# Warnings and Safety Notices

## Supplying Power

{% hint style="info" %}
It is recommended to first connect the [Power Splitter Cable](/hardware-and-interfaces/hardware/components-overview/power-supply-parts/power-splitter-cable.md) to the AIR/SCOUT NavBox before connecting the batteries (or drone power output). After shutting down the system (via the CPU button), first disconnect the battery/power supply from the Power Splitter Cable before unplugging the cable from the NavBox. This will prevent wear due to sparking on the MR30 input connector.
{% endhint %}

## Disconnecting Cables

{% hint style="danger" %}
Never connect or disconnect the I/O cable or any attached sensors/cameras from the I/O connector while the unit is supplied with power. This can lead to **damage to both NavBox and attached sensors/cameras**. Always shut down the unit completely and **unplug the power supply before disconnecting the I/O connector or any sensors**. \
\
In most cases, disconnecting the LiDAR/Camera cable from the I/O connector is never needed and the cable should be left connected at all times.
{% endhint %}

## Connecting Antenna Cables to the AIR NavBox

{% hint style="success" %}
Please note that the MCX (WiFi) and SMB (GPS) type connectors on the front panel have a limited number of **mating cycles**. Therefore we recommend leaving the provided MCX to RP-SMA WiFi pigtail and SMB to SMA GPS cable connected to the AIR NavBox whenever possible. **Frequent connects and disconnects should be performed on the SMA side of the pigtail cable only.**
{% endhint %}
