3.1. Power supply
The R041 can be powered from a 12V to 35V DC power supply. Power(V+) and GND(V-) are clearly
indicated on the side terminal block. Ensure these are connected correctly. The R041 is equipped with
reverse polarity protection to protect the device in case of improper installation.
3.2. Reset
The
R041 can be restored to factory settings in the following way:
Ensure the R041 is in normal working mode: the power LED is steady on; the system LED flashes every
one second.
Use a pin to press and hold the Reset button for 5 to 10 seconds and then release it.
After releasing the button, all the LEDs will turn on and then off.
Wait for another 1 to 2 minutes until the System LED starts flashing every 1 second. This indicates that
the reset process has been successfully completed.
3.3. 4G SIM card
To get Internet connection via a 3G/4G mobile network, the R041 should have a 3G/4G data SIM
inserted, which is registered to a valid mobile operator account.
To insert a SIM card into the router, unscrew the two screws and remove the small cover as shown on
the image blow and insert the SIM card into the SIM card slot. For nano and micro-SIM cards a card
adaptor is required (not included with the router, normally comes with the SIM card).
