Many of the features found on bigger and heavier machines can be found in the small, lightweight Transcend Auto. This is an Auto-Adjusting machine with a pressure relief comfort feature that will change pressure on a breath by breath basis during use.

    • EZEX Pressure Relief
    • Small & Lightweight
    • Quiet Operation

    Auto-Adjusting Technology

    The Transcend Auto adds auto-adjusting technology to the popular design of the Transcend line of machines. A person's pressure needs can fluctuate during sleep as a result of mask leaks, position shifts and apneas. The Transcend Auto will change the air output to only give the needed amount of pressure for each breath, making for therapy that is comfortable and effective. If desired, the machine can be set to in a single pressure mode and act as a CPAP machine.

    EZEX Pressure Relief

    To make therapy even more comfortable, EZEX pressure relief is featured on the Transcend Auto. EZEX pressure relief allows for the pressure to drop a set amount when breathing out, resulting in more comfortable exhalation. The EZEX feature can be set at one of four settings: 0 (No Relief), 1 (1 cm H2O of relief), 2 (2 cm H2O of relief) and 3 (3 cm H2O of relief).

    Small, Lightweight & Quiet

    The Transcend machines are known for their small size and light weight, and this holds true with the Transcend Auto. With the machine itself weighing less than a pound, it can easily be packed and carried during travel. The small footprint of the Transcend Auto leaves a nightstand open to other nighttime accessories such as alarm clocks or lamps that may have been sacrificed to bigger and bulkier machines that demand more space. Making its presence even more discreet while in use, the Transcend Auto comes in at a very quiet level of 26.6 dB.

    Flexible Power Options

    The Transcend Auto keeps travel in mind with the inclusion of a power supply which has international plug adapters for use in many countries including the United States, United Kingdom, European Union, and Australia and New Zealand. Add in the optional Transcend Multi-Night Battery and the Transcend Auto Travel CPAP is ready to provide a restful night of sleep almost anywhere.

    Easy Maintenance Filter

    The filter frame on the Transcend Auto can be removed with the push of a single button. Once the frame is removed, the separate filter can then be washed or changed as needed. The filter is a foam strip that should be rinsed weekly and allowed to air dry before reinserting. The filter frame of the Transcend Auto CPAP Machine is dark gray.

    Email Capable Data Tracking

    The Transcend Auto Travel CPAP machine with EZEX holds up to 13 months of data including:

    • Minimum Therapy Pressure
    • Maximum Therapy Pressure
    • Starting Therapy Pressure
    • AHI (Apnea Hypopnea Index)
    • Leak Detection
    • Total Therapy Hours
    • Number of Therapy Sessions: 8 Hrs (default); 6 Hrs; 4 Hrs
    • Total Hours the Blower Has Operated

    miniCPAP Warranty Tip

    Please Note: This manufacturer provides refurbished units as warranty replacements. To provide Somnetics with feedback on this policy, please use this email or call 877-621-9626.

    Transcend Auto miniCPAP™ Machine with EZEX Product Notes:

    • Required Hose Adapter Included: The Transcend Universal Hose Adapter is required to connect the long hose to the Transcend Auto machine. Both the hose adapter and long hose are included with the machine purchase.

    • Hose Adapter Updated: In mid-2014 the manufacturer made an update to the hose adapter included with the Transcend line of machines. The updated adapter has a hard support cuff surrounding the silicone machine connection. The swivel end of the adapter connects to the long hose. The non-swivel end of the adapter connects to the hose port on the machine.

    • Universal Hose Adapter May Be Attached To Hose: The Transcend Auto machine includes the Universal Hose Adapter and a 6 foot hose. The manufacturer may package the Transcend Auto with the universal hose adapter already connected to the long hose. If the adapter is inserted onto the machine, the connection may be very tight but the two pieces are NOT permanently attached. They can be separated. To remove the white adapter, leverage it against the rubber hose cuff and twist it off.

    • Universal Hose Adapter Not Used with Humidifier: When using the OPTIONAL Transcend Heated Humidifier the Universal Hose Adapter is NOT used. If the Universal Hose Adapter is on the Transcend Auto, remove the hose adapter prior to inserting the machine into the humidifier cradle.

