This article provides clear guidance on how to set up Wi‑Fi, manage cellular failover, turn the terminal on or off, and use airplane mode.
Before you begin
Before you begin, ensure the following:
You have access to the terminal passcode.
Your Wi‑Fi network name (SSID) and password are available if connecting via Wi‑Fi.
Connect to Wi-Fi for the first time
On the Welcome screen, select the arrow button.
On the Setup Wi-Fi screen, select the + sign.
Turn on the Wi-Fi toggle.
Select a Wi-Fi network from the list, or select the + sign and add the name (SSID) of the Wi-Fi network.
Enter the Wi-Fi password.
Select OK.
The terminal sets the network as the default automatically and connects to it.
You'll now see a Wi-Fi icon at the top of the display.
Change Wi-Fi connection settings
If you need to change the Wi-Fi connection, follow the steps below:
Select Settings.
Select Network.
Enter your passcode.
Select Wi-Fi. You can then:
Turn off Wi-Fi: Toggle off WLAN.
Select another Wi-Fi: Select a Wi-Fi network from the list, or select the + sign and add the name (SSID) of the Wi-Fi network. Enter the Wi-Fi password. Select OK.
Cellular 3G and 4G failover
Your S1E2L terminal can automatically switch to processing payments using a cellular connection when the internet connection fails.
Adyen terminals come with a pre-installed and activated SIM (eSIM) card, so you can use the cellular network immediately to board the terminal.
However, terminals boarded before 2022 might not have the SIM card activated if you did not set up the card subscription with us at the time.
Turn on/off
If you turn on the payment terminal for the first time or after it has been off for a long time, it may make a maintenance call to synchronise the configuration and update the software. This can take 10 to 20 minutes.
When connected to a power supply, the battery charges. An icon at the top of the display indicates the battery charge level.
Turn on the terminal:
Press and hold the power button until the display turns on. If necessary, connect the terminal to a power supply to charge the battery.
Turn off the terminal:
Press and hold the power button until a dialog box appears, then confirm you want to turn off the terminal.
