Sure thing! First, ensure the power supply is stable and within the rated range for the E70-R. Sometimes fluctuations can cause irregularities in flashing patterns. Next, check the wiring connections to ensure there are no loose or damaged wires. If everything seems intact, try resetting the device by briefly disconnecting and then reconnecting the power. If the issue persists, it might be a fault with the strobe itself, and you may need to replace it. If you’re still under warranty, contact Wheelock’s support for further assistance.
