2A7ZK-LBLFF01Lumos Firefly

*For optimal charging, charge in ambient temperatures of <=30°C. If charging gets too hot, Firefly will temporarily stop charging to protect itself from overheating. Charging will automatically resume once it has cooled down sufficiently. The Lumos Firefly has a small LED indicator to convey different information. Please note the colours below and the corresponding message. Red LED light - Firefly is charging. Green LED light - Firefly is fully charged. Yellow LED light - Firefly has temporarily paused charging to allow it to charge within acceptable operating temperatures*. FIREFLY CHARGING INDICATORS LED indicator Rear of Firefly Sticker CHARGING FIREFLY For more information, visit firefly.lumoshelmet.co Syncing all of your Firefly lights is as simple as double-tapping the power button. Any surrounding Firefly lights will then sync to the same pattern. When the battery is low, place your Firefly into the Charging Cradle and connect it to a power source. A red LED light should appear indicating it’s charging. Firefly is fully charged when the red LED light on Firefly turns green. It takes roughly 5 hours for a full charge. Note: Firefly is Qi-compatible and can also be charged with other Qi wireless chargers.

FIREFLY KEY COMMANDS For more information, visit firefly.lumoshelmet.co DISCOVER MORE FEATURES For more information, visit firefly.lumoshelmet.co Seatpost padding allows you to mount Firefly at an angle. It is most suited for use on seatposts or other positions that require angled mounting, like forks. Low profile padding is flat and suited for most other mounting positions (ie: handlebar) Slot the protruding ends into the designated holes located below the universal mount When riding with Firefly, it is important to get the right angle to ensure the most optimal riding position. That's why we've included multiple sets of padding to suit different needs. MOUNTING PADDING For more information, visit firefly.lumoshelmet.co Download the Lumos App to unlock the full potential of Firefly UNLOCK YOUR ECOSYSTEM For more information, visit firefly.lumoshelmet.coFor more information, visit firefly.lumoshelmet.co All Lumos Firefly come with a set of navigational stickers to tell all your Firefly lights apart. When using multiple Firefly lights in your setup, place the sticker corresponding to its profile in the indentation on the rear of Firefly. IDENTIFY YOUR FIREFLY AT A GLANCE For more information, visit firefly.lumoshelmet.co Silicone strap Velcro strap The velcro strap provided can be used to mount the Firefly in more unusual places that cannot be achieved with the silicone straps, such as around an arm or a non-smart helmet. Attach the appropriate padding to the mount. To mount the Universal Mount, secure the silicone strap into one of the hooks on the mount. Pull it around your desired mounting surface and secure the strap in the opposite hook. To use the velcro strap, feed it through the two slots in the base of the Universal Mount as shown. Ensure that the Lumos logo is facing down when you feed the velcro through the hole. Wrap the velcro around the mounting feature you are trying to mount to. In some instances, you may need to wrap the velcro around multiple times. Ensure a tight fit to reduce unwanted vibrations. SILICONE STRAP MOUNTING VELCRO STRAP MOUNTING For more information, visit firefly.lumoshelmet.coFor more information, visit firefly.lumoshelmet.co Align to opening Push Push To use the mount clips, simply insert them into the side of the Universal Mount as shown. You'll need to install both clips for this to work as intended. Now when you place a Firefly into the Universal Mount, you should be able to feel the clips engage. You may need to push the Firefly in to secure it fully. To remove Firefly, press both clips at the same time. Feel free to keep the clips attached if you prefer to do so. The Universal Mount was designed to work both with and without the clips. For more information, visit firefly.lumoshelmet.co We've designed mounting clips specifically to give extra peace of mind to prevent Firefly from falling out of its base. Note: under normal cycling conditions and even fairly rough terrain, we never encountered an issue with Firefly falling out. WORRIED THAT FIREFLY WILL FALL OUT EVEN WITH THE STRONG MAGNETS?

FCC ID: 2A7ZK-LBLFF01 RF exposure evaluation §2.1093 Radiofrequency radiation exposure evaluation: Portable Devices. According to§15.247(i) and§1.1307b(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the commission’s guidance. The 1-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR, where  f(GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation  When the minimum test separation distance is < 5 mm, a distance of 5 mm according is applied to determine SAR test exclusion.  The result is rounded to one decimal place for comparison  GFSK Modulation Frequency (GHz) Max.