    • USB Cable: The Transcend Auto IS packaged with an USB cable. The machine must be connected to a computer using the cable to change the settings using a 32-bit PC processor. A USB cable with a mini connection on one end and standard connection on the other end can be used for this purpose. offers this option: 3 ft. USB 2.0 Type A Male to Mini B Male Cable.

    • Transcend Software System Compatibility: The software used by the Transcend miniCPAP™ is compatible with Window XP, Windows Vista, Windows 7, Windows 8, and Windows 10 using a 32-bit or 64-bit system. The Transcend software is not compatible with the Apple operating systems. Please Note: If using recent Windows versions, the USB drivers may require updates. It is best to contact the manufacturer of the computer for update instructions.

    • Software Download: The Somnetics Software Revision C for the Transcend machines can be downloaded here: Transcend Software Revision C Download. For more details, refer to the Transcend Software User Manual.

    • Oxygen Use: Though Oxygen can be connected to Transcend miniCPAP devices, the manufacturer recommends that Oxygen not be used with this machine.

    • Available Therapy Pressure Range: The Transcend Auto miniCPAP™ Machine with EZEX has pressure range of 4 to 20 cm H2O . The maximum pressure it can deliver is 20 cmwp. The minimum pressure it can deliver is 4 cmwp.

    • FAA Compliance Letter for Somnetics Transcend: Click Here to View.

    • Adjusting or Single Pressure Settings: The Transcend Auto can be set in either an APAP or CPAP mode. When set to auto adjust it will deliver the best pressure during sleep. When set as a CPAP it will deliver a single pressure during use.

    • Large Leak Response: When a large leak is detected by the Transcend Auto miniCPAP™ Machine with EZEX the machine will quickly ramp up to a high pressure and then shut off. If this occurs, please check to verify that the Transcend Universal Hose Adapter is installed correctly. The hose and pressure line ports on the machine must be fully connected to the Hose Adapter to avoid pressure loss. The pressure line port must be firmly seated into the tear drop shaped area on the adapter. If the issue is not corrected, check to be certain the mask and hose have a secure connection. Further, ensure the mask is adjusted properly to provide a good seal on the face.

    • Power Supply Design: Prior to Fall of 2013, the power supply included with the Transcend line of machines was made of only two parts - the power supply and cord and did not offer the multi-country adapters. The connection to the Transcend machine is unchanged between the two design versions.

    • Filter Frame Design: The Transcend Auto has an updated filter design. It allows the filter media to be replaced without replacing the entire plastic piece. The dark gray base of the Transcend Auto machine is the filter frame. Use the push button to release the filter frame from the bottom of the machine. The washable foam filter media can be changed and the plastic filter frame replaced on the machine. Earlier versions of the Transcend used an air inlet filter which had filter material permanently attached to the plastic frame that was removed with a release latch. The old style filter with release latch and permanently attached foam filter strip will NOT work with the Transcend Auto.

    Filter Installation: The Filter for Transcend machines fits the filter frame in only one orientation due to the shape and curve of the filter and the frame and machine base design.

    1. Remove the filter frame from the bottom of the Transcend machine.
    2. With the machine base facing up, lay the foam side of the filter on the machine base. The curve of the filter will match the curve of the machine base.
    3. Line up the notch on the filter with the tab on the machine base.
    4. The firm backing of the filter will be against the filter frame and the foam portion of the filter will face the machine body.
    5. When properly installed the filter lays flat against the machine base.
    6. Line up the filter frame on the machine and snap back in place.

    Transcend Filter Care: The manufacturer recommends washing the Transcend Filter weekly using a 5% mild liquid detergent and distilled water. Allow the filter to air dry before reinstalling. An example of a mild detergent is Tide Free & Gentle.

    Sound Level Tips

    Although the Transcend Auto miniCPAP has a low decibel rating of 26.6 dBA, some users report a noticeable pitch from the machine's motor, which may be a result of its reduced size. Unlike larger machines, smaller travel CPAPs have less internal room and components to absorb the sound of the motor. To help reduce the sound of the motor, consider adding the Q-Tube In-Line CPAP Muffler Kit to the device.
