CARE AND MAINTENANCE
Proper care of your Aquapulse 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,
wash down with clean fresh water.
2.
Dry the detector paying particular attention to the area around the plugs.
Clear any excess water by blowing.
3.
Recharge the batteries if the total hours used is approaching 10.
4.
Never leave your Aquapulse 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.
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.
BATTERY CARE & CHECKING BATTERY PERFORMANCE/STATUS
The AQ1B internal battery pack is a 7-cell series pack giving a capacity of
approximately 2500mA/Hrs. This capacity relates to an operational period of between
10 and 12 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. Nicad batteries can develop a "memory"
effect through partial charge/discharge cycles; this effect will reduce the effective
capacity available. To maintain maximum performance it is important to regularly
discharge the battery completely followed immediately by a full re-charge.
Periodically, to ensure adequate operational battery duration, or to confirm the status
of your battery, the following checks and procedure should be carried out.
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 is preferred since these voltages
are low and measurement needs to be made in the tenths of a volt resolution.
1.
With nothing connected to the detector, turn the detector ON.
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.
