      1. What is the Master and Tracker device?
      The first paired device is called the Master device, which is used to receive tracking information and messages. Make sure to keep the Master device connected with your mobile phone. Your next paired device is the Tracker device, and the default work mode is "Message".
      The Tracker device has six work modes, the Message mode, Live Tracking mode, Beacon mode, Location on-demand mode, 6-level alarm mode, and Relay mode.


      1. What is the Message Mode?

      Devices in the Message mode would enable some other users to use it. Other users could select "Tourist mode" on the login page and connect to the device to send and receive messages. This mode is suitable for people who love outdoor exploration, mountaineering, fishing, skiing, and other activities that involved communication in an off-grid environment. 


      1. What is the Live Tracking Mode?        

      Live Tracking mode enables real-time positioning. Place the device on items that need to be monitored, such as buggy, seniors, children, pets, etc. The Master device will query the location according to the set tracking interval time, or you can manually query the location at any time.


      1. What is the Beacon Mode?


      Beacon mode allows periodic positioning by placing the device on items requiring periodic monitoring, such as luggage, valuables, bicycles, small vehicles, etc. The Tracker device will automatically send the location to the Master device.


      1. What is the Location on Demand Mode?

      The location on-demand mode stays connected to the Master device and could query the location as needed through Master. Place the device on items that have location requirements but do not need real-time locating. It is mainly used to prevent the loss, such as carry-on luggage.


      1. What is the 6-Level Alarm Mode?

      The 6-level alarm mode would send a message after triggering the movement, simply placing the device on stuff that needs to be protected from loss, such as bicycles, motorcycles in the outdoor storage of valuable personal items. You can adjust its sensitivity from 1-6 levels, that is when the device moves, it will send a notification to your Master device and App.


      1. What is Relay mode?
      Relay mode can extend the communication distance and forward the information sent by others. It does not automatically locate, but requires you to obtain the location manually. You can place the devices outdoors.


           12. What is the GPS Tracking Interval, and how do I set it up?

          20. What kind of GPS accuracy should I expect?

      We strongly advise you to visit the Official GPS Website  that clearly explains how the GPS technology works, not only for Radacat C2 MINI but for any other device that features GPS technology (like other GPS trackers and smartphones). The Official GPS Website states that GPS accuracy depends on the number of obstacles between the GPS satellites and the device itself (which, in our case, is the tracker). Good GPS accuracy: open outdoor areas (beaches, parks, or urban Bad GPS accuracy: very dense regions (forests or very crowded urban environments, with a high amount of obstacles); cloudy weather; the indoor use case is not advisable.
