While some basic functions, such as importing a schedule or firmware update from an SD card, can be done without pairing the SM Mini to a phone or tablet, full use of the device requires an iOS or Android device with Bluetooth version 4.0 or later. During the deployment, a phone or tablet can be used to check the status of the Mini from up to 20 meters away.
Before deploying the recorder for the first time, you must update the SM Mini's internal clock by pairing the recorder with the app. When you change the batteries, or if the batteries die, a rechargeable internal battery will keep the SM Mini's clock running for about a month until the primary batteries are replaced. If the primary batteries and clock battery die, you will need to pair with the recorder again to reset the clock before you can continue recording.
