# How to troubleshoot the 10-key cashier keyboard

> This article outlines the troubleshooting steps that should be followed if the POS 10-key cashier keyboard experiences communication issues

### **Restart the POS App**

* On the main cashier screen, select the **gear icon** in the bottom right corner of the screen. This will open the Device Status window.

* Select **Restart App** on the Device Status window.

* Attempt to log back into the POS app using the 10-key to confirm it's working.

**✏️** **Note -** If restarting the POS app does not fix the issue, proceed to the next section.

***

### **Restart the USB Hub**

* Locate the POS computer under the counter.

  * The POS Computer is a Mac Mini locked within a security mount.

* Locate the USB hub, which is plugged into one of the back ports of the POS computer.

  * The USB hub should have several USB cables plugged into it.

* Unplug the **host cable** of the USB hub from the Mac Mini, then wait 10 seconds.

  * The host cable is the main cable that connects all other peripherals to the Mac Mini. It is the only cable that is permanently attached to the USB hub.

* Plug the USB hub's host cable back into the Mac Mini.

* Test the 10-key to confirm it is communicating.

**✏️** **Note -** If unplugging and plugging back in the USB hub does not fix the issue, proceed to the next section.

***

### **Confirm the 10-key is plugged in**

* Look back under the counter to confirm all cables plugged into the USB hub are securely inserted.

  * There should be 2 to 3 USB-A cables leading into the USB hub.

    * Receipt Printer

    * 10-Key

    * **OPTIONAL:** Handheld barcode scanner (not included in all POS installs)

**Example of a USB-A cable head:**

* If any cables are not secured into the USB, have the store user plug them back in.

* Test the 10-key to confirm it is communicating.

**✏️** **Note -** If all cables are securely connected to the USB hub and the problem isn't resolved, proceed to the next section.

### Restart the Mac Mini

* On the cashier screen, use 3 fingers to swipe from the lefthand side of the screen towards the center.

  * If done correctly, this will minimize the POS app and display the home screen.

* On the home screen of the Mac Mini, tap and hold on the  icon in the top left corner of the screen.

  * A dropdown menu should appear below the  icon.

* Drag down to **Restart** on the dropdown menu, and let go to select it.

  * A new popup window should appear in the center of the screen.

* Tap the **Restart** button on the popup window.

  * **IMPORTANT**: The **Reopen windows when logging back in** toggle should be left blank.

* Once the system restarts, enter the admin password when prompted.

  * The password is **654321**.

* Log back into the VoriPOS app to confirm the 10-key is working.

**✏️** **Note -** If restarting the POS computer does not fix the issue, the 10-key's communication cable has likely been damaged. Reach out to the Vori support line for help on next steps.
