10.1. Frequency

RAy3 microwave links must be used in accordance with rules issued by the Telecommunications Authority for the area the device is operating in.

RAy3 microwave links must comply with the maximum permitted radiated power (EIRP) in accordance with conditions of the given country.

10.2. Safety distance

Safety distances with respect to the US health limits of the electromagnetic field intensity are in the Minimum Safety Distance tables below, calculated for different antennas and RAy power levels.

10.3. Professional installation

RAy units are only intended for installation by professionally trained people and in locations not accessible to the public. Installation and servicing must be carried out by personnel with appropriate technical training and knowledge of potential hazards.

RAy units shall be installed according to local Electrical Safety Codes. Each person participating on the installation has to respect all local standards and regulations for personal security and electromagnetic protection for everybody on the site. We also recommend to consult each site situation with local experts to ensure both the people and installed equipment are safe, the grounding and other protection are chosen reasonably for the actual site conditions. Trained staff must check that all parts recommended by experts regarding grounding and overvoltage protection of sensitive components or infrastructures are perfectly installed, so they effectively protect the equipment against typical situations.

It is the responsibility of the installer to ensure that all building and safety codes are met and that the installation is fully completed and equipment properly secured.

10.4. RoHS and WEEE compliance

This product is fully compliant with the European Parliament’s 2011/65/EU RoHS (Restriction of Certain Hazardous Substances in Electrical and Electronic Equipment) and 2012/19/EU WEEE (Waste Electrical and Electronic Equipment) environmental directives.
Used equipment must be 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.

Battery Disposal – This product may contain a battery. Batteries must be disposed of properly, and may not be disposed of as unsorted municipal waste within 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.

10.5. Liability for Defects and Safety Instructions

Please read these safety instructions carefully before using the product:

10.5.1. Ownership of product rights

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

10.5.2. Conditions of use

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.

10.5.3. Limitation of responsibility

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.

Under no circumstances is RACOM or any other company or person responsible for incidental, accidental or related damage arising as a result of the use of this product. RACOM does not provide the user with any form of guarantee containing assurance of the suitability and applicability for its application.

10.5.4. Product changes

The radio equipment 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.

10.6. Warranty

RACOM supplied parts or equipment (“equipment”) are covered under warranty for inherently faulty parts and workmanship for a warranty period as stated in the delivery documentation from the date of dispatch to the customer. The warranty does not cover custom modifications to software. During the warranty period RACOM shall, on its option, fit, repair or replace (“service”) faulty equipment, always provided that malfunction has occurred during normal use, not due to improper use, whether deliberate or accidental, such as attempted repair or modification by any unauthorised person; nor due to the action of abnormal or extreme environmental conditions such as overvoltage, liquid immersion or lightning strike.

Any equipment subject to repair under warranty must be returned by prepaid freight to RACOM direct. The serviced equipment shall be returned by RACOM to the customer by prepaid freight. If circumstances do not permit the equipment to be returned to RACOM, then the customer is liable and agrees to reimburse RACOM for expenses incurred by RACOM during servicing the equipment on site. When equipment does not qualify for servicing under warranty, RACOM shall charge the customer and be reimbursed for costs incurred for parts and labour at prevailing rates.

This warranty agreement represents the full extent of the warranty cover provided by RACOM to the customer, as an agreement freely entered into by both parties.

RACOM warrants the equipment to function as described, without guaranteeing it as befitting customer intent or purpose. Under no circumstances shall RACOM’s liability extend beyond the above, nor shall RACOM, its principals, servants or agents be liable for any consequential loss or damage caused directly or indirectly through the use, misuse, function or malfunction of the equipment, always subject to such statutory protection as may explicitly and unavoidably apply hereto.

10.8. FCC authorization of transmitters

FCC verification

RAy2-11 and RAy2-18-C were verified for compliance according to CFR 47 part 101 [see §101.139(a)].

FCC comment –
according to §101.141 and considering the low spectral efficiency the following modulations are not allowed in RAy2-11:

3.75 MHzQPSK
10 MHzQPSK, 16-QAM, 32-QAM

Except during anomalous signal fading. During anomalous signal fading, licensees may adjust to a modulation specified in their authorization if such modulation is necessary, to allow the licensees to maintain communications, even if the modulation does not comply with the capacity and loading requirements -101.141 (3).

FCC compliance

RAy2-24 complies with CFR 47 part 15.
