that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
Hazardous voltages may occur within this unit when connected to a power supply.
Prevent access to hazardous voltages by disconnecting the unit from its power
supply.
Prevent damage to internal electronics from electrostatic discharges (ESD) by
discharging your body to a grounding point (e.g. use of wrist strap).
Before installation:
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.
This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Installation section).

General
Remember to follow any special regulations and warnings in force in any area and never
use the unit whenever it’s forbidden to use it. Do not use the unit when it may cause
interference or danger. A wireless device exposed to interference above specified limits
could result in deteriorated performance.
Hospitals or other Medical environment
Do not use the unit in a medical environment such as health care facilities. Follow any
regulations or rules that instruct you to not use the unit.
Pacemakers
The Health Industry Manufacturers Association recommends that a minimum separation
of six (6”) inches be maintained between cellular wireless equipment and a pacemaker
to avoid potential interference with the pacemaker. These recommendations are consist-
ent with the independent research by and recommendations of-Wireless Technology
Research.
Persons with pacemakers:
… Should ALWAYS keep the the unit and its antenna more than six inches from their
pacemaker when the unit is turned ON.
… If you have any reason to suspect that interference is taking place, turn your wireless
equipment OFF immediately.
Hearing Aids
Some digital wireless equipment may interfere with some hearing aids. In the event of
such interference, you may want to consult your service provider [or call the customer
service line to discuss alternatives.]
Other Medical Devices
If you use any other personal medical device, consult the manufacturer of your device to
determine if they are adequately shielded from external RF energy.-Your physician may be
able to assist you in obtaining this information.
Turn the wireless equipment OFF in health care facilities when any regulations posted in
these areas instruct you to do so. Hospitals or health care facilities may be using equip-
ment that could be sensitive to external RF energy.
Aircraft
Do not use the unit in an aircraft. The use of a wireless unit in an aircraft may be danger-
ous to the operation of the aircraft, disrupt the wireless network, and may be illegal.
Failure to observe these instructions may lead to suspension or denial of cellular services
to the offender, legal action, or both.
Vehicle
If the unit is incorrectly installed in a vehicular environment, the operation of the unit
could interfere with the vehicle electronics. Faulty installation and/or operation can con-
stitute a safety hazard.

For Vehicles equipped with an airbag
An air bag inflates with great force. DO NOT place objects, including either installed or
portable wireless equipment, in the area over the air bag or in the air bag deployment
area. If in-vehicle wireless equipment is improperly installed and the air bag inflates, seri-
ous injury could result.
Blasting areas
Do not use the unit where blasting is in progress or in “blasting areas”.
Observe restrictions and follow any regulation or rules.
Explosive atmospheres
Do not use the unit in any area with a potentially explosive atmosphere.
Potentially explosive areas are often, but not always, clearly marked.
They include fuelling areas such as petrol stations, below decks on boats, fuel or chemical
transfer or storage facilities, and areas where the air contains chemicals or particles, such
as grain, dust, or metal powder.
RF energy
The unit is a low power radio transmitter and receiver. When it is ON, it receives and
also sends out radio frequency (RF) signals.
Most modern electronic equipment is shielded from RF signals. However, certain elec-
tronic equipment may not be shielded against the RF signals from the wireless unit. All
radio-transmitting devices send signals, which may cause interference in different elec-
tronic devices. To avoid interference, place the units antenna a sufficiently long distance
from other electronics.
Critical applications
Cellular units operate using radio signals and cellular networks cannot be guaranteed to
connect in all conditions. Therefore you should never rely solely on a wireless device for
essential communications, for example medical emergencies.
Backup copies
Remember to make backup copies of all important data, for example PIN/PUK codes,
contents of SIM card etc.
Antenna care
Use only the supplied or an approved replacement antenna. Unauthorized antennas,
modifications, or attachments could damage the unit and may violate current regulations.
Do not touch the antenna unnecessarily when the unit is in use. Contact with the anten-
na affects call quality and may cause the unit to operate at a higher power level than
otherwise needed.
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.

Description
Remote access removes boundaries, eliminates the need for time consuming site visits
and provide a network infrastructure suitable for today's “always-on” society.
The MRD-350 industrial mobile broadband GPRS / EDGE / 3G router uses the Internet
to cost effectively inter-connect systems, allowing HMI, PLCs, sensors etc to communi-
cate with each other.
A compact design bundled with all interfaces and LEDs in the front make the unit
extremely well suited for industrial applications. With isolation between the PSU and the
Ethernet and serial ports the MRD-350 protects against issues caused by ground loops.
The dual SIM support in the device ensures that site connectivity is not dependent on a
single carrier, should something happen the unit just switches to the other SIM.
Devices connected to the Internet require countermeasures towards cyber threats. The
MRD-350 offers protection of transmissions from malicious eavesdroppers via encrypted
communication tunnels (VPN), and features a simple, yet powerful, packet inspection
firewall.
For solar powered applications energy efficiency is vital and the MRD-350 has a special
low-power mode to only be fully powered when needed. The MRD-350 with its built-in
serial port offers a simple router replacement solution with the benefit of not having to
reprogram or change any other component.
