{% hint style="warning" %}
The controller should not be left in a hot vehicle or operated in direct sunlight. On hot days, keep the controller from getting hot, as this can prevent a stable connection to the drone.&#x20;
{% endhint %}

{% hint style="info" %}
Keeping the controller charged at about 40% will ensure long-range use. Use an external battery supply to keep the controller charged during operation.&#x20;
{% endhint %}

## TroubleshootingSome troubleshooting guidance which will help to resolve the questions quickly.

| Problem                             | Solution                                                                                                                                             |
| ----------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
| Unit doesn't turn on                | Make sure that the unit is charged. Connect the charger and try to power up the unit again.                                                          |
| Drone telemetry is not connecting   | Make sure that your radio module is turned on the modules are paired.                                                                                |
| Air module is not paired with ATLAS | Press and hold ATLAS reset button for 6 seconds. Press and hold Air module reset button for 11 seconds. After 30 seconds the modules will be paired. |
| I can't download the maps           | Internet connection is required to download the maps. Make sure that you have active WiFi or LTE connection on ATLAS.                                |
| Not charging                        | If the tablet is not turned off properly and is allowed to fully discharge, it can take several hours for the charger to regain a charge.            |
| Connection Issues                   | Most connection issues are related to the battery state of charge; under the 40% range, it can be reduced.  Closing AMC will cause he drone to RTL.  |
