1. Remove the gearbox from the AEG body
2. Disassemble your gearbox and take out all the internals
3. Clean the gearbox case using solvent
4. Pay attention to the marked area. If you see that it is not smooth, use a metal file or grindstone to prepare the surface. The gearbox surface should be smooth, with no sharp edges which may damage TITAN II Bluetooth®.
> ⚠️ **Caution**
> ⚠️ If the PCB does not perfectly fit in your shell, make the necessary modifications to the gearbox shell, **not to the PCB**.
> ⚠️ It is forbidden to make any modifications to the PCB shell such as drilling the screw hole, grinding the edges of the PCB, etc. Doing so may result in immediate damage to the circuit, which is not covered by the warranty.
5. Carefully separate the TOP and BOTTOM boards of the TITAN II Bluetooth® unit from each other.
6. Place the BOTTOM board in the bottom part of the gearbox. Do not use a screw yet. Check if the board is laid flat in the gearbox.
7. Make sure that the electronic components found on the side of the fire selector board do not touch the gearbox case.
8. Use the (black) insulation washer from the INSTALLATION KIT.
> ⚠️ **Caution**
> ⚠️ The insulation washer must protect the circuit board. The metal screw and the metal washer cannot touch the board directly as this can result in a short circuit and TITAN II Bluetooth® damage, which is not covered by warranty.
9. Fasten the bottom board to the case. Use the original screw or the appropriate one from the INSTALLATION KIT.
10. Check if the screw is sticking out of the gearbox.
11. If so, add the metal washer(s) included in the kit. Make sure that the metal washer is placed between the screw and the insulation washer. It cannot be touching the circuit board directly.
12. Check that the TOP board of the TITAN II Bluetooth® unit fits into the gearbox without any collisions with its structure. The geometry of the TITAN II Bluetooth® allows the use of a mechanical bolt-catch lever. However, due to the different types of this solution depending on the manufacturer of the replica, it is necessary to pay attention to whether the solution used in your replica does not interfere with the PCB of the system before assembling the gearbox. Read more about compatibility here: [Is TITAN/ASTER compatible with KWA gearboxes?](https://help.gatee.eu/space/GHC/2035449937/Is+TITAN%2FASTER+compatible+with+KWA+gearboxes%3F)
13. Loosen the screw. Adjust the position of the BOTTOM TITAN II Bluetooth® unit board. The distance between the PCB and the bearing must be the same throughout (as indicated in the marked area).
> ✅ **Note**
> ✅ Sector gear sensor placement is very important. The red dot in the graphic below reflects the location of the gear sensor's photoelements.
14. Make sure the marked areas are not covered by the board or wires.
15. Check if the sensors are clean and not covered by wires.
16. Some gearboxes need modification. Check if your gearbox has the marked pins. If so, remove them.
Modification may also be required for the element indicated below. If its height exceeds 0.9 mm, it is necessary to grind it down so that it does not exceed the mentioned value along its entire length.
17. Check if both parts of the gearbox fit together perfectly.
18. Mount the trigger without the spring. Insert the TOP TITAN II Bluetooth® board. Close the gearbox. When the gearbox is closed, carefully check if the trigger can move smoothly and is not touching any TITAN II Bluetooth® components.
19. Mount the sector gear, the trigger with the spring, and the TOP TITAN II Bluetooth® board. Make sure that the gear is not touching TITAN II Bluetooth®.
20. If you intend to use accessories such as bolt-catch or magazine sensor, go to this section: [Installation of Accessories](https://help.gatee.eu/space/GHC/2854682625/User+Manual%E2%80%94TITAN+II+Bluetooth%C2%AE+V2+gearbox+drop-in+ETU+mosfet+AEG#Installation-of-Accessories). However, please note that if the sensors are trigger and selector sensors, they must be configured before configuring the engine itself. Install accessories before closing the gearbox and return here.
21. Close the gearbox. Tighten the two screws on the top part of the gearbox case.
21. Prepare the selector plate. If the selector plate does not have a copper connector, you need to modify it. The black surface does not reflect light, so sensors will not work properly.
22. In order to modify the black plate, use a sticker from the INSTALLATION KIT. Try the sticker with the thinner black line first.
> ✅ **Note**
> ✅ If the selector plate has a copper connector, do not make any modifications.

