Alcolizer Troubleshooting Guide (WM4)

Alcolizer – “Off-Button” Reset

If an Alcolizer experiences any issue or is not scrolling its on-screen messages every 10 seconds, is not displaying "Self Test" during an anonymous BAC Self Test or displaying any user's Name & ID Number during login, then it may require an “Off-Button” reset.
NOTE: Disconnecting mains power, or switching mains power off, is not the correct reset procedure, and often this will not have the desired outcome. Please ensure that the steps below are followed.

1 - Unlock & open the Alcolizer.

2 - Ensure that the COM cable is securely connected (pictured below) -

3 - Check that the gas bottle has been opened, by turning the value towards you -
(A few turns, or simply checking the position is fine, the valve does not require multiple turns to be open).

4 - Locate this group of 6 small buttons, then press the one at the bottom right of the group, marked as " OFF " (pictured below) -

The device should begin to shut down. This can be confirmed via the display panel on the front, indicating 3 "loading" style circles, which will fill as the shutdown progresses.
NOTE: Please leave the Alcolizer plugged in & switched on at mains power, during this.

(4a - If the device does not begin to shut down after pressing the button once, hold the "OFF" button down instead, for up to 1 minute.
4b - If holding the "OFF" button has no impact either, then please power the device off / or unplug it at the mains connection, wait 5 minutes, then plug it back in).

5 - Once the display has switched off, & is black/blank, wait 5 minutes.
NOTE: Please leave the Alcolizer plugged in & switched on at mains power, during this.

6 - Press this same "OFF" button again, to begin the start-up process.

7 - Once the Alcolizer has finished starting up, it will be ready for use. (An automated calibration may take place).
