4. For re-arming procedure of AR 601 AP, AR 661 CS and AR 661 DS, insert a release ring at
the right place (take care of the good position of the hook) and transmit a release command. The
motor runs a quarter turn. The release ring should be locked in the hook.
For re-arming procedure of AR 661 B1S and AR 661 B2S, first remove the locking shaft (ref.
910 1662) then fit the release ring. Correctly close the hooks N° 1 and 2, then fit the locking
shaft (ref. 910 1662). Check the locking of the release ring and the good condition of the hooks.
5. Program the "interrogate/ranging" code on the telecommand transmitter. Transmit the
command code. Check that the AR unit has transmitted an acoustic pulse at the end of the
command.
In the air, the distance displayed on the telecommand unit is not the real distance between the
AR unit and the telecommand unit.
6. Do not deploy an AR unit unless it has successfully operated in each of its modes.
6.2. Mooring Line Considerations
The AR 6X1 Acoustic Release may be inserted in the mooring line just below the floats or
oceanographic equipment to recover.
Take care that the transducer head is free of obstruction.
AR unit should be oriented the way towards the surface.
Special attention should be given to the following considerations:
. No dissimilar metals should be used in the connections of the mooring line unless perfectly
insulated by neutral material such as Delron or Nylon.
. A proper sized release ring should always be used.
. It is recommended to separate the AR unit from the anchor (dead weight) by a line of 3 to 5
meters long. This separation should be a negative buoyant line to prevent this line to wind
around the AR body.
. If the sea bottom topography is not flat, do not hesitate to increase length of the line between
AR unit and anchor as necessary.
. The buoyancy package for recovering the AR should be a 2 or 3 to one ratio of positive
buoyancy versus the AR weight in water.
. The dead weight for anchoring the mooring line should be dimensioned to prevent drifting
due to tidal or current actions.
. The anchor weight in water should be at least 3 or 5 times the positive buoyancy fitted on the
AR 6X1 line.
