# Pairing a Wireless Tool to a Controller

The pairing of a Mechatronic Wrench to a controller is done differently than other wireless tools, and requires an MWRKit to be connected to the controller. Please refer to the tool's Product Instructions for more detailed information.

Before you start the pairing process:

- Make sure to have virtual stations available.

- Make sure Bluetooth is enabled in the Controller.

- Make sure there are pairing slots available (6 for Bluetooth).

- Check which radio channel to use

- Check how to put the tool into pairing mode. See the corresponding documentation for the tools to be paired or follow the instructions below.

- If possible, have a clear line of sight between tool and controller.

- Make sure no other tools are being paired with the controller at the same time.

1. Enable Bluetooth on the controller by going to the Settings tab, selecting Wireless on the left pane and then going to the Bluetooth window. Drag the Enabled switch to On.

2. Set the radio channel to be used with the wireless tool. On the home view, go to the Settings tab, select Wireless on the left pane and then go to the Bluetooth window. Drag the Enabled switch to On.

3. Return to the home view and go to the Tool tab. Then, select the plus icon in the upper-right corner of the screen to start the pairing.

4. Put the tool in pairing mode.

5. On the Pairing dialog box, select Bluetooth to start the pairing process.

6. The pairing process will end with one of the following results:

   - Pairing successful: The tool has been paired to the controller using the selected channel.

   - Pairing unsuccessful: This can be due to any of the following reasons:

     - No tool detected during the pairing process. Make sure the tool is in range and in pairing mode, and then select Close and try again.

     - More than one tool was found during the pairing process. Make sure no other tool is in pairing mode, and then select Close and try again.

     - Pairing already in progress. Make sure no one else is performing the pairing process on the controller, and then select Close and try again.

     - Pairing failed. Select Close and try again.
