Why is my BX1 / BX2 / BX4 Bluetooth Tap Timer flashing red?

The BX1, BX2 or BX4 Bluetooth Tap Timer will flash red around the manual ON/OFF button if the following problems have occurred:

• Red flashing light: the battery is low and the timer cannot operate
• Red solid light: the battery is flat and the timer will not operate

Please replace the batteries in your BX1, BX2 or BX4 tap timer with 4 x AA Alkaline batteries.
