Operation
Connect the sensor to the electronics using the sensor cable be-
fore turning the system on. Press the green ON button to turn on
the MUL . To turn OFF press the red OFF button. The RS-232
interface cannot be used to turn the MUL on or off.
To check battery condition press the BATT CHECK button and
the battery voltage will display on the LCD.
Place the sensor in the water using your towing arrangement.
As the sensor is towed across a target the audio output will in-
crease in pitch relative to the strength of the target. The bar graph
at the top of the display will also darken the bars to the left for a
negative polarity and to the right for a positive polarity.
Adjust the GAIN up or down as needed to maintain proper sensi-
tivity.
Towing the sensor horizontally will produce two peaks as the sen-
sor passes over a target. Towing vertically will produce one peak
over the same target.
When attaching the sensor to a tow rig, keep the sensor away
from ferrous metals. Although the sensor cable can be used to tow
the sensor, it is not recommended using it to tow a sled rig.
The sensor can be held by a diver to locate objects but will need
communication between the diver and the topside operator.
Although the electronics is water proof
*
, it is recommended that
it be kept out of the elements as much as possible. Water damage
to the internal parts is not covered under warranty.
