Prepare your
AlcoMate Prestige. |

Use a flat, sharp tool to
carefully open the top cover. |

Lift the breath tube to
access the sensor module. |

Remove the breath tube.
It should remove easily. |

Carefully raise the sensor module from the body.
Do NOT detach the cable from the body. |

Remove the cable from the slot underneath the sensor
module. |

Prepare a new pre-calibrated sensor module. |

Insert the cable into the new sensor. Make sure
the blue strip is toward the sensor, as shown.
|

Replace the sensor module into its original position. |

Re-attach the breath tube directly on to the sensor.
Make sure the front opening is aligned. |

Re-attach the cover on to the top of the body. It
should snap in fairly easily. |