> ⚠️ **Sensor auto-calibration is only possible when the trigger or selector in the replica is uncalibrated and the replica is equipped with a 3-position selector.**
Trigger and selector auto-calibration allows the replica to be used without the need for prior sensor calibration via the GCS app or the trigger.
> ℹ️ The user does not need to perform any special actions – it is enough to switch the selector through all three positions and press the trigger several times during normal use. The selector calibration process will be completed once the ETU detects all three selector positions.
> 📝 **To calibrate the trigger, simply press it fully and release it smoothly, just like during normal shooting.**
> ℹ️ After pressing the trigger, the replica will begin firing in the mode corresponding to the selected selector position.
> ✅ Please note that the first few shots and the initial detection of the fire selector position may be slightly inaccurate. This is **an expected part of** the system’s auto-calibration process. After a few firing cycles and several selector changes, the system will self-adjust and begin to operate flawlessly.
Performing trigger and selector auto-calibration does not exclude the possibility of calibrating the sensors via the GCS app. The user can recalibrate the sensors at any time by connecting to GCS or restoring the TITAN II to factory settings.

### Configuring Magazine Capacity Simulation
1. Go to the **Magazine **tab
- **Magazine mode** – means enabled or disabled magazine simulation mode and the need to reload the magazine
- **Magazine Capacity** – here you can set the real or predefined number of BBs that are in the magazine and after which the replica will stop firing and you will need to reload it
- **Reload Time** – the amount of time which prevents the replica from firing after emptying the magazine of a predefined number of BBs. Does not work when you have set the magazine and bolt-catch sensors. Represents the time needed to reload the replica – after this time has elapsed, you can continue to fire.
2. Activate the magazine simulation mode and go back to the previous screen and save changes
3. On the main screen of the magazine settings, go to the **Magazine Capacity **tab
4. In the **Magazine Capacity** tab, set the number of BBs after which the replica will stop firing and a reload sequence will be required.
The reload time does not matter when using the magazine sensor and bolt-catch. It can be left at the default value.
## Disabling the magazine simulation mode
1. To disable Magazine Simulation Mode, go to the **Magazine **tab and change the position of the **Magazine Mode **switch to **OFF**
> ⚠️ **Caution**
> ⚠️ Because of the installed bolt-catch button, disassemble the upper receiver very carefully, so as not to damage the sensor or wires. Disassembly should be carried out checking the position of the wires and the bolt-catch sensor at all times.
> ⚠️
> ⚠️ Please bear in mind that damage to the bolt-catch button and its wires is not covered by the warranty. If necessary, you can find spare parts at [http://gatee.eu](http://gatee.eu).
# Quick Access Menu
## Pre-Cocking
You can access **Pre-Cocking **using a shortcut without connecting the unit to the GCS app. In GCS, go to **Trigger>Pre-Cocking>Switch Mode via Selector** and use the toggle button to activate this function.
1. Fire a shot on SEMI, BURST or pull the trigger while in SAFE mode (only if the safety lever has been removed) **and** **do not release the trigger**.
2. Switch the selector within 2 s. There is a single low frequency vibration.
3. Switch the selector in any order to change between the options indicated by vibrations:
1. 1 low vibration – Pre-Cocking Off
2. 2 low vibrations – Pre-Cocking Auto
3. 3 low vibrations – Pre-Cocking Manual
4. Release the trigger to save the selected mode.

*If defined in GCS
## De-Cocking
Forcing the piston release after firing with Pre-Cocking enabled
1. Press the trigger in SEMI or BINARY mode and wait for the firing cycle to end – do not release the trigger.
2. After 1.5 s, a high, medium, high, medium, high, medium frequency audible message will be triggered.
3. Releasing the trigger after the sound message is equivalent to firing without Pre-Cocking. The piston remains in the rest position.
> ✅ **Note**
> ✅ Releasing the piston to the rest position does not mean that Pre-Cocking mode is deactivated. Each subsequent shot after pressing the trigger will be made with the piston cocked according to the selected Pre-Cocking mode.
## Alternative SAFE mode
If the user has configured the selector so that SAFE mode is not assigned to any selector position, the user can activate SAFE mode at any time by doing the following:
1. Set the selector lever to SAFE
2. Change the selector position to SEMI
3. Return to SAFE position again.
> ⚠️ **Caution**
> ⚠️ Note that the above sequence must be performed within 0.5 s. Activation of SAFE mode will be confirmed by a short low tone vibration. The SAFE mode is deactivated when the fire selector position is changed.
# Restoring Factory Settings

# Troubleshooting
## My replica fires multiple shots with a single trigger pull – no DTC in the GCS app
A combination of a very soft spring and high trigger sensitivity may cause unintended firing of the replica. A trigger with a soft spring easily transmits vibrations caused by the gearbox cycle, which can lead to additional, uncontrolled shots.
Possible solutions to the issue:
- install a stiffer trigger spring
- adjust the trigger sensitivity settings in the GCS app and increase the reset point distance from the firing point (increase the trigger travel needed to fire a shot)
- recalibrate the trigger in the GCS app
- if you encounter any issues, please contact us via [https://help.gatee.eu](https://help.gatee.eu)
## Unable to update firmware of my TITAN on Android device
Your device is likely paired directly with your phone. You need to unpair it, as the connection should only be made through the GCS app.
