S-RGB V4 Instructions
Before use, charge the saber fully with the provided cable and charging block. Make sure to not supply more than 5V and 1A output to the saber or charge the saber while it's on. If those numbers mean gibberish then don't worry, that's what the charging block is for!
Charge for about 2 hours for but make sure not to leave it completely unattended.
To insert the blade, use the provided hex key to loosen the emitter blade retention screws. Insert the blade and tighten the screws just enough to hold the blade in place with friction.
Be careful not to over-tighten, as this will dent and damage the blade. Light marks on the blade from the set screw is expected.
Features
S-RGB V4 comes with a large library of sound fonts (27) already on the SD card but you can add even more just by dragging and dropping it on the SD card. There are 3 blade styles and you can easily toggle between them or set colours via the mobile app!

Adding Background Music
Some but not all of the default sound fonts have background tracks already.
If you wish to add tracks to a sound font make sure that they are:
- saved as .wav files
- bitrate of 44100 Hz
- saved without any metadata
Tracks are stored in each individual sound font folder with the following naming format track#.wav or track (#).wav. If you have multiple track files, make sure they are named in numeric sequential order. When playing background music the tracks would be selected at random.

Saber Customization
SD Card Customization
You can add sound fonts on the SD card with numerically ordered folder names. S-RGB V4 can take Proffie formatted sound fonts.
You can also change blade styles in the "config.ini" file in the "set" directory.
Mobile App
In addition to the SD card, you can more easily customize the saber via Bluetooth using a mobile app. The app "ForcePark" is available on Android through the Google Play Store and iOS on the App Store.
It currently has the below icon:
Note: The iOS version of the app is currently experiencing connectivity issues. The engineering team from TXQ is looking into resolving this in a future firmware update.

Battery Removal and Insertion
Some sabers may use an external battery charger which require removing the battery to recharge it. You may also want to remove the battery to reseat it in your ECO Saber or charge it externally. Below is a demo showing how to remove the battery from the tight battery holder and re-inserting it back in the core.Saber with multiple blade retention screws
What if my saber has multiple blade retention screws? Should I tighten them all in?
Good question, here are some diagrams to illustrate which ones you should tighten. The blade retention screws are marked in blue and the contact points acting on the blade are marked in red.
In the middle diagram with all retention screws tightened, the red areas marked in red are the surface area contact points of the blade. Note how it's only really making contact with the 4 retention screws and the opposite ones are counteracting against each other.
Whereas in the 3rd diagram on the right, where only retention screws on the same side are tightened, the blade has much more surface area contact with the inside wall of the hilt itself.
It's preferred to tighten retention screws on the same side, or 90 degrees from each other so the blade has more surface contact which results in it being held in the saber tighter.
