AQ1B Compact Underwater Metal Detector
User Manual
disconnecting the cables, you can clean out the socket with a cotton swap and
wipe off the plug pins with a soft rag. Ikelite does not recommend using silicone
grease or any other material on the connectors. The rubber seal provides
adequate isolation of the connectors from the water. Use of these type products
tends to accumulate sand and other debris which can actually interfere with the
seal and the signal transmission.
NEVER utilize petroleum products such as
Vaseline on the rubber seal; these will harden the rubber seal making it non-
functional.
The rubber seal should be replaced any time it becomes stiff, as this
will interfere with its function.
3.
Recharge the batteries if the total hours used is approaching 8 or more.
4.
Never
leave your
AQ1B-Compact
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. This warning also applies to Aquapulse accessories such as loops,
probes, and bonephones/headphones.
5.
The electronic unit is sealed and pressure tested in the factory, no attempt should
be made to access the electronics. If any servicing is required, contact your
supplier who will advise you where to send the unit. If you ever notice any of the
screws becoming loose on the control unit, they should be tightened immediately.
Battery Care & Checking Battery Performance/Status
The AQ1B-Compact internal battery pack is an 8-cell NiMH series pack giving a
capacity of approximately 2700mA/Hrs. This capacity relates to an operational period
of approximately 10 hours from full charge. Note: self-discharge occurs naturally in a
rechargeable battery. During inactivity this self-discharge causes the battery to slowly
discharge itself over a period of months.
Checking Battery Pack Voltage
To test whether or not your battery pack is charged, you may use the following test,
which requires a DC voltmeter. A digital voltmeter type is preferred since this
measurement of voltage needs to be made to a resolution of tenths of a volt
1.
With nothing connected to the detector, turn the detector ON (one click
clockwise).
2.
With the detector placed so the printing on the top label is in normal
orientation, place the positive lead of the voltmeter on the TOP pin of the
Loop connector (See diagram).
3.
Place the negative lead of the voltmeter on the TOP pin of the Phone/Charge
connector (See diagram).
4.
You should now be able to read the voltage of your battery pack.
5.
A fully charged new battery pack should initially read over 13 volts. This
might decrease slightly as the pack gets older. As the detector is used, the
