The Model 99XXX, 98XXX, 92XXX and 95XXX strobes have a field replaceable Xenon flashtube. (See parts list and exploded view for
part numbers) The flashtube snap mounts onto the printed circuit board. Care should be taken to ensure that the tube holder guide pins
are inserted into the printed circuit board and that the base of
the tube holder is flush with the printed circuit board. Do not remove the circuit board from the base. Service the unit in dry locations.
CAUTION: Unit contains high voltages and high temperatures, disconnect from power and wait 10 minutes before servicing.
