Flashing Rate:
The unit recharges quickly, as indicated by the READY light on the control panel. A
quick series of flashes can be obtained within the limits of the recharge time. Continuous
rapid flashing, however, can overheat and damage the flashtube and internal parts. The
maximum recommended rate of flashing depends on the power level being used and the
amount of operation time. Use the following chart to serve as a guide for the maximum
rate to use in your situation.
