attempting to activate a tower boom function,
the function is being cutout by tower boom limit switch. This
function is not permitted at the current boom configuration.
When an audible alarm sounds and the Boom Malfunction
Indicator illuminates steady without a boom function
attempt, the upright is out of alignment.
DISCONTINUE OPERATION IF THE UPRIGHT IS OUT OF ALIGNMENT OR THE BOOM

MAIN BOOM AND TELESCOPE OUT UNTIL THE PLATFORM REACHES THE GROUND. THE
