Recommendations for Highly Reliable Radio Link:
• Maintain the use of Forward Error Correction (FEC) in challenging radio
environments such as urban areas. FEC is the default option in the ‘R2CR
Radio Data Receiver’ rmware.
• Use of Received Signal Strength Indication (RSSI) to measure the radio
environment before using GNSS receivers in a job site. RSSI value is
available to our end users through our GNSS eld application software,
which is an integral part of all GNSS systems. For more sensitive job sites
like airport construction, our customers and professional service team are
trained to use a spectrum analyzer and other typical radio tools to ensure
the environment is free from radio signal jamming or interference.
• Cooperation with the local radio-governing authorities to determine the
optimum free radio channel.
• Avoid using channels nearby local TETRA or television frequencies, which
generally are not recommended for use in this application.
• Use a repeater in an intermediate position, to extend the length of the link
and/or increase the receive signal level at the rover.

Regulatory and Safety Warnings
Product Conformity
Hereby, Topcon declares that the UR-1 radio modem is in compliance with
the essential requirements (radio performance, electromagnetic compatibility,
and electrical safety) and other relevant provisions described in Directive
2014/53/EU.
Therefore, the equipment is labeled with the CE-marking. The operating
frequency range of the device is not harmonized throughout the market area
and the local spectrum authority should be contacted prior to use.
Class A Digital Device Statement
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.
If this equipment does cause interference to radio or television equipment
reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Move the equipment away from the receiver.
• Plug the equipment into an outlet on a circuit different from that to which
the receiver is powered.
• Consult the dealer or an experienced radio/television technician for
additional suggestions.
Restrictions on Use
The UR-1 radio modem has been designed to operate only at specic
frequencies. The exact frequency in use differs from one region and/or
country to another. The user of a radio modem must take care that the
said device is not operated without the permission of the local authorities
on frequencies other than those specically reserved and intended for use
without a specic permit.
FH915 radio is disabled and not for sale in Europe.
Thermal Exposure Warning
If used in ambient temperatures over 55°C, the unit
must be located where it cannot be touched in normal
operation.
