Error -7

If you cannot download clocking data over the network (Error -7) please check that your network connection is working. 

If you have a C250 Wifi clock check that the terminal has connection to the Wifi.   A Reboot may be required.

To check if the clock is connected to wifi, there will be a little W or signal bar at the top of the clock interface. If the W or bars are green, the terminal is connected to wifi (although may not have the correct IP). If the W is grey, the clock does not have the correct wifi details, or none input.
