DX-300 – DIVER HELD MAGNETOMETER

If the performance becomes unacceptable after less than what you (the

operator) determine to be an acceptable minimal operational period, then the

DX-300 Battery Pack needs to be replaced.

Note: If your battery needs to be replaced please contact our technical support dept

to arrange for an installation of a replacement battery, or in the case of an

approved service agent please refer to the servicing data provided.

Please consider NiMH batteries as hazardous material and dispose of your old

battery pack in line with local guidelines.

Troubleshooting Guide

Symptom:

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.

Check that both Sensor Probe and Bonephone are correctly connected

Try using an alternative Bonephone/AQ1B Headphones.

Try using an alternative Sensor Probe if available.

Check that both the Sensor Probe and Bonephone are in good

condition. Check by substitution if possible or by monitoring the

nominal resistance of Bonephone/Headphones. Connecting a good

quality multi-meter across the pins of the plug can check the resistance.

NB. It is good policy to firstly check the multi-meter's reading with the

leads shorted together - this provides a measure of what residual

reading to take into account.

>See DX-300 Resistance Chart below: -

There is no user test for the Sensor Probe other than visual mechanical

inspection. Inspect the connector and cable, looking for any signs of

damage that could allow ingress of water into the cable or connector.
