1.4. LIGHT AND HEALTH Our daily functioning varies in line with the 24 hours of the day. This circadian (from circa = about, dies = day) variation is caused by our internal biological clock, which gets its timing cues from the external light-dark cycle. A wellsynchronized biological clock helps regulate our mood, sleep, energy, appetite and digestion and helps ensure our well-being.
2. USE OF THE DEVICE 2.1. BASIC USE The device emits UV-free, blue-enriched white light through the ear canals to the light-sensitive regions of the brain. Most people benefit from the default bright light settings of the device (see ”Technical Information”) when applied in the morning. Good timing of exposure to Valkee bright light is essential for reaching the best results. The best time to use your device depends on the intended purpose of use.
2.2. SUGGESTED USE 4. 5. Enjoy the Valkee bright light until the device switches off automatically after 12 minutes (by default). Clean the earplugs regularly. NOTE: You can interrupt the session by pressing the power button again. If you turn on the device again within 10 seconds, you can resume the session from the point of interruption. NOTE: If you press the power button to start the device without first connecting the Ledset, the device gives an error signal (four beeps and four flashes).
withdrawal, decreased physical activity, fatigue, cravings for foods that are high in carbohydrates, and weight gain, use the device on a regular basis in the morning within two hours after waking up at the same time each day. If your seasonal mood swings are more severe and you are suffering from depression, or if you currently are on medication for depression, consult your physician and use light therapy only under supervision. 44 2.3.
2.4. ADJUSTMENT OF THE LIGHT SETTINGS Connect the USB cable to the main unit and the computer’s USB port.

Recharge your device when the bottom-most indicator light is flashing. Before you consider changing the default settings, try the bright light at a different time of day: not everyone benefits from morning light exposure.
On first use, the session starts with the default bright-light settings (see “Technical Information”). The default settings can be adjusted in the following manner: 1. 2. 3. 46 Turn off the device.
