    By using the USB port on the Transcend 365, you can connect your machine to a computer and access your therapy data. From there, you can use software to view and analyze your therapy data. The Transcend 365 currently does not have a mobile app for viewing data.

    OPTIONAL: Portable Water Filter Kit Turns Tap Water Into Distilled Water

    If ever you're far away from a bottle of distilled water, you'll be covered with the optional portable water filter kit, which is designed to filter all impurities out of tap water so you can use it in the Transcend 365 Auto's humidifier. By having this handy kit, you'll always have the water needed to keep your humidification going, even if you're nowhere near distilled water.

    OPTIONAL: P10 External Battery Can Power Your Humidifier Too

    Are you tired of turning off your humidification whenever you're off-grid, just because you're running on battery power? Now it can! The P10 battery for the Transcend 365 was engineered for your humidifier too, so you can run both while you're traveling and away from a power source.

    Caring for the Transcend 365

    It's strongly recommended to clean the outer casing of the Transcend 365 with a dry cloth weekly, to ensure the optimal functioning and air quality.

    Cleaning the Transcend 365 Humidifier

    Please follow these steps to clean the Transcend 365 humidifier:

    1. Always fill the humidifier with distilled water.
    2. If necessary, clean any residue at the bottom of the tank with mild soap and water or vinegar.
    3. Once you've rinsed the container, be sure to activate drying mode. Drying mode enables the humidifier to rid itself of excess moisture. Press the up and down arrow keys and hold for 3 seconds to turn on drying mode. This will remove all the moisture left on your humidifier tank.
    4. Once drying mode is complete, you can use the humidifier again.

    Humidifier Water Use

    Due to the unique method in which the Transcend 365 provides humidification, it is important that only distilled water be used, or alternatively, water filtered through the Transcend 365 Water Filter Kit. It is vital that the water used be either distilled or filtered through this accessory so that the wicking system does not incur damage and fail.

    Additionally, using tap water can result in unwanted deposits from building up in the bottom of the humidifier tank. These deposits are often hard, chalky, and difficult to clean. They're the minerals and impurities left behind after the tap water evaporates, and are only found in tap or bottled water.

    Distilled water has all of these impurities removed, and will leave no residue at the bottom of the humidifier tank. Distilled water will work better with the special design of the humidifier. It's available by the gallon at grocery stores or from

    Replacing the Filter

    Please follow these steps to remove the filter from the Transcend 365:

    1. Remove the humidifier tank from the bottom of the machine.
    2. Look for the door near the end of the machine. It should open easily.
    3. Open the door, and remove the filter from the compartment.
    4. Replace with a new filter once every 6 months, or when the filter begins to look discolored.


    Do not submerge machine in water or allow to get wet. While it's ok for the humidifier tank to be filled with water, exposing the rest of the machine to water could result in the machine getting damaged or destroyed. The machine isn't waterproof, and no amount of exposure to water is safe.

    Machine Setup Must Be Done by a Professional The Transcend 365 will be set up correctly by before leaving our warehouse, and future adjustments should be made by a doctor or sleep professional. Since the machine is auto-adjusting, it will automatically adapt to your body's pressure needs several times each night. Therefore, you shouldn't need to adjust the pressure yourself.

    Do not use with Oxygen Therapy. While some CPAP machines are compatible with supplemental oxygen devices, the Transcend 365 is not. Attempting to use this machine in conjunction with oxygen therapy can result in injury or death.

    Do not attempt to use the machine above altitudes of 8,000 feet or temperatures below 40 degrees. Use of this device above altitudes of 8,000 feet or in extreme cold, can result in injury and damage the device. Do not attempt.

    Do Not Use Near Antennas or Portable RF Devices These devices can interfere with the inner workings of the Transcend 365 and could result in the machine malfunctioning. Stay at least 12 inches away from any device with an RF transmitter, including cell phones. Please use caution when using around RF transmitters and equipment.

    Do not attempt to sanitize the machine using activated oxygen or ozone. Using a sanitizer on the entire machine can damage the machine and its components. There is no need to sanitize the machine, and a weekly wipedown will do.
