Maintenance
Keep the unit as clean as possible, especially the Electronics key-
pad panel. Do not use an abrasive cleaner on the keypad overlay
or the LCD lens.
The Titanium encased sensor has no user serviceable parts. In the
event of a failure, the sensor should be returned to the factory at
the address listed at the end of this manual.
The battery and charging circuit are located inside the electronics
unit and should not need servicing for quite some time. In the
event that the battery weakens or fails, return the unit to the facto-
ry for replacement.
Battery Charging:
Connect the wall transformer to the CHARGE connector located
on the right side of the case. The Red LED will illuminate during
charging and will extinguish when the battery is fully charged.
While plugged in it will provide a trickle charge but the LED will
be off.
Repair Service:
Should you need to return the system to the factory for service,
send it to the address listed on the last page of this manual. Pack
the unit properly to protect it during shipping. No authorization is
necessary. Please include all your company information for re-
turning the unit.

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 BHG . To turn OFF press the red OFF button. The RS-232
interface cannot be used to turn the BHG 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 case is water proof when closed, it is
recommended that it be kept out of the elements as much as pos-
sible when open as water could seep through the foam. Water
damage to the internal parts is not covered under warranty.
