A two way radio used in a converta-com equipment has 3 variable battery pack sizes, namely, 500mAH, 9OOmAH and 950mAH.

   The radio in use can be located in a pocket properly using a stopper at the base of the radio extending from side to side. This stopper cannot be a fixed one as different battery sizes will change the datum of the radio with respect to the front of the radio which is fixed in the CVC. This will not allow proper charging as the battery contacts on the radio are a fix distance away from the base. This means to say that the stopper has to be flexible in a sense that should allow the user the ability to move it to designated places in the pocket to accommodate different radio sizes (Fig. 3). This will allow different radio sizes to be used without need to have specific pockets for specific radio sizes.

   The solution lies in catering holes on the side of the pocket at designated places to accommodate a rod that runs across without protruding out from the sides to permit the pocket movement. The next is to allow easy insertion or withdrawal of the rod without need for complicated tools. The criteria will be that the stopper an take up the impact upon radio insertion and the rod once inserted stays in place. Keyways along the sides of the rod allows the rod to be dropped into place through the opening at the side of the pocket. Using a com- mon tweezer, deflect the two circular catches using the steps provided at the tips of the catches (See fig. 1). Insert the rod fully until the catches sit flat into the sunken portion of this opening (See fig. 2). At this stage the catches are already in adeflected position, sitting inside the...
