TR-45 OPERATIONS

This release unit is deployed underwater and contains a micro computer and batteries and holds a replaceable release link with a screw on retainer cap.  It is programmed to the time-until-release (TUR) desired by electrical contact with the contacts on a programmer (TRP-45C) before deployment underwater.  Release accuracy is +/-2 minute per month.  After time is up and release erosion initiates it takes typically another 10 to 20 minutes for the link erosion to complete with link LK-40 (15 to 30 minutes for link LK-80). (Note: This release works in ocean water and typical bay water.  It will not work in fresh water since the electrolytic erosion will not occur at a fast enough rate).
