An amazing feature that is built into your TrackR app, is the ability for your TrackR to ring your phone - simply by pressing the button on your TrackR! However, if you are disconnected from your phone's Bluetooth (either out of range or it is turned off) or have the TrackR app force closed, then you will hear the TrackR make a two beep tone, one high and one low when you press its button. Once you are back within Bluetooth range or turn your phone's Bluetooth back on, then you will be able to ring your phone by pressing the TrackRs button.
While being out of range is the most common reason for your TrackR to give you the two-tone beep, it can also occur when trying to pair your TrackR with a new phone. It can be very frustrating when you are trying to pair your TrackR but you keep hearing this two-tone beep and it never seems to connect! Luckily, this issue is easily solved by simply removing the battery and re-inserting the battery. This will reset the TrackR so it will properly connect.
