Safety Information
WARNING: Failure to follow these safety instructions could result in damage to your
device and other surrounding property. Read all the safety information below before
using.
Handling
Handle your device with care. Your device can be damaged if dropped, burned,
punctured, crushed, or if it comes in contact with liquid. If your device is damaged,
do not continue using it, as it may cause injury. Use the correct input voltage. Do
not spray cleaning products on the device. Detach the power cord from the device if
the device emits an unusual smell or if there is smoke. Do not remove the microSD
card while it is saving or reading data. Remove the power cord from the device if
you are not planning to use the device for a long time. If the product is damaged or
the power supply is cut due to an accident, video may not be recorded.
Repairing
Do not attempt to repair the device yourself. Doing so will void the Warranty,
damage your device or may cause injury. If your device is damaged or is defective,
contact GRDIAN.
Distraction
Do not operate the device while driving. Operate only when your vehicle is parked.
Do not install the device where it interferes with the driver’s vision.
Exposure to Extreme Heat
ARC-4K and its accessories comply with applicable surface temperature standards
and limits. However, even within these limits, sustained exposure to heat for long
periods of time may cause damage to the device. Use common sense to avoid
situations where your skin is in contact with a device or its power adapter when it’s
operating or plugged into a power source for long periods of time. It is important
to keep ARC-4K and its power adapter in a well ventilated and shaded area when
in use.

Mounting the ARC-4K
Mounting the ARC-4K | Page 6
To mount your ARC-4K, you will need to use the Adhesive Magnet Mount and the
Clear Film Mount Protector. Follow the steps below to ensure proper mounting of
the ARC-4K.
1. Wipe and clean your rear view mirror so that it is free of dust and debris. Doing
so will help provide a stronger attachement of the ARC-4K to your rear view mirror.
2. Using the Clear Film Mount Protector, peel away #1 as indicated on the film.
Apply firmly at or near the center of your rear view mirror. Press down to make sure
the film is completely set.
3. Peel away #2 as indicated on the film. Next, peel away the Adhesive Magnet
Mount to expose the VHB tape. Carefully apply the Adhesive Magnet mount on top
of the clear film. Press down firmly to securely attach the mount to the Clear Film.
4. Securely fasten and lock the ARC-4K on top of the Adhesive Magnet Mount by
sliding the device into place. Slightly pull away the ARC-4K to make sure it is locked
in place and not just attached magnetically.
Place the clear film mount protector on
top of your existing rear view mirror. Place the magnetic mount on top
of the clear film.

Routing the Cables | Page 7
Routing the Cables
1. Locate a power source to plug the provided mini USB charging cable into.
3. Plug the mini USB into the ARC-4K and route the cable inside the headliner and
down the A Pillar. Tuck the cable into the rubber weather guard to hide wiring.
4. Continue down in the direction of your power source.
5. Tuck in any excess cable into nooks and crannies.
1. Peel away the 3M tape on the rear camera and place the camera at the center of
your rear windshield.
2. Connect the rear camera cable into the ARC-4K. Route the cable into the front
headliner through the A Pillar, B Pillar, C Pillar and then inside the rear headliner.
3. Tuck excess wires into nooks and crannies.

Troubleshoot | Page 15
The videos are blurry on playback. Why is my videos blurry?
Please make sure to remove and clean any debris found on the camera’s lens. If
the issue persists, contact our support team to have your camera lens refocused or
replaced.
My camera is not loop recording
Please use the SanDisk Max Endurance memory card.
Is the ARC-4K suppose to get this hot?
It is normal for the ARC-4K to get hot when left in direct sunlight. This will not affect
its performance.
Do I need a hardwire kit to use the Parking Mode Feature?
Yes, it is generally recommended to use a hardwire kit to use the Parking Mode
Feature. A hardwire kit protects your vehicle from battery drainage.
How do I remove the magnetic mount?
The magnetic mount uses 3M VHB tape. The VHB tape is a very strong adhesive. We
highly recommended using our Clear Film Mount Protector. The Clear Film Mount
Protector is a removable clear film that makes it easy to peel away your mount
without leaving any residue.
How do I view my videos?
The fastest and easiest way to view all of your recorded content is to view it on the
computer. Easily plug in your microSD into a compatible source and view all the
files on the computer.
What media player do you recommend?
You can either use our free-to-use HIT GPS Player or VLC media player. VLC is free
to download at https://www.videolan.org/
