This system provides for apparatus and process in conjunction with long-range wireless communication networks such as paging, cell phone and other networks. The medical device has at least one surface that contains one or more depressions, which are at least partially filled with a soluble material. The tilt and trim device is operative to prevent deformation of and damage to a trim cylinder by suppressing the hydraulic pressure applied to the trim cylinder to be not greater than a specified pressure value even when the outboard motor is rapidly lowered from a tilt range, and a high hydraulic pressure from the tilt cylinder is returned in the direction of the trim cylinder. Holding-down elements are connected to the lower guide rail, wherein the guide brackets have a stop edge and wherein the holding-down elements prevent the cutting belt from lifting off the lower guide rail. The cover is capable of being fitted to the housing in different orientations, and in the cover the electrical contacting arrangement is disposed so as to provide at least two fixed contacting configurations for at least two different power functions alternately assigned to different alignments of the cover. A method for the handling of the explosive includes the steps of providing the modular structure kit, using the kit to assemble a containment structure around the explosive while avoiding obstacles near the explosive, and handling the explosive within the containment structure.
