About this item

• [Battery] Remove the insulation sheet of the pre-installed battery before use; reinstall the battery to switch between speed and cadence mode.
• [Mode] 1 sensor can ONLY select one mode (speed or cadence) at a time. So you need 2 sensors to test both speed and cadence. (1 for speed, 1 for cadence)
• [Device] When using Bluetooth protocol, 1 sensor can ONLY connect to 1 APP or device at the same time; When using ANT+ protocol, you can connect it to multiple devices at once.
• [Connection] When using a smartphone APP, you need to search the sensor in the APP, the search through the Bluetooth setting of the phone system is invalid.
• [Hibernation] The S3+ sensor will automatically enter the sleep state for 1 minute to save power after the sensor is stopped, the sensor will ONLY start sending transmissions after being properly reactivated.
