Is Your DJI Mic Receiver Frozen? (Try These Simple Fixes!)

If you’re in the middle of recording and notice that the DJI Mic receiver frozen, it could ruin the audio of your recording.

The issue can often be associated with a battery failure or a glitch with the firmware or software of the receiver. 

Don’t worry–this guide will walk you through the best solutions out there, so continue reading!

How to Fix When the DJI Mic Receiver Freezes?

Note: Have you tried pressing the receiver’s “Power” button multiple times in a row?

1. Execute a “Forced” Receiver Shutdown

If the DJI Mic receiver is frozen and won’t respond to normal presses, a forced shutdown can restart the software effectively.

The shutdown only works if the receiver is stuck in a “turned-on” state, with the display illuminated, otherwise, it may not be detected. 

• Hold the Power button on the receiver for ~30 seconds to force a shutdown!

So, the receiver should power off a few seconds after releasing the button and stay off until the button is pressed again.

Now, press the “Power” button again, but without holding it, and check if the receiver starts up normally.

If not, keep reading!

2. Jump-Start the Receiver & Transmitter

The frozen DJI receiver might be an indication of an underlying battery or charging problem.

Hence, we recommend “jump-starting” the DJI Mic equipment by placing both in the charging case and using the supplied USB Type-C cable to recharge the charging case battery.

Follow these steps to jump-start the DJI Mic equipment:

• Place the receiver and transmitter in the DJI Mic charging case.
• Connect the charging case to a charger with a USB Type-C cable.
• Allow the case to charge for at least 10–15 minutes before testing.

The DJI Mic components case uses standard charging equipment–the supplied USB Type-C cable and a 5V/2A adapter for outlet charging.

You can also use a computer to charge the DJI Mic equipment, but it would take much longer using a 2.0 or 3.0 USB port without an adapter. 

3. Check the DJI Mic Via a Computer

If your DJI Mic receiver is frozen, connecting it to a PC can help you determine if the problem is hardware or software-related.

All you need is the USB Type-C cable that came with your DJI Mic set and a Windows or macOS computer that is connected to the internet.

Checking the DJI Mic receiver drive consists of two steps:

Step #1: Connecting the Receiver:

First, locate an available USB 2.0/3.0 port on the case of your computer or laptop and connect the DJI Mic charging cable.

Now, connect the other end of the cable to the Type-C port on your receiver and wait until the system recognizes the connection. 

Step #2: Checking the Receiver Drive:

Even if there is no confirmation prompt that a new device has been connected to your system, you can check if the DJI Mic drive is accessible like so:

• Windows: Open File Explorer and look for a “DJI” or “Receiver” drive under “This PC”.
• Mac: Open the Finder and check if the receiver drive shows up on the device sidebar.

If the system recognizes the DJI receiver, it means that the problem is not software-related and probably lies with the battery. 

Note: Connecting the receiver to a computer allows you to download recording files more easily. 

4. Resynchronize the DJI Mic Receiver

So, a problem with the synchronization could be another reason why the DJI Mic receiver is not working, or the display stays frozen.

The transmitter and receiver are designed to synchronize automatically once both are placed inside the charging case, but this may not always work.

So, here’s how to manually sync the DJI Mic equipment:

• Hold the Record button on the transmitter for ~3 seconds.
• Place both the transmitter and receiver in the charging case.
• Wait for 20 seconds and remove the receiver to test.

Note: If the devices are synchronized successfully, a transmitter message should appear on the display of the receiver, which will “unfreeze” the device. 

5. Flash the DJI Mic Receiver Firmware

Your DJI Mic receiver might be frozen due to outdated firmware, and uploading the most recent firmware can eliminate the problem.

All you need is the USB Type-C cable, your receiver, and a computer or laptop with an active connection to the internet.

Follow these steps to update the firmware of the DJI Mic:

• Visit the DJI Mic Firmware page to download the latest firmware.
• Connect the receiver to your computer using the USB-C cable.
• Open the Finder or File Explorer on your Mac or Windows PC.
• Access the root directory of the DJI Mic receiver from the menu.
• Place the firmware.bin file you’ve installed in the receiver drive.
• Disconnect the receiver from your PC and check for any changes.
• Now, repeat the above instructions with the DJI Mic transmitter.

So, if the update has been detected and initiated successfully, an “Updating…” message should appear on the display of the DJI Mic receiver.

If not, attempt to roll back the firmware of the DJI Mic receiver by downloading an older firmware file from the official DJI website and then testing.

6. Replace the DJI Mic Charging Equipment

The DJI Mic receiver may freeze due to an inadequate power supply from a defective piece in your charging equipment, disrupting its functionality.

So, replacing the adapter and USB-C cable can ensure a stable power supply, potentially resolving the freezing issue.

6.1 Replace the AC Adapter

A malfunctioning adapter may fail to provide sufficient power and cause the receiver to freeze during operation.

So, install a new 5V/2A adapter, connect it to the USB-C cable and receiver, charge for 30 minutes, and verify that the receiver operates without freezing.

6.2 Replace the USB-C Cable

If the adapter functions, the USB-C cable may be defective and interrupt power delivery to the receiver.

Substitute it with a new USB-C cable, connect to the adapter and receiver, charge for 30 minutes, and confirm if the freezing is resolved.

7. Check the DJI Mic Receiver for Overheating

The DJI Mic receiver may freeze during an overheating, especially when the internal hardware temperatures have exceeded about 85F°(29.4C°). 

Excessive temperatures can be extremely harmful to the internal components of the DJI Mic, leading to permanent defects that will interrupt its functionality. 

How to Identify Overheating:

Overheating can be detected through the physical symptoms of the DJI Mic receiver. 

Start by checking if the receiver feels unusually hot to the touch, if the screen flickers, or if it shuts down unexpectedly during operation, apart from the frozen screen.

Try connecting and disconnecting the DJI Mic receiver from the charger multiple times and check for any changes. 

How to Prevent Overheating:

You can prevent overheating by stabilizing the internal hardware temperatures of the receiver as quickly as possible before permanent damage sets in.

Follow these tips to maintain optimal conditions:

Addressing overheating can prevent the DJI Mic receiver from freezing during operation.

If the receiver freezing is still there, we recommend waiting until your battery depletes completely.

8. Wait Until the Receiver Battery Depletes

If you’re that deep into the guide, but still, your DJI Mic receiver is frozen, maybe you should try to completely drain the battery.

This will force it to reset and break out from the frozen screen.

“Depleting” the battery means allowing the receiver to completely lose power, which will turn off the device, certainly, without having to do anything.

• Stop using the receiver and do not charge it right away.
• Wait for 1–3 hours until the battery is completely drained.
• Hold the Power button on the receiver for 10–15 seconds.
• Attempt to turn on the receiver with a single button press.
• Connect the receiver to the USB Type-C charger and wait.

Well, after the battery of the receiver has charged optimally, attempt to turn on the device with a single press of the “Power” button and watch the display. 

If this doesn’t help, we recommend discussing the matter with DJI customer support, as the problem could be on a hardware level!
