6.
Plug in the charger to a 110-240 V AC 50-60 Hz socket.
7.
If you have the multi-charger, turn the power switch to the
ON
position.
The power switch lights on. If not, check the AC power cord connection.
8.
Wait for the battery to charge: standard charging cycle takes 8 to 12 hours. A fast charge
configuration allows a 70 % charge in 1 hour and full charge in 4 hours.
9.
Look at the LED(s) on the charger box to know the charge status. For the multi-charger, there is
a LED for each sensor charging cable. The charge status are:
•
Green LED: > 90 %
•
Orange LED: from 70 % to 90 %
•
Red LED: < 70 %
Note:
If the sensor is in configuration mode, it will begin to charge after 10 minutes. As
long as it is in configuration mode, the charger's LED remains red, whatever the charge
level.
10.
Make sure to disconnect the charger from the sensor when you switch off the charger or
vessel's power supply. If not, the contact of the charger's pins with the shoulder bolts switches
on the sensor, that will run until discharged.
Results
Once charged, the operational life time can be up to approximately 75 hours.
The operational life time depends especially on the uplink power of the sensor, but also on the
sounding range, uplink frequency and options activated.
Cleaning the Sensor
You need to regularly clean the sensor for proper performance.
Wash the sensor with fresh water before you charge or store it.
Regularly check that the sensor is clean. If not:
• Remove any marine life with a piece of wood or screwdriver.
• Wash away mud or debris with warm water.
CAUTION:
Do not use highly abrasive materials or jet wash.
CAUTION:
Special care should be taken with sensors and components sensitive to
mechanical shock or contamination.
