/ Removing Sync Cable from Cameras/ Using the Dual HERO System
To remove the Sync Cable, grasp Side  and remove it from the secondar y camera’s HERO Por t, then 
grasp Side  and remove it from the primar y camera’s HERO Por t, unhooking from primar y camera’s 
right side groove. Do NOT pull the cable connecting Sides  and  as this may damage the   
Sync Cable.
NOTICE : Do not connect or disconnect the cameras from the Sync Cable while the cameras are 
recording. Doing so may result in damage to the cameras and/or Dual HERO system. TO BEGIN RECORDING 
1.    Power ON Dual HERO System by pressing 
[  ] . Both cameras will power ON. 
2.  Select desired recording mode by 
pressing  [ 
 ] and choosing one of the 
options to the right.
3.  Press  [ 
 ]  to star t recording.
PRO TIP:  The camera’s LCD screens and red LED lights may not blink in sync. This is not a problem 
and has no effect on whether the cameras are properly synced with one another . Should the battery   
die or microSD card become full on either camera, both cameras will save the files and stop recording.

/ Mounting ConfigurationsMINI-USB PORT ON SYNC CABLE
When using the Dual HERO System with the Skeleton Backdoor, the Mini-USB Por t on the Sync Cable 
will be accessible and suppor t the following: •  Dual camera charging
•  Convenient content transfer
•  Composite video out (cable required, sold separately)
Note: External mic input is not supported.
WI-FI SUPPORT
The built-in Wi-Fi on your GoPro cameras allows your Dual HERO System to connect to the Smar t 
Remote, Wi-Fi Remote or GoPro App. The Wi-Fi will be accessed through the primar y camera only.   
The Wi-Fi on the secondar y camera is not needed and will be disabled, so preview of these files will   
not be available. To download and install the free GoPro App, visit gopro.com/software-app .
IMPORTANT: It is recommended to use dual Quick Release Buckles for mounting the Dual HERO System whenever possible 
for maximum stability. Using a single center-mounted Quick Release Buckle is only recommended while using the Suction 
Cup, Chesty, helmet mounts and other body-worn applications where high vibration or impact is less likely. Use of a single 
center Quick Release Buckle in high-vibration or high-impact scenarios can result in less stable video compared to using 
two Quick Release Buckles.

MOUNTING WITH CURVED OR FL AT ADHE SIVE MOUNTS
Flat Surface Mounting1.  Attach the Quick Release Buckles to the 
housing using the Long Thumb Screws.
2.  Attach the Quick Release Buckles to the   
Flat Adhesive Mounts.
3.  Remote the adhesive backing, align on  
mounting sur face and press firmly for   
10 seconds.
Curved Surface Mounting
1.  Attach the Extension Arms to the Quick Release  
Buckles using the Short Thumb Screws.
2.  Attach the Extension Arms to the housing 
using the Long Thumb Screws.
3.  Attach the Quick Release Buckles to the 
Curved Adhesive Mounts.
4.  Remote the adhesive backing, align on  
mounting sur face and press firmly for  
10 seconds.MOUNTING GUIDELINES FOR ADHESIVE MOUNTS
Follow these guidelines when attaching adhesive mounts:
•  Attach the adhesive mounts at least 24 hours prior to use. Allow 72 hours for complete adhesion.
•  Adhesive mounts must be mounted only on smooth sur faces. Porous or textured sur faces do not 
enable a proper bond. When applying the mount, firmly press it into place and ensure full contact 
over the entire sur face.
•  Apply adhesive mounts to clean sur faces only. Wax, oil, dir t or other debris reduce adhesion, which 
can result in a weak bond and risk of losing the camera should the connection fail.
•  Attach adhesive mounts in room temperature conditions. Mount adhesives do not bond properly   
if applied in cold or damp environments to cold or damp sur faces, or if the sur face is not   
room temperature.
For more information on mounts, visit gopro.com/support . 
WARNING: If using your camera with a GoPro helmet mount or strap, always select a helmet that 
meets the applicable safety standard. Choose the right helmet for your particular sport or activity 
and make sure that it is the right fit and size for you. Inspect your helmet to ensure that it is in good 
condition and follow the helmet manufacturer’s instructions on safe helmet use. Any helmet that has 
sustained a major impact should be replaced. No helmet can protect against injur y in ever y accident.

PRO TIP:  When removing the Quick Release Buckles from the adhesive mounts, push out both Quick 
Release Buckles evenly to avoid jamming the buckles. REQUIRE S FREE GOPRO STUDIO EDITING SOF T WARE 
Using the Sync Cable, the Dual HERO System allows you to record synchronized videos and photos. The 
Sync Cable enables the cameras to record video and photos much like your eyes see the world—with 
right and left lenses. While recording in sync, each camera saves the synchronized 2D videos or photos 
to its individual microSD card. In order to conver t the 2D files it a 3D video or photo, you will need GoPro 
Studio video editing software, available via free download at: gopro.com/software-app .
GoPro Studio makes creating 3D videos and photos easy. Simply impor t the video or photo files you 
want to conver t to 3D, click a button and the software automatically conver ts your synchronized 2D 
files into a single, viewable 3D file. Using the red/blue (anaglyph) glasses included with the Dual HERO 
System, you can view your 3D videos and photos on your compatible 3D T V or computer./ 3D Content Creation

WHEN CAP TURING FOOTAGE TO CONVERT TO 3D, FOLLOW THE SE GUIDELINE S FOR THE  
BEST RESULTS:
•  Maintain a distance of at least 3’ (1m) between the camera and subject. Other wise, it may be difficult 
to properly merge the files, and could cause eye-strain during playback.
•  Clean the camera and housing lenses prior to use. Differences in images caused by dust par ticles or 
water droplets on the individual lenses may cause eye-strain during playback.
PRO TIP:  To prevent fogging when using the Waterproof Backdoor, use GoPro’s Anti-Fog Inser ts 
inside your Dual HERO System by inser ting them into the three slots located directly below the 
secondary camera.
/ 3D Video Recording Tips
There are two ways to transfer files to your computer:  1.  Remove both cameras and use the USB Cable included with your camera to plug each camera in 
one at a time to your computer.
2.  Plug the USB Cable into the Mini-USB Por t on the Sync Cable and turn ON the Dual HERO System to 
transfer files simultaneously.
Choose one of the methods above and either press [ 
 ]  on the individual cameras, or press [  ] on  
your Dual HERO System. You will see “Removable Disk ” for PC and “NO NAME” for Mac on your computer.
IMPORTANT: Make sure to right-click the device icon and hit “Eject” before unplugging your cameras or the connected USB 
Cable from your computer. Failing to eject the device may corrupt files or cause other data damage.
