Firmware
upgrade
USB interface is used for batch firmware upgrading, but cannot
be used for sending or receiving data from slave devices which
connected to it. You can insert a USB storage device into the
router’s USB interface, such as a U disk or a hard disk. If there
have a supported configuration file or a router firmware in this
USB storage device, the router will automatically update the
configuration file or the firmware. For more details, see 3.6.6
Interface > USB.

2.6 Insert or Remove SIM Card/Micro SD Card
Insert or remove the SIM/Micro SD card as shown in the following steps.
Insert SIM card/Micro SD card
1. Make sure router is powered off.
2. To remove slot cover, loosen the screw associated with the cover by using a screwdriver and
then put the SIM card into the SIM slot/SD card slot.
3. To insert SIM card/Micro SD card, press the card with finger until you hear a click.
4. Put back the cover and tighten the screws associated with the cover by using a screwdriver.
Remove SIM card/Micro SD card
1. Make sure router is powered off.
2. To remove slot cover, loosen the screw associated with the cover by using a screwdriver and
then find the SIM card slot/SD card slot.
3. To remove SIM card/Micro SD card, press the card with finger until it pops out and then take
out the card.
4. Put back the cover and tighten the screw associated with the cover by using a screwdriver.
Note:
1. Recommended torque for inserting is 0.5 N.m, and the maximum allowed is 0.7 N.m.

2. Use the high temperature specific card when the device is working in extreme temperature
(temperature exceeding 40 °C), because the regular card for long-time working in harsh
environment will tend to disconnect frequently.
3. Do not forget to tighten the cover well to avoid the SIM/SD card being stolen.
4. Do not touch the metal of the card surface as information in the card may be lost or destroyed.
5. Do not bend or scratch the card.
6. Keep the card away from electricity and magnetism.
7. Make sure router is powered off before inserting or removing the card.

2.7 Attach External Antenna (SMA Type)
Attach an external SMA antenna to the router’s antenna connector and tighten. Make sure the
antenna is within the correct frequency range provided by the ISP and with 50 Ohm impedance.
Note: Recommended torque for tightening is 0.35 N.m.
The “MAIN” connection is REQUIRED, while the “AUX” is optional – modem behaviour may be more
stable in margin areas and in mobile applications when using the AUX connector.

2.8 Mount the Router
The router can be placed on a desktop or mounted to a wall or a 35 mm DIN rail.
2.8.1 - Two methods for mounting the router
1. Wall mounting (measured in mm)
Use 3 pcs of M3*4 flat head Phillips screws to fix the wall mounting kit to the router, and then
use 2 pcs of M3 drywall screws to mount the router associated with the wall mounting kit on
the wall.
Note: Recommended torque for mounting is 1.0 N.m, and the maximum allowed is 1.2 N.m.
2. DIN rail mounting (measured in mm)
