Precautions
1. General Precautions
PLEASE READ THESE GENERAL PRECAUTIONS AND KEEP A COPY OF THEM.
• ExpertLoRaWAN as a standalone item is designed for indoor use only. For outdoor use it must
be integrated into a weatherproof enclosure. Do not exceed the environmental and electrical
limits as specied in Technical Data.
• Avoid exposing the device to lighted cigarettes, naked ames or to extreme hot or cold
temperatures.
• Never try to dismantle the device yourself. There are no components inside the modem that
can be serviced by the user. If you attempt to dismantle the device, you may invalidate the
warranty.
• The ExpertLoRaWAN terminal must not be neither installed nor located in areas where the
surface temperature of the metallic case could exceed 85°C.
• Check that voltage and power available at installation is within range specied for modem. It
can be found on this guide and labelled on gateway.
• Do not install any gateway that is obviously damaged or suspected of having been damaged.
• In order to provide strain relief and to avoid transmitting excessive vibration to the device during
installation, all cables connected to ExpertLoRaWAN must be secured or clamped immediately
adjacent to the device’s connectors.
• To protect the power supply cables, and in order to comply with the re safety requirements,
when the unit is powered from a battery or a high current supply, a fast 1.25A fuse should be
connected in line with the positive supply.
• No compatible component or product must not be connected to ExpertLoRaWAN.
• Note! ExpertLoRaWAN distributors and sales ofces may refuse warranty claims where evidence
of product misuse is found.

2. Safety requirements and protection regulations
PLEASE READ THESE SAFETY INSTRUCTIONS AND KEEP A COPY OF THEM.
• ExpertLoRaWAN, for any type of operation, is only accessible for instructed and skilled installers,
testers and technical engineers.
• Before any type of handling of ExpertLoRaWAN, it must be ensured that it has been de-energized
to allow for electrical work to be carried out and it cannot be inadvertently re-energized.
• Always ensure that use of ExpertLoRaWAN is permitted. The modem may present a hazard if
used in proximity to personal electronic medical devices. As a rule, the modem must not be
used in hospitals, airports or planes.
• This equipment is not suitable for use in locations where children are likely to be present.
• Never use the device at a gas station, refuelling point, blasting area or in any other environment
where explosives may be present.
• Operating the device close to other electronic devices, such as antennas, television sets, and
radios may cause electromagnetic interference.
• This product is intended to be used with the antenna or other radiating element at least 20cm
away from any part of the human body. In applications where this rule cannot be applied,
the application designer is responsible for providing the SAR measurement test report and
declaration.
• You are responsible for observing your country’s safety standards, and where applicable, the
relevant wiring rules.
3. SIM Card Precautions
Before handling the SIM card in your application, ensure that you are not charged with static electricity.
Use proper precautions to avoid electrostatic discharges.
• When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card
holder.
• Caution! Do not touch these connectors! If you do, you may release an electrical discharge that
could damage the modem or the SIM card.
• When designing your application, the SIM card’s accessibility should be taken into account. We
always recommend that you have the SIM card protected by a PIN code. This will ensure that
the SIM card cannot be used by an unauthorized person.

