Battery Pack (IBP) or External Battery Pack (EBP). But you can also
log using power from a secondary power source (such as a solar-recharged storage battery located above
the water surface) via the Underwater Cable. If you have an IBP or EBP and a secondary power source
attached, the Manta will use power coming from the secondary power source as long as its voltage is
sufficient. If the Manta cannot find adequate voltage in the Underwater Cable, it will use the IBP or EBP.
This scheme preserves your Manta batteries when possible. Other manufacturers, for reasons unknown,
use the power source with the highest voltage, meaning that your Manta batteries may be consumed
quickly.
More information can be found in Manta Logging with an Uninterrupted Power Supply and Manta
Power Options.
