Starting/Stopping Therapy
1. Connect the Transcend Micro to a power source and allow it to enter Standby Mode.
2. Be sure your mask fits firmly and in place before starting therapy.
3. Press the Power button or breathe normally to engage SleepStart. Therapy will
begin when the blower delivers or ramps to the prescribed therapy pressure.
NOTE: Some masks are configured differently. Due to this variability SleepStart may
not function.
NOTE: If therapy is interrupted by a power failure, the device will automatically
restart therapy once power is restored.
Using the Ramp Function
The Ramp feature lets you acclimate to air flow by starting at a lower pressure and
gradually increasing to the prescribed pressure setting as you fall asleep.
To accelerate the rate of the pressure increase during Ramp mode:
•Hold the Ramp button down until the device reaches a comfortable therapy
pressure.
•When the Ramp button is released, the device will continue in Ramp Mode until it
reaches the prescribed therapy pressure.
•To end Ramp early, hold down the Ramp button until the prescribed therapy
pressure is reached.
•If Ramp is no longer desired, disable it via software. Or disable auto-ramp by
pressing the Ramp button when in standby.
NOTE: To adjust ramp starting pressure or duration see the Transcend Micro
software manual available on the Transcend website (mytranscend.com).

Page 14
Using the EZEX Function
The EZEX function is a feature that decreases therapy pressure on exhalation. This is
designed to provide additional comfort to the user by reducing the amount of resistance
they experience as they exhale.
There are four EZEX settings: OFF, 1, 2 or 3. Each setting progressively increases the
amount of pressure relief from none to maximum.
See the Transcend Micro software manual available on the Transcend website
(mytranscend.com) and follow the steps to change settings.
Ending Therapy
Remove your mask and wait until the device ramps and stops or press the Power button.
Due to different configurations of the air circuit, the device may not shut off upon removal
of your mask. Press the power button to end therapy.
Drying Mode
At the end of each therapy session, it is recommended that the user initiate the Drying
Mode function to dry the attached air hose and accessories.
To initiate Drying Mode:
•Press the Drying Mode button.
•When in Drying Mode, the blower will run at a low speed for 30 minutes.
•During Drying Mode, the Drying Mode LED will continue to glow.
•After 30 minutes, the blower will turn off and the device will enter Standby Mode.
