Page 4: General Comments
General comments The DX-300 is NOT a metal detector. It detects localised disturbances in the earth’s magnetic field that are caused by the presence of ferrous material. The user should note that other things can cause magnetic disturbances that will affect the DX-300 operation.
Page 5: Initial Testing Of Your Dx-300
This section explains the basic functionality of the DX-300 and how to use the controls. It is much easier to learn to operate the unit without the challenges of limited visibility, restrictive dive equipment, currents, etc.
Page 6 3. To prepare the DX-300 for use, plug the connector on the Sensor Probe into the SENSOR socket and screw down the retaining collar. This should be good finger tightness only.
Page 7 Test the operation of the DX-300 by walking slowly towards the target with the Sensor Probe pointed down at about 45 degrees rather than vertical to increase the lateral sensitivity.

DX-300 – DIVER HELD MAGNETOMETER User Manual 8. As you get closer and closer to the target, the DX-300 will begin to have constant audio output pitch, so you will need to lower the sensitivity to be able to actually pinpoint the target.
Page 9: Care And Maintenance
AUDIO control knob. Care and Maintenance Proper care of your Aquascan DX-300 will be repaid by a long and trouble free life and attention should be given to the following points: - 1. After use, and before removing plugs, make sure that the unit is switched off, and wash down with clean fresh water.
Page 10: Battery Care & Checking Battery Performance/Status
3. Recharge the batteries if the total hours used is approaching 10. 4. Never leave your DX-300 lying in the hot sun, as this could raise the internal temperature to the point where it may distort the case and harm the electronics.
Page 11: Troubleshooting Guide
No Response from DX-300 Module Check the following:- Check that the battery has been charged – If not, place DX-300 on charge and then re-test. Note. As the voltage drops below a certain point, erratic behaviour will result. Further decrease in voltage will result in total lack of functionality.
Page 12 DX-300 – DIVER HELD MAGNETOMETER User Manual Symptom: Erratic Performance from DX-300 Module First check as above. Check that the contacts of the bulkhead connectors are clean. Check that the connectors of the Sensor Probe and Bonephone are clean. If necessary reduce the contact resistance by slightly prising the gap in the male contacts, this will increase the firmness of the connector on insertion.
