# How To Update

## Download Firmware Update File

{% content-ref url="/pages/bnRoqYlfx6PI9ZhE5GX9" %}
[Latest Version](/65r-sensor-user-guide/65r-sensor/firmware-update/latest-version.md)
{% endcontent-ref %}

## Before You Start

{% hint style="warning" %}
Data will be deleted during the firmware upgrade process. Make sure to copy the data off your sensor before performing the update.
{% endhint %}

{% hint style="info" %}
This Process works on Windows or Mac.
{% endhint %}

## Power On Sensor

Power the 65R using the AC adapters or keep it attached to the aircraft and turn the aircraft on. 

Then wait for the LEDS on the sensor to do the following:

| Power Method     | LED Behavior                                                                    |
| ---------------- | ------------------------------------------------------------------------------- |
| AC Power Adapter | Flashing Red                                                                    |
| Drone Power      | <p>Solid Green (Requires GPS Fix)</p><p>Solid Red (After 2 minutes w/o GPS)</p> |

This verifies that the sensor is fully booted.

## Connect Sensor to Computer

Connect the sensor to the computer using a USB cable.

{% hint style="info" %}
Use the USB-C port on the sensor not the USB-C port on the top of the gimbal.
{% endhint %}

{% hint style="warning" %}
Use the [USB-C Cable provided with the 65R](https://www.amazon.com/Anker-Powerline-Pull-up-Resistor-MacBook/dp/B01MZIPYPY?th=1). This cable gives the best and most reliable performance.
{% endhint %}

## Verify Connection

Open your wifi/network panel from the task bar. Verify that you see "unidentified network - No internet". This is the 65R appearing as a network device.
