The clip is rigid; please use care when installing the battery. 3 Step 3 Locate the Elevator Modules (sold separately), identified by the four card-edge connections. 3 Step 4 Identify each Elevator Module as either Primary Elevator (white connections) or Secondary Elevator (black connections). 3 Step 5 Plug primary connections side of the TWR-FRAM board to the Primary Elevator. Place the TWR-FRAM in top position of the Elevator (see inset photo). This provides easy access to the jumper pins. 3 Step 6 Identify the primary and secondary card edges of the Processor Module (TWR-K53N512 or similar device) and any additional modules you add to your tower system. 3 Step 7 Plug the primary card edge of each module into the Primary (functional) Elevator. 3 Step 8 Place the Secondary Elevator module onto the secondary card edges. 3 Step 9 Follow instructions in the Quick Start Guide.
