Programming the acoustic sampling


Sequence

Open the canister unscrewing the cap with the hydrophone.
Do NOT open the bottom end with GPS transponders unless necessary.
If batteries are known to be good (based on previous experience and a battery life data record and/or the battery life estimator) you can restart and reprogram using the provided big magnet from outside the canister. Place it near the golden metal spot near the serial number label and the unit will be hard-powered-OFF.

When removing the magnet you will see the blinking lens and you will be able to reprogram the unit as described below without opening the unit.

Check the batteries and change them if WEAK when tested with a tester.