4. Antenna Precautions
If the antenna is to be mounted outside the device, consider the risk of lightning. Follow the instructions
provided by the antenna manufacturer. Never connect more than one modem to a single antenna. The
modem can be damaged by radio frequency energy from the transmitter of another modem.
• Like any mobile station, the antenna of the gateway emits radio frequency energy. To avoid
EMI (electromagnetic interference), you must determine whether the application itself, or
equipment in the application’s proximity, needs further protection against radio emission and
the disturbances it might cause. Protection is secured either by shielding the surrounding
electronics or by moving the antenna away from the electronics and the external signal cable.
• The gateway and antenna may be damaged if either of them comes into contact with ground
potentials other than the one in your application. Beware: ground potentials are not always
what they appear to be.
5. Radio Frequency (RF) Exposure and SAR
Your wireless device is a low-power radio transmitter and receiver (transceiver). When it is turned on, it
emits low levels of radio frequency energy (also known as radio waves or radio frequency elds).
Governments around the world have adopted comprehensive international safety guidelines, developed by
scientic organizations such as ICNIRP (International Commission on Non-Ionizing Radiation Protection)
and IEEE (The Institute of Electrical and Electronics Engineers Inc.), through periodic and thorough
evaluation of scientic studies. These guidelines establish permitted levels of radio wave exposure for
the general population. The levels include a safety margin designed to assure the safety of all persons,
regardless of age and health, and to account for any variations in measurements.
Specic Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency energy
absorbed by the body when using a transceiver. The SAR value is determined at the highest certied
power level in laboratory conditions, but the actual SAR level of the transceiver while operating can be
well below this value. This is because the transceiver is designed to use the minimum power required to
reach the network.
ExpertLoRaWAN gateway has been approved for applications where the antenna is located more than
20cm from the body of the user. In all other congurations the user is responsible for meeting the local
SAR regulations.
Users of the ExpertLoRaWAN gateway are responsible for ensuring that they meet the SAR regulatory
requirements of the countries in which they intend to operate the device and that their documentation
contains the relevant SAR declaration, certication information and user guidance as appropriate.
6. SAR Information
Wireless Modules models: ELS81-E is marketed without a dened antenna.
The Maximum Antenna Gain when using indoor antennas depends on the distance from the antenna to
any nearby persons when in normal operation. It should not exceed the values shown on the table below.
According to the limit in 47 CFR 1.1310, we get the value of the maximum antenna gain as follows:
The maximum measured power output in the 900 MHz band is 1995.26 mW (33 dBm).

[e-mail] | webdyn.com
V1.0 subject to changes | Webdyn © by Flexitron Group
9
The maximum permissible exposure dened by 47 CFR 1.1310 is f/1500 = 0.6 mW/cm².
The maximum measured power output in the 1800 MHz band is 891.25 mW (29.5 dBm).
The maximum permissible exposure is dened as 47 CFR 1.1310 with 1 mW/cm².
According to the limit in 47 CFR 1.1310, we get the value of the maximum antenna gain as follows:
S = P*G/4πR²; G = 4πR² (S / P)
S = 0.6 mW/cm² or 1 mW/cm²
P = 1995.26 mW or 891.25 mW
R = 20 cm or 50cm
π = 3.1416
G(dBi)=10*log(G)
Solving for G; the maximum antenna gain is:
BAND P (mW / dBm) S (mW/cm²) DISTANCE MAX. GAIN (dBi)
900MHz 1995.26 / 33 0.6 20cm 1.7942
900MHz 1995.26 / 33 0.6 50cm 9.7530
1800MHz 891.25 / 29.5 1 20cm 7.5127
1800MHz 891.25 / 29.5 1 50cm 15.4715
7. Personal Medical Devices
Wireless devices may affect the operation of cardiac pacemakers, hearing aids and certain other implanted
equipment. If a minimum distance of 15 cm (6 inches) is maintained between the ExpertLoRaWAN
gateway radiating antenna and a pacemaker, the risk of interference is limited. If the user’s application is
likely to be situated in the vicinity of personnel, a suitable warning should be contained in the equipment
manual to this effect.
8. SAR Requirements Specic to Portable Mobiles
Mobile phones, PDAs or other portable transmitters and receivers incorporating a GSM module must
be in accordance with the guidelines for human exposure to radio frequency energy. This requires the
Specic Absorption Rate (SAR) of portable ELS81 based applications to be evaluated and approved for
compliance with national and/or international regulations.
Since the SAR value varies signicantly with the individual product design, manufacturers are advised
to submit their product for approval if designed for portable use. For European markets the relevant
directives are mentioned below. It is the responsibility of the manufacturer of the nal product to verify,
whether further standards recommendations or directives are in force outside these areas.
