TROUBLESHOOTING GUIDE
Symptom:
No Response from AQ1B Module
Check the following:-
1.
Check that the battery has been charged -
If not, place AQ1B on charge and then re-test.
2.
Check that both Sensing Loop and Bonephone are correctly connected
Try using an alternative Bonephone/AQ1B Headphones.
Try using an alternative Loop or a known good AQ1B Probe.
3.
Check that both the Sensing Loop and Bonephone are in good
condition. Check by substitution if possible or by monitoring the
nominal resistance of both items. 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 AQ1B Resistance Chart below: -
Symptom:
Erratic Performance from AQ1B Module
1.
First check as above.
2.
Check that the stainless contacts of the bulkhead connectors are clean.
3.
Check that the stainless connectors of the Sense loop 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.
4.
Check that the cable to the Sense Loop has not been damaged causing
water ingress.
5.
Check that the male connector seals are in place and clean.
