Visual and Audible Start-up Indicators
When powered on, the cartridge triggers a start-up light and
sound sequence to verify indicator functionality before gas
sampling begins.
LEDs illuminate in sequence or display a full activation pattern.
Audible alerts sound briefly to confirm speaker operation.
Device banners or status screens indicate start-up progress.
In some cases, visual indicators may be briefly suppressed during start-up, with only audio feedback active. If expected lights or sounds fail to activate, a start-up fault is triggered.
