General guidelines

Operational time and service life of the sensor’s NiCd battery

depends on proper use and regular charging. Observe the

following precautions, as these will have an influence on the

battery performance:

• Observe the char ging temperatures.

• Charge sensors regular ly. Avoid draining the sensor battery

completely before charging.

• Charge the sensor battery before storage, and at three-month

intervals under long-term storage.

• Operational life may be initially reduced after long-term

storage or charging for a long time.

• Sensors are not damaged by being left attached to a charger

for several days. However, do not store the sensor for

extended periods under charge.

• We recommend that a wooden box is made to keep the sensor

in a secure place during charging and storage. Make openings

in the bottom to drain for sea water.

Battery depleted frequently

If the charger lamp is illuminated, but the sensor lamp does not

flash every four seconds, the battery is not being charged

properly. Most likely, this is because the sensor was not

switched off when the charger was connected.

To correct, charge the sensor for ten minutes, then disconnect

the alligator clips. Use a small wire, and make contact between

the water switch sensor and one of the fastening lugs. This will

cause the sensor to flash its start-up code. If not, wash the sensor

in fresh water to disengage the water switch.
