Compared to the standard FR300, the FR300 ANT+ version connects with Garmin bike computers via ANT+ technology, allowing riders to conveniently switch light modes directly from their Garmin device.
Note:
FR300 ANT+ is exclusively compatible with Garmin bike computers through ANT+ connection (the bike computer itself must support ANT+ technology).
DO NOT charge your mobile phone or other devices with the light, otherwise it might damage the light and void the warranty;
DO NOT charge or discharge the light when raining.
