2.5 OPERATIONAL CHECK

To verify that the basic functions of the unit are operational, it is recommended that the following check-out procedure be followed prior to final system integration. If there are any questions regarding performing the indicated operations, refer to Section 3-3.

2.5.1 Setup

Connect the unit to a primary power source and turn on the power switch at the front of the unit. Verify that the power led is illuminated. If the power led is not illuminated, check the power cord and fuse. A spare 3.15 A fuse is provided inside the power connector.

Switch the primary power off and connect the IF out, LB in, IF in and the LB out at the rear of the chassis to J3, J4, J9 and J10 respectively. Re-establish the primary source of power. The Front display will light and status will be displayed.
