Lakala 4G machine for why the device connection is not successful

First of all, we need to check if the place where we are using the POS has network service. Some places may not have network or network connection to 2G, resulting in the POS can not connect to the network properly. Then it will prompt the inability to sign in and connect to the server, resulting in the inability to carry out subsequent transactions. Solution:Re-sign in at a suitable location with a good network, for example, try to connect to the network outside of the house, outside of a building, windows, and other places where it is easy to connect.

In the process of your signing in, you are always unable to sign in, and immediately return to the operator signing in after inputting operator 01 and password 000. At this point, we need to double check what the signal is on the POS device.

If the signal shown on the machine is empty or the signal is 0, then you can reopen the operation at the position where the signal is good. Of course, if the signal is full, there is a good chance that the POS traffic card has no traffic and needs to be recharged, or you can contact customer service to replace it with a new one and restart the check-in after replacement.

Signing in prompts server connection failure, connection overtime to ensure that it is not a signal problem. Try restarting. After the above operation is completed, if it still does not work, replace the traffic card and then restart can be. Of course, keep in mind that the general traffic card selection of mobile IoT card traffic card. This is of course the best choice. Unless specifically needed. If we sign in successfully, if the prompt: merchant restrictions, at this time you need to replace the products that can be swiped, there may be unexpected results.
