Frequently Asked Questions

What is FirstNet?

FirstNet is a nationwide network dedicated to public safety is ready to help law enforcement, fire service, and EMS do their jobs safely and effectively. It is a series of frequencies set aside by AT&T that are inaccessible by their ordinary customer base, and given priority.

How Many Cellular Devices Can the Uniden Hero Series Support at One Time?

That varies depending on what model you’re using.

The U70 FN can handle up to 100 simultaneous FirstNet-enabled devices. The UM50 FN handles up to 10 devices in a vehicle. The UM2M FN enhances communication only to the device it is attached to.

Why are the LED Lights Turning Orange, Red, or Shutting Off?

There are certain cases where your system could be experiencing oscillation. This can be attributed to either the quality of your input signal or having your signal (outdoor) antenna and distribution (indoor) antenna too close together. Please review the following guidelines to help resolve this issue:

  1. Adjust the direction of the signal (outdoor) antenna. If the system is receiving a very high input signal, you can point your signal (outdoor) antenna away from the cellular tower to reduce the strength of the input signal and therefore, reduce the oscillation. Alternatively, if your system is receiving a very poor-quality signal (weak and unusable signal), you can point your signal (outdoor) antenna more directly towards the cellular tower to increase the strength of the input signal. Sometimes this may require completely repositioning the antenna to a location where you can achieve a line of site to the tower.
  2. Increase the separation between the signal (outdoor) antenna and the distribution (indoor) antenna. This can be achieved by increasing the distance between the two antennas or by placing barriers between them, such as moving the distribution (indoor) antenna to an adjacent room where there would be an additional wall separating them from the signal (outdoor) antenna.

All Uniden systems, including the Hero Series, can be returned within 60 days. It also comes with a 2 year warranty.
