What if one of the indicators in my pack has got a blue activation window or there is blue in the run-out window, before I’ve pressed the activation button?
If stored under the correct conditions, there is very little risk of auto-activation, but occasionally, this can happen, and the built-in activation window lets you know it. If an indicator has auto-activated before use the activation window will already be showing blue and ON. The blue liquid may also be showing against the time-markers in the run-out window. If this happens, discard the indicator and select another. There is no need to contact us, as we ship a few extra units per hundred anyway.
