Now place the smaXtec pH Plus Bolus into the container sensor head first and
gently shake it. Calibration of the smaXtec pH Plus Bolus takes at least 5
minutes. During this time the LED starts to repeatedly flash three times in
succession.

period of 30 minutes.
If calibration fails, the LED flashes very rapidly (every 100 milliseconds) for a
period of 30 minutes. If this is the case, please contact customer support.
