4. Verify the current frequency plan configuration. To verify the plan, check the connections between the
J connectors (located on the board and labeled
J1 and J2 ) and the Chan connectors (located on the
diplexer). The Chan connectors are labeled 2421 (Chan 1) and 2462 (Chan 2) for most TRACER 4106
systems and CH1 and CH2 for most TRACER 4206 systems. The following table outlines the
connections for Plan A and B.

5. Using the torque wrench, disconnect both cables from the Chan connectors on the diplexer. Do not
attempt to disconnect the J connectors (located on the board) as this will cause damage. Click

6. Carefully flex the cables to swap the connections. Be careful with the RF cables, making sure that the
minimum bend radius of the cable is greater than 0.75"; bends and loops smaller than a quarter will
cause the RF cable to break. Use the wiring guidelines in Figure 3 and Figure 4 on page 4 for help with
wire placement.

Allowing the RF cables to sit on the processor and radio boards (green) could cause
