Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be guaranteed. Data
may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of data are rare
when wireless devices such as the router is used in a normal manner with a well-constructed network, the router
should not be used in situations where failure to transmit or receive data could result in damage of any kind to the
user or any other party, including but not limited to personal injury, death, or loss of property. Robustel accepts no
responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the
router, or for failure of the router to transmit or receive such data.
Safety Precautions
General
The router generates radio frequency (RF) power. When using the router, care must be taken on safety issues
related to RF interference as well as regulations of RF equipment.
Do not use your router in aircraft, hospitals, petrol stations or in places where using cellular products is
prohibited.
Be sure that the router will not be interfering with nearby equipment. For example: pacemakers or medical
equipment. The antenna of the router should be away from computers, office equipment, home appliance, etc.
An external antenna must be connected to the router for proper operation. Only uses approved antenna with
the router. Please contact authorized distributor on finding an approved antenna.
Always keep the antenna with minimum safety distance of 20 cm or more from human body. Do not put the
antenna inside metallic box, containers, etc.
RF exposure statements
1. For mobile devices without co-location (the transmitting antenna is installed or located more than 20cm
away from the body of user and nearby person)
FCC RF Radiation Exposure Statement
1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
2. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 20 centimeters between the
radiator and your body.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open.
Router may be used at this time.
Using the router in vehicle
Check for any regulation or law authorizing the use of cellular devices in vehicle in your country before installing
the router.
The driver or operator of any vehicle should not operate the route while driving.
Install the router by qualified personnel. Consult your vehicle distributor for any possible interference of
electronic parts by the router.
The router should be connected to the vehicle’s supply system by using a fuse-protected terminal in the
vehicle’s fuse box.
Be careful when the router is powered by the vehicle’s main battery. The battery may be drained after extended
period.

Remove SIM Card
1. Make sure the router is powered off.
2. To remove SIM card, press the card with fingers until pop out and then take out the SIM card.
3. Put back the slot cover and tighten the screws 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 specific M2M SIM card when the device is working in extreme temperature (temperature exceeding
0-40℃), because the regular SIM card for long-time working in harsh environment (temperature exceeding
0-40℃) will be disconnected frequently.
3. Do not forget to twist the cover tightly to avoid being stolen.

Two methods for mounting the router
1. Wall mounting:
Use 4 pcs of M2.5*4 flat head Phillips screws to fix the wall mounting kits 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 0.5 N.m, and the maximum allowed is 0.7 N.m.
2. DIN rail mounting:
Use 3 pcs of M3*6 flat head Phillips screws to fix the DIN rail to the router, and then hang the DIN rail on the
bracket. It is necessary to choose the standard bracket.
Note: Recommended torque for mounting is 1.0 N.m, and the maximum allowed is 1.2 N.m.
When mounting the kit onto the DIN rail, make sure that its metal springs are orientated towards the top
of the DIN rail.
2.8 Ground the Router
Router grounding helps prevent the noise effect due to electromagnetic interference (EMI). Connect the router to the
site ground wire by the ground screw before powering on.
Note: This product is appropriate to be mounted on a sound grounded device surface, such as a metal panel.
2.9 POE Connection
R2000 Dual’s four fast Ethernet LAN ports support POE feature (Voltage range: 48 to 57V DC), which can electrify the
network terminal devices such as IP camera and other WLAN AP etc. See figure below for more details.

adapter correctly. There are two cables associated with the power adapter. Following to the color of the head,
connect the cable marked red to the positive pole through a terminal block, and connect the yellow one to the
negative in the same way.
Note: The range of power voltage is 9 to 48V DC.
