• COROS A2 Charging Adapter (charges COROS NOMAD when used with any standard USB-C cable - click here for details) 

Setting up your new COROS NOMAD only takes a few quick steps.

1. First, download the COROS app from the iOS or Google Play store and create an account.
2. If COROS NOMAD is not already powered on, hold the Back/Lap Button (the lower orange button) for 2-3 seconds or until the watch turns on.
3. Select your desired language.
4. Open the COROS app to the Profile Page (4th tab on the bottom).
5. Select “Add New Device”.
6. Position COROS NOMAD underneath your phone camera, and scan the QR code on the watch face. You can also choose the option below the scanner to manually pair via Bluetooth.
7. You will be guided through a setup process in the app to customize your watch settings, wearing hand, notifications, and more. These settings can also be adjusted from the Profile page in the app at any time.

When you first receive your COROS watch, it will be set as default to “Scroll to Unlock” to prevent any accidental starts/cancellations of activities, etc. To unlock your watch, scroll the dial consistently in one direction until the display unlocks.

To change the Auto-Lock setting, press and hold the Back button to open the Toolbox menu. Scroll to Settings → More Settings → Auto-Lock.

COROS NOMAD comes with a COROS charging adapter that works with any standard USB-C cable.

To charge your COROS NOMAD, first remove the charging adapter from the silicone case by gently pulling down on one end of the silicone case until the edge of the adapter releases. Then use your fingers to gently pull the adapter out of the silicone case.

Locate the charging port on the back of COROS NOMAD. The metal pins on the charging adapter fit snugly into the charging port. Plug in the adapter to COROS NOMAD until it snaps into place. The adapter will lie flush against the back of the watch.

Next, plug in a standard USB-C cable to the other end of the charging adapter. Once your USB-C cable is connected to power, your COROS NOMAD will begin charging.

* COROS watches support charging during workouts. Feel free to charge your COROS NOMAD in the middle of the workout recording. Charging will not interfere, stop, or restart your ongoing workouts.

To ensure that your watch can gather the most accurate data possible, here are a few best practice tips to follow. 

• Wear the watch tightly, but not so tight as to cut off circulation. It should fit snug and not slide around with movement. 
• Leave a 1cm gap between your wrist bone and the watch. The higher the watch is above the wrist bone, the more flush the surface of your skin, and the less likely the sensor is to be impacted by flexion in the wrist. 
• Keep your hands warm. The OHR signal comes from your blood reflection. So, the more blood flow you have, the better signal your watch will receive. The weather doesn’t need to be freezing to impact your OHR accuracy. As long as your hands feel cold, your blood flow is reduced significantly. The best way to solve this is to try and keep the area where your watch is located on your wrist warm.. Another suggestion is always warm up your body (and your hands) before starting your workout in the winter. 
• Wait for your watch to display a stable HR reading. Just like your body, your OHR sensor requires some warm-up too. It’s recommended to stay on the “Start” page and wait a little longer so the watch can filter some noise by itself. Our watches also provide an alert beep to let you know when it’s ready to go ( if sounds are turned off, you will see a heart symbol that will be solid and steady when ready) 
• Select the proper training mode. The regular running, cycling, and swimming algorithms are not specifically built for tracking rapid changes in heart rate. When you train with intervals, please select the Interval Training mode under Run mode for enhanced heart rate tracking sensitivity.
