Pair New Device Note: In the Apple App store make sure to download the Soberlink Connect App not the SLBLUE App. 4 Preparing to Submit a Test This document, and any other provided training material, should be fully understood by the user before submitting a test. To ensure proper device function keep it fully charged. To avoid damage or injury caused by the product only use accessories provided by the manufacturer. Find an area free from alcohol, cleaners, solvent vapors, and smoke before submitting a test. Use the Device within the operating temperature range (32°F -113°F). Breathe normally before submitting a test. Remove sunglasses, hats, or other objects covering the face. Wait 20 minutes after eating, drinking, or smoking before submitting a test. Failure to wait may result in inaccurate test results. Rinsing out the mouth with water does not act as a substitute for the 20-minute waiting period. 12 6 5 4 3 2 1 9 8 7 10 11 2 4 3 2 1 WAIT 20 MINUTES NO EATING NO DRINKING NO SMOKING The Device must be activated before submitting a test. To activate call Soberlink at 714-975-7200 or contact your Treatment Provider. 5 Submitting a Test Open the Soberlink Connect App. The App should remain open for the duration of testing. Press the Power button to turn on the Soberlink Device. Follow the prompts on the App, and wait for the green light to flash before submitting a test. When prompted to blow, look directly into the camera, breathe in deeply and deliver a firm, continuous breath for 4 seconds. The Device will click when the test is complete. Note: Do not hold the mouthpiece or obstruct the camera. The test results will take approximately 30 seconds to display on the App and send to the Sober Sky Web Portal. Once the test has successfully sent, close the App. Note: After a positive BAC (Breath Alcohol Concentration) is received, wait 15 minutes before submitting another test. 6 Client Text Notifications Once a schedule is enabled on the Sober Sky Web Portal, Soberlink’s automated system will send text message reminders directly to the Client’s phone. Reminder texts are sent before and during the test window. Missed notification after test window closes Notification of retesting requirement 30574 REMINDER TEXT: This is your 8:00 AM PST test reminder. 30574 MISSED TEST: You have missed 1 or more tests. Send a test now. 30574 RETEST REQUIRED: A test is required at 8:18 AM PST. Note: Upon entry of a mobile number on the Sober Sky Web Portal, the Client will receive a text message and must respond as instructed in order to Opt-in to notifications. 30574 You have requested to receive Soberlink Alerts.

We declare that CETECOM Inc. is allowed to forward all information related to the approval project to the Federal Communications Commission and discuss any issues concerning the approval application. The applicant must certify that neither the applicant nor any party to the application is subject to a denial of Federal benefits, that include FCC benefits, pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. § 862 because of a conviction for possession or distribution of a controlled substance. See 47 CFR 1.2002(b) for the definition of a "party" for these purposes. Does the applicant or authorized agent so certify? ☒ Yes I certify that I am authorized to sign this application. All of the statements herein and the exhibits attached hereto, are true and correct to the best of my knowledge and belief. In accepting a Grant of Equipment Authorization as a result of the representations made in this application, the applicant is responsible for (1) labeling the equipment with the exact FCC ID specified in this application, (2) compliance statement labeling pursuant to the applicable rules, and (3) compliance of the equipment with the applicable technical rules. If the applicant is not the actual manufacturer of the equipment, appropriate arrangements have been made with the manufacturer to ensure that production units of this equipment will continue to comply with the FCC's technical requirements.
