Not used for more than 3 months • Do not leave the batteries at full charge or
discharged for a long period of time or they
will wear out.
• Every 6 months, put the sensor in charge
for less than an hour.
Every 2 years The sensor must be returned to an approved Mar
port dealer for inspection and maintenance.
If the sensor has not been not used for more than 3 months, we highly recommend to
check the following points before using it:
• Make sure the sensors on the end cap are in good condition and clean.
• Connect the sensor to a charger and check the charging status.
• Switch on the sensor by shorting the center lug to the negative lug, then listen for
a ping noise and check if you see the LED switched on.
• Test the sensor measures with Mosa2: depth, temperature, pitch, roll, and if
applicable: spread distance, echogram, catch status, speed measures (using the
EM log tester).
• If you have a test hydrophone, check the reception in the wheelhouse with Scala.
