REGULAR USE
Your BACtrack Mobile is a sensitive instrument. Unlike other
electronic devices, your breathalyzer shouldn’t be ignored for
long periods of time. The sensor inside it is delicate and can dry
out if left unused for too long. In order to keep it in good working
condition, we recommend that you blow into it at least once a
month, even if you don’t plan on using it. Breathing into the unit
regularly keeps the sensor in good working order.
Your BACtrack Mobile is rechargeable. You may recharge the
unit with the micro-USB cable included or any micro-USD cable.
When the back and front lights of the BACtrack Mobile are pulsing
slowly, the battery is charging; when the lights are on very dimly,
the battery is fully charged.
