AQ1B Compact Underwater Metal Detector
User Manual
voltage will drop gradually, but performance is not affected until the voltage
drops below 9.6 volts. Once the voltage falls below 9.6 volts it will drop at an
accelerated rate. The detector will not function correctly if it goes down
around 8 volts or lower. If you measure the voltage and it is near or below 9.6
volts, it’s time to re-charge the battery pack.

Checking Battery Pack Performance
Note: If you feel you are not getting proper performance from your battery pack,
you should perform this battery pack test.
The recommended procedure is as follows: -
1.0
Connect an Aquapulse Loop or Probe to your AQ1B-Compact module.
1.1
Power on your AQ1B-Compact (MIN position – one click clockwise from
OFF) and leave it on overnight to fully discharge the battery.
1.2
Power off the AQ1B-Compact and disconnect the loop.
1.3
Charge the AQ1B-Compact for a14 hour period. The mains re-charger
supplied has an intelligent sensing device that senses the battery state and will revert
to a low current charge once the battery state is sensed as fully charged; it also has a
timeout function that drops to the low current state after 14 hours if the fully charged
state is not sensed in the meantime. The latest type of charger is identified by the
multicoloured LED and its direct connection to a mains socket. The predecessor to the
current charger had a single state GREEN LED and a mains connecting lead, this
version timed out after 6 hours and required to be switched off then back on to start a
second 6 hour charge period followed by again resetting the power and allowing a
final 2 hour top up to ensure a full charge is achieved.
1.4
Once the AQ1B-Compact is fully charged, disconnect the charger from the
Mains and then disconnect it from the AQ1B-Compact.
1.5
Connect an Aquapulse sensing loop and Bonephone or Headphone to the unit
and switch it on to the MIN position. Set the loop up away from any metal
and adjust the SET AUDIO control to get a steady slow clicking sound.
