This App was designed to assist Guardian Alcohol Interlock users when they are out and about in their car. The App also has a support link to send enquiries through which is handy if you are out and about and can’t make a phone call. The App allows you to find the nearest service centre for your servicing, downloading and calibration needs and has a helpful search option for any error codes that the alcohol interlock displays. This search tells you what is causing the error and what you need to do when that error appears. The App has a copy of the user manual for the WR3 model and LR model alcohol interlock to refer to.
