General steps before raising RMA request
Some feature seems to not working
Have your device the latest FW version?
If you think that some of the feautures does not work, then please check whether your device has the latest FW version or not. You can check FW version in section "System->Maintenance->System->Firware version".
Once you will check FW version of your device, please go to our website (http://www.2n.cz/en/products/intercom-systems/ip-intercoms/?targetView=menu), pick your particular model and then in section "Download->Firware" check if you really have the latest version. If not, then please download the latest one and upgrade the intercom in section "System->Maintenance->Upgrade Firmware".
If situation fill remains the same you also can optionaly make Reset configuration in same section. It sometimes helps for instance after FW ugprade. If this wont help either then please contact the tech. support and describe your issue and send configuration backup. Please keep on mind, that functionality of most of the features is SW related and if you will discover any malfunction, then it is probably a bug and once you will report it to the tech. support, it will be forwarded to R&D and fixed as soon as possible.
Possible HW failure
Camera or extending module does not work, what can I do?
If anything what is somehow connected via connector to PCB of the intercom does not work properly then please check the connection and also the cables. For instance in case of 2N® Helios IP Verso try to use spare bus cable if you have any. Also if you have possibility to try this module on another intercom of same model, please do so to find out whether intercom itself is faulty or just the module. This is applied to all the modules in 2N® Helios IP family.
Intercom is restarting when opening a door, what can I do?
If intercom restart itself everytime you tries to open the door, then power source (whether POE or 12V external power supply) is probably to weak. Intercom has a watchdog, which restart intercom everytime when it does not have enough power for operation and triggering the lock at the same time to prevent it's damage. Please try to use different power source or lock with less consumption.
Intercom does not get IP address from DHCP server, what can I do?
Please note that in default intercom always has DHCP enabled. If it does not get IP address from DHCP server, please doublecheck your network equipment and check if different device will be able to obtain address from DHCP server on the same port as the intercom.
