2.1 The very first startup The modem has a super-capacitor part inside, which protect the device against possible shorter power outages. It can also provide RTC backup for the device, up to 2 days. Therefore, this supercap component can be charged and it can be exhausted after an outage or if you store the modem for months without connecting power source or using. Start the device by the adding the AC power (No. 1) or DC power (via USB port at No. 2) source and pushing the Reset button (No. 5) for 2 seconds by a sharp object (e.g. by a pen) – while the ON led will be also active (the PWR and ON leds are lighting by green colour) – then you can release the Reset button. Then the modem will start immediately and charging the supercapacitor (LADOWANIE SUPERKONDENSATORA led will be also active – by yellow colour). Next time you don’t need to push the Reset. You can stop it by removing the power source and start it by adding the power source. 2.2 Normal startup The modem has a pre-installed system (which contains the device firmware and the pre-configured OpenWrt® system). After adding the power source to the modem, you will just need to configure some necessary and unique settings for your SIM card, network access, and some other required connection parameters.

1. Ensure that you have inserted an activated SIM card into SIM holder (No. 3) in the right position. The usage of SIM holder is obligatory for using the wireless communication. 2. Ensure that antenna is mounted to the SMA interfaces (No. 6). 3. After plugging the AC power source (No. 1), the modem begins to perform booting – the LED signals are always showing the current activity during the operation. The system start needs about 40-50 seconds while it will be ready for usage, network communication. 4. During the boot, the modem begins to operate, whereas its LED signals are showing the current activity during the operation. During the boot sequence: a.) The MOC (power) and WL (ON) leds are also active (lighing by green). b.) Then the first two connection LEDs are (untitled ont he following figure) ligthing for ~10 seconds during the firmware start. c.) Then the 4G-WAN, USB leds will be also flashing for 30 seconds during the boot process.

e.) When the connectivity LEDs are not blinking anymore the load of the system has been finished. f.) The SILA SIGNALU (SIGNAL LEVEL) low LED(s) are blinking which means the modem tries to connect to the wireless network. If it was configured properly (APN, password and SIM PIN is matching) and the network registration was also succesful, the 4G-WAN led will be lighting with the SIGNAL LEVEL leds will be also lighting (by signing the current wireless signal strength). This means that the modem is already connected to the cellular network and it has enough wireless signal reception for the usage and wireless data transmitting. g.)

Important! In case of network outage, the wireless and wired data and interface connections, sessions will be reconnected as the power source estabilished and the network is reachable. IP settings: 1. By default the device IP address is static, the default IP address is: 192.168.10.1. 2. If you want to switch the USB-LAN interface (usb0) at network settings - at the EDIT part - to dynamic (at Protocol field), then the modem will waiting for an IP address on the network. 3. If you want to use the local DHCP server – to allow to add IP addresses by the modem for the connecting external networking devices – then the right setting is the Static Address, and the IP address should be also changed, and you have to uncheck the DHCP disabled optionfor the USB-LAN interface to allow the DHCP server. 4. In case of using DHCP server, you can define the IP range (Start, Limit) and you can define IPv4 netmask for your network. 5. When changing the Protocol field, you will need to push the button. Save your settings by the Save & Apply button. Then the bridged USB-LAN interface IP address will be changed according your request due to the new settings. 6. Further detailed settings can be found in the User Manual document.
