The prime power switch is mounted behind the front panel. To access the
switch, loosen the three front panel thumb screws, slide the front panel
out from the chassis, and then drop down the panel.
Prior to turning on power to the unit, check to ensure that installation is
complete, and verify that the LBC‐4000 is connected to the proper prime
power source, RF Input, and RF Output.
Switch on the unit and verify the cooling fan is operational, the LED
indicators illuminate as expected, and the Vacuum Fluorescent Display is
readable.
