RoHS and WEEE Compliance
The Aprisa SR+ is 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).
4RF has worked with its component suppliers to ensure compliance with the RoHS Directive which came
into effect on the 1st July 2006.
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.
4RF 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).
4RF invites questions from customers and partners on its environmental programmes and compliance with
the European Commission’s Directives ([e-mail]).

Aprisa SR+ User Manual 1.5.3
Compliance General
The Aprisa SR+ radio predominantly operates within frequency bands that require a site license be issued
by the radio regulatory authority with jurisdiction over the territory in which the equipment is being
operated.
It is the responsibility of the user, before operating the equipment, to ensure that where required the
appropriate license has been granted and all conditions attendant to that license have been met.
Changes or modifications not approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
Equipment authorizations sought by 4RF are based on the Aprisa SR+ radio equipment being installed at a
fixed restricted access location and operated in point-to-multipoint or point-to-point mode within the
environmental profile defined by EN 300 019, Class 3.4. Operation outside these criteria may invalidate
the authorizations and / or license conditions.
The term ‘Radio’ with reference to the Aprisa SR+ User Manual, is a generic term for one end station of a
point-to-multipoint Aprisa SR+ network and does not confer any rights to connect to any public network or
to operate the equipment within any territory.

NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.

RF Exposure Warning
WARNING:
The installer and / or user of Aprisa SR+ radios shall ensure that a separation distance
as given in the following table is maintained between the main axis of the terminal’s
antenna and the body of the user or nearby persons.
Minimum separation distances given are based on the maximum values of the
following methodologies:
1. Maximum Permissible Exposure non-occupational limit (B or general public) of
47 CFR 1.1310 and the methodology of FCC’s OST/OET Bulletin number 65.
2. Reference levels as given in Annex III, European Directive on the limitation of
exposure of the general public to electromagnetic fields (0 Hz to 300 GHz)
(1999/519/EC). These distances will ensure indirect compliance with the
requirements of EN 50385:2002.
