PTP 450 Configuration and User Guide

RF exposure near the antenna
Radio frequency (RF) fields are present close to the antenna when the
transmitter is on. Always turn off the power to the PTP 450 unit before
undertaking maintenance activities in front of the antenna.
Minimum separation distances
Install the BHM or BHS so as to provide and maintain the minimum separation
distances from people.
Important regulatory information
The PTP 450 product is certified as an unlicensed device in frequency bands
where it is not allowed to cause interference to licensed services (called primary
users of the bands).
Radar avoidance
In countries where radar systems are the primary band users, the regulators
have mandated special requirements to protect these systems from interference
caused by unlicensed devices. Unlicensed devices must detect and avoid co-
channel operation with radar systems.
Installers and users must meet all local regulatory requirements for radar
detection. To meet these requirements, users must set the correct region code
during commissioning of the PTP 450. If this is not done, installers and users
may be liable to civil and criminal penalties.
Contact the Cambium helpdesk if more guidance is required.
USA and Canada specific information
The USA Federal Communications Commission (FCC) has asked manufacturers
to implement special features to prevent interference to radar systems that
operate in the 5250-5350 and 5470-5725 MHz bands. These features must be
implemented in all products able to operate outdoors in the UNII band. The use
of the 5600 – 5650 MHz band is prohibited, even with detect-and-avoid
functionality implemented.
Manufacturers must ensure that such radio products cannot be configured to
operate outside of FCC rules; specifically it must not be possible to disable or
modify the radar protection functions that have been demonstrated to the FCC.
In order to comply with these FCC requirements, Cambium supplies variants of
the PTP 450 for operation in the USA or Canada. These variants are only
allowed to operate with region codes that comply with FCC/IC rule.
