Once recording has started, the “REC” light will blink every 5 seconds. The sensor lights on the Sleep Apnea Monitor (SAM) will turn off for a dark and comfortable sleep environment.

Be aware that pressing the power button twice quickly will turn the monitor off.

If you are ever unsure whether the monitor is on, you can press the power button one time and the lights will briefly illuminate to confirm that it is on. The heart-shaped light (Oximetry) should appear solid blue and the remaining lights should appear solid green. After displaying the status for several seconds, the sensor lights will turn off again.
