The outer light of the Wake Button on the t:slim, t:slim G4, t:slim X2, and t:flex pumps will glow different colors depending on pump status:
- One green blink every 30 seconds indicates the pump is functioning normally.
- Three green blinks every 30 seconds indicate the pump is charging.
- One yellow blink every 30 seconds indicates an alert or reminder condition.
- One red blink every 30 seconds indicates a malfunction or alarm condition.
If the battery is fully discharged, the screen will not power on immediately when connected to a charging source. The LED will blink green every two seconds until there is enough charge to power-on the touchscreen.
