Using an iBreath Alcohol BreathAlyzer

To use the iBreath first make sure that it is drawing power. Though the iBreath doesn’t have its own batteries, there are several ways to power the device:

Plugging it into an iPod or an iPhone.
Using a USB cord for connecting the device to a computer.
Connect the iBreath to the vehicle using the provided 12-volt car plug.

To use the Breathalyzer function, unfold the blow wand from the device. Then press the ENT button on the device and a 10-second countdown begins. During this time, the tiny heating element inside the iBreath warms the gas sensor tin dioxide membrane to the appropriate temperature. Once the sensor is ready blow a steady stream of air into the wand for about 10 seconds. The semiconductor chip reacts to any alcohol in your breath and measures the resulting change in resistance. The LED screen displays the estimated BAC. You can repeat the test by setting a timer on the iBreath that will remind you of when to take the test again.

If you want to use the FM transmitter, just push the Mode button on the device. The device has two tuning buttons that help you adjust the frequency of the transmitter so as to get the best result. Using a combination of these buttons and the ENT button allows you to set the radio frequency. Once an available channel is found, pressing the lock button would keep the device tuned to that frequency even if any other button is accidentally hit.

Using devices like iBreath prevents you from making serious mistakes since driving under the influence of alcohol is both dangerous and illogical.
