5.1 Dangers and warnings

Datawell distinguishes dangers, threatening your life and warnings, threatening your equipment.

Below you find a summary of dangers and warnings related to the present product.

5.1.1 Dangers

• Never deploy the anchor weight first, always deploy the buoy first followed by the

mooring line, and finally deploy the anchor weight.

• Never stand within loops in the mooring line, never stand between mooring and the ship

board. Lines may pull you overboard.

• Elongated rubber cords may represent considerable elastic energy, do not stand in line

with or near tense rubber cords. Snapping lines may cause injury.

• Prevent the batteries from being short-circuited. Despite the low voltage large currents

may flow.

• While transporting the buoy either by car or by boat, tie it down firmly. A buoy moving

uncontrolled is dangerous.

• A reversed battery in a series of cells produces hydrogen gas which constitutes a risk

when servicing the Waverider. Strictly observe the battery replacement procedure in

section 5.10. Ingression of water can also lead to gas formation through electrolysis.

Handle your buoy with care. Delay manipulating electrical connections and avoid

sparking, smoking or open fire until you have flushed the battery compartment with

fresh air.

5.1.2 Warnings

• Do not spin your WR-SG or DWR-MkIII buoy more than 10 turns at once or faster than

1 turn/10 s. This may damage the motion sensor inside. Apply an anti-spin triangle if

you expect vessels to graze along or against your buoy.

• Do not expose your WR-SG or DWR-MkIII buoy to temperatures below −5 ºC for

longer periods, the fluid in the sensor could be permanently altered.

• Do not insert magnetic materials in the DWR-MkIII buoy as this will affect the

magnetic compass readings. Use original Datawell parts.

• Should the US Department of Defence decide to restore Selective Availability (SA),

this will render the current DWR-G buoy not-usable. As soon as SA is switched off

again the DWR-G will recover directly.

• Safeguard the GPS antenna from collisions, paint and dirt. GPS signals are shielded by

certain types of paint, dirt, etc.

• Protect the rubber cords from being cut, leave them in their blue plastic containers

whenever this is possible.

• Use of non-original mooring line parts may cause galvanic corrosion, early wear, etc.

and may result in disruption of the mooring line and consequential buoy loss.

• Close the hatchcover whenever the buoy is not in use. Otherwise the bags of drying

agent inside the buoy will take up moisture and become saturated. Particularly for a

cold buoy (out of the water) placed in a humid environment saturation will set in very

fast.

• Avoid corrosion of your stainless steel buoy. Apply anodes.

• Always cover unused option ports with a blind flange and rubber sealing ring.

• Prolonged use of the Argos satellite communication unit without an Argos antenna may

damage the unit.
