There are two possible reasons why your BIOSENSE™ device may occasionally ask you to Try Again.
- If the device was not able to fully prepare the sensor to receive a breath sample, you will see a Try Again message. After this message, BIOSENSE™ will perform additional sensor preparation steps.
- If the device does not detect a breath at the Blow screen, you will see a Try Again message. This can happen if you blow too gently or if you simply forget to blow. After the Try Again message, BIOSENSE™ will revert back to the Press Start screen where you can attempt another breath sample.
- The alcohol in the hand sanitizer and the acetone in the nail polish remover can interfere with the BIOSENSE™ sensor and trigger a Try Again message. You should avoid using the BIOSENSE™ device immediately after using these products.
