This error is related to the EFTPOS terminal connection which may have lost signal or is out of sync with the kiosk or the Verifone network. The possible causes are:
Low battery on the EFTPOS terminal or the battery ran out causing the disconnection
Network WiFi password has changed which means the terminal is not connected with the new password
The Network has disconnected from the Verifone network for other reasons
Please try the following steps:
Check the power connection to the terminal is correct and that there is enough battery % displayed on the terminal screen.
Check the WiFi, ethernet or network signal is respectively illuminated to indicate a connection to a network. If all of these are coloured orange, then you have an internet connection issue which requires reconnecting.
Power down the terminal using the 'X' button. Hold for 5-8sec until the terminal powers off. Turn the device back on and check the network connection and the battery %.
On the Kiosk, unlock the kiosk session by going to the cart, then press the lock icon and unlock the session. Go through the normal start sequence and "Check terminal status". If paired and synced with the EFTPOS terminal, then "Start trading" and test an order.
If the error still remains, then follow this process to check the Verifone network status:
Check the network password hasn't changed
Check there is sufficient battery
Press the # key, then 999 and enter. Select option 1 to Logon. If it approves, then you have network communications.
Next go into Setup, password is 999 to enter, then navigate to Pos config, select Yes and scroll down to VCLOUD. Select VCLOUD and find your WiFi network, select your WiFi network, then select 1 Receipt, and then Yes for Idle screen.
The Terminal will reboot and return you to the home screen.
Check the Logon one more time by pressing # then 999 and make sure it approves.
Return to the home/ Idle screen and try to place an order on the Kiosk or POS system.
If the above does not work, contact Verifone support.
