Handset Unit LEDS

LED 1 indicates the battery charge level: 

• Green:  The battery is fully charged.
• Flashing green:  Battery charging.
• Yellow:  Battery half charged.
• Red:  Battery discharged. In the event of a red indication, place the Alcohol Analyzing Start Inhibitor in the charging cradle or connect the power cable from the glove compartment.

LED 2 indicates the result of the breath test. 

• Green:  Approved breath sample (less than 0.1 blood alcohol content). A message indicating an approved breath test appears in the Driver information module (DIM) and the vehicle can be started. If a new start attempt is made within 30 minutes, the vehicle can be started without a new breath test having to be performed. If this is possible a message appears in the Driver information module (DIM).
• Yellow:  The breath sample has a high alcohol content (0.1 - the country's statutory blood alcohol content limit). A message appears in the driver information module (DIM) and the vehicle can be started, but Volvo recommends waiting and taking another breath test later.
• Red:  The breath test has not been approved (higher than the country's statutory blood alcohol content limit). The vehicle cannot be started without activating the BYPASS function.

LED 3 indicates whether the device is ready for a breath test: 

• Green:  The Alcohol Analyzing Start Inhibitor is ready for a breath test to be taken.
• Flashing yellow:  The device prepares itself by reading the temperature, testing the pump and heating up the fuel cell. This can take longer at colder temperatures.
• Red:  The test has failed. This may be due to moisture in the Alcohol Analyzing Start Inhibitor or that the inhibitor has been affected by a radio transmitter, for example.
