7. Conditions for MD400 Operation

7.1. Important Warning

RACOM s. r. o. (hereinafter referred to as RACOM) is the exclusive owner of all rights to this operator manual. All rights reserved. Any duplication of this manual in any way, shape or form, or translation to any other language (without the prior written consent of the owner of the rights) is strictly forbidden. RACOM retains the right to make changes to the technical specification or functions of this product or to terminate production of this product, or to terminate service support of this product without advance written notice to the customer. RACOM firmware is available free of charge. Source code is the property of RACOM and is not available to any user. Any commercial use of the software with this licence is strictly forbidden. Changes to software and documentation are forbidden. RACOM firmware is released with the intention that it will be useful, however without any specific guarantees.

Under no circumstances is the Racom or any other company or person responsible for incidental, accidental or related damage arising as a result of the use of this product. The manufacturer shall not provide the user with any form of guarantee containing assurance of the suitability and applicability for its application. RACOM products are not developed, designed or tested for use in equipment which directly affects the health and life functions of humans or animals and neither as part of other important equipment, and RACOM does not provide a guarantee if company products are used in such equipment.

7.2. Conditions of Liability for Defects and Instructions for Safe Operation of Equipment.

Please read these safety instructions carefully before using the product:

  • Liability for defects does not apply to any product that has been used in a manner which conflicts with the instructions contained in this operator manual, or if the case in which the radio modem is located has been opened, or if the equipment has been tampered with.

  • The radio modem can only be operated on frequencies stipulated by the body authorised by the radio operation administration in the respective country and cannot exceed the maximum permitted output power. RACOM is not responsible for products used in an unauthorised way.

  • Equipment mentioned in this operator manual may only be used in accordance with instructions contained in this manual. Error-free and safe operation of this equipment is only guaranteed if this equipment is transported, stored, operated and controlled in the proper manner. The same applies to equipment maintenance.

  • In order to prevent damage to the radio modem and other terminal equipment the supply must always be disconnected upon connecting or disconnecting the cable to the radio modem data interface. It is necessary to ensure that connected equipment has been grounded to the same potential. Before connecting the supply cable the output source voltage should be disconnected.

  • Only undermentioned manufacturer is entitled to repair any devices.

  • CAUTION ! Risk of explosion on replacing the incorrect type of battery in the modem part. Dispose of used batteries in accordance with their manufacturer’s instructions. We recommend that lithium back-up batteries are replaced by RACOM service agents.

  • For ensuring the appropriate protection the manufacturer recommends powering the radio modem from an MS2000 power supply with short circuit current protection which acts as means of current protection for output circuits. If another power supply is used fuses, overcurrent protection or similar protective components should be used.

  • In threshold mode the radio modem is capable of operation at an ambient temperature of up to 70 °C. In such cases the temperature of the surface of the radio modem may reach high values, particularly in the case of the high end model “P” – the modem temperature may be up to several tens of degrees hotter than the ambient temperature, and therefore under these conditions the equipment needs to be protected against accidential contact. We recommend that operators who plan on using this threshold mode stick a warning sticker, in accordance with IEC 60417-5041 (DB:2002-10), on a visible part of the radio modem, or attach a sticker with the following text:

    Warning sticker IEC 60417-5041 (DB:2002-10)

    7.3. RoHS and WEEE compliance

    The routers are fully compliant with the European Commission‟s RoHS (Restriction of Certain Hazardous Substances in Electrical and Electronic Equipment) and WEEE (Waste Electrical and Electronic Equipment) environmental directives.

       Restriction of hazardous substances (RoHS)

    The RoHS Directive prohibits the sale in the European Union of electronic equipment containing these hazardous substances: lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs).

    End-of-life recycling programme (WEEE)

    The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment. Under the Directive, used equipment must be marked, collected separately, and disposed of properly. Racom has instigated a programme to manage the reuse, recycling, and recovery of waste in an environmentally safe manner using processes that comply with the WEEE Directive (EU Waste Electrical and Electronic Equipment 2002/96/EC).

    Battery Disposal—This product may contain a battery. Batteries must be disposed of properly, and may not be disposed of as unsorted municipal waste in the European Union. See the product documentation for specific battery information. Batteries are marked with a symbol, which may include lettering to indicate cadmium (Cd), lead (Pb), or mercury (Hg). For proper recycling return the battery to your supplier or to a designated collection point.

    7.6. Limitations of Use

    The MR400 radio modem has been developed for the frequency range 380 to 470 MHz, the MR300 for the frequency range 290 to 350 MHz and the MR160 for frequency 135 to 175 MHz. Specific frequencies are used for each country or region. A radio modem user must keep in mind that this radio device cannot be operated without the permission of the respective local radio spectrum administrator who provides a specific frequency for use and issues the appropriate permission for this.


    Users of MR400 radio modems in North America must be aware that because the 406.0 – 406.1 MHz frequency range is reserved only for the government the use of radio modems on these frequencies is strictly forbidden without proper permission.
