A new Dejavoo terminal takes just a few minutes to get up and running — if you know the order of the steps. This guide walks you through the entire Dejavoo terminal setup, from the moment you open the box to your first successful test sale. Dejavoo terminals, including popular models like the QD4, are known for fast contactless payments and a clear touchscreen, and the setup flow is the same across most of the lineup.
Before you begin, have three things ready: your Wi-Fi network name and password, your merchant terminal ID (TID), and a roll of thermal receipt paper. With those on hand, work through the six steps below in order and your terminal will be live and ready for customers.
1Unbox and power on your Dejavoo terminal
- Start your Dejavoo terminal setup by unpacking the box and confirming every part arrived: the terminal, the power adapter, the charging base (on the QD-series like the QD4), and any included receipt paper roll. Inspect the unit for shipping damage before you begin.
- Load a roll of thermal paper by opening the printer bay, dropping the roll in so the paper feeds from the bottom, and pulling a short tail past the cutter. Connect the power adapter and hold the power button until the Dejavoo logo appears. Let the device fully boot to the home screen before moving on.
2Connect to your network or Wi-Fi
- From the home screen, open the settings or gear menu and choose your connection type. For Wi-Fi models, select your network name from the list, enter the password exactly (it is case-sensitive), and wait for the signal icon to confirm the terminal is online.
- If you are using a wired Ethernet connection, plug the cable into the base or the terminal's LAN port and the device will pull an address automatically. A stable connection is the foundation of the whole Dejavoo terminal setup, so confirm connectivity before continuing.
3Load parameters and activate the terminal
- With the terminal online, you will download its parameters — the settings that link the device to your merchant account and processor. Open the setup or download menu and start the parameter download. The terminal contacts the host, pulls your configuration, and reboots.
- After it restarts, the device is activated and ready to process live cards. If the download stalls or errors out, double-check your connection and your terminal ID (TID). Our Puerto Rico team can push parameters remotely if you get stuck at this stage.
4Configure receipts and tip prompts
- Tailor the terminal to how you do business. In the receipt settings, add your business name, address, and phone number to the header, and choose whether customers get a printed copy, an emailed copy, or both.
- If you take tips — common for restaurants, salons, and bars — enable the tip prompt and set your suggested percentages (for example 15%, 18%, and 20%). You can also turn on tip adjustment so staff can add gratuity after the sale. These options make the Dejavoo terminal setup fit your counter, not the other way around.
5Run a test transaction
- Before your first real customer, run a small test sale to confirm everything works end to end. Ring up a low amount, then insert a chip card, tap a contactless card or phone, and swipe to verify all three read methods are working.
- Void or refund the test right away so it does not settle. Confirm the receipt prints cleanly and the tip and totals appear correctly. A successful test transaction is the final checkpoint that your Dejavoo terminal setup is complete and ready for business.
6Troubleshooting common issues
- If the terminal will not connect, restart your router and re-enter the Wi-Fi password, watching for a wrong character. If a parameter download fails, verify the TID and try again on a stronger signal. Declined test cards usually point to an activation step that has not finished — re-run the parameter download.
- For printing problems, reopen the paper bay and reseat the roll so it feeds from the bottom. If anything still looks off, reach out — local support means you talk to a real person who knows Puerto Rico merchants, not an overseas queue.
