Important regulatory information
Complying with rules for the country of operation
The PTP 670 product operates in frequency bands between 4.8 GHz and 5.9 GHz. These bands
are made available for licensed or unlicensed operation according to the individual rules and
regulations in force in each country.
Ensure that the equipment is operated in accordance with applicable regulations.
Obtain the necessary licenses or permits before using the equipment in licensed bands.
Some regional variants of PTP 670 are locked to a single country of operation. For the
remaining regional variants, use the Cambium Networks Support Centre to obtain a country-
specific license key for the country of operation. Country-specific license keys are automatically
populated with the list of regulatory bands allowed in that country.
In some regulatory bands, PTP 670 may be allowed as a secondary user of the band, where
operation is subject to the condition that the product does not cause interference to primary
users of the band. In this case, take care to avoid causing interference to primary users.
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.
The PTP 670 provides detect and avoid functionality for countries and frequency bands
requiring protection for radar systems.
Installers and users must meet all local regulatory requirements for radar detection. To meet
these requirements, users must install a license key for the correct country during
commissioning of the PTP 670. 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 specific information
Caution
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
•This device may not cause harmful interference, and
•This device must accept any interference received, including interference that may
cause undesired operation.

The USA Federal Communications Commission (FCC) requires manufacturers to implement
special features to prevent interference to weather radar systems that operate in the band 5600
MHz to 5650 MHz. These features must be implemented in all products able to operate
outdoors in the band 5470 MHz to 5725 MHz.
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 670 for
operation in the USA. These variants are only allowed to operate with license keys that comply
with FCC rules.
Other variants of the PTP 670 are available for use in the rest of the world, but these variants
are not supplied to the USA except under strict controls, when they are needed for export and
deployment outside the USA.
Canada specific information
Caution
This device complies with Innovation, Science and Economic Development Canada’s
licence-exempt RSSs. Operation is subject to the following two conditions:
(1) This device may not cause interference; and
(2) This device must accept any interference, including interference that may cause
undesired operation of the device.
Innovation, Science and Economic Development Canada (ISEDC) requires manufacturers to
implement special features to prevent interference to weather radar systems that operate in the
band 5600 MHz to 5650 MHz. These features must be implemented in all products able to
operate outdoors in the band 5470 MHz to 5725 MHz.
Manufacturers must ensure that such radio products cannot be configured to operate outside
of ISEDC rules; specifically it must not be possible to disable or modify the radar protection
functions that have been demonstrated to ISEDC.
In order to comply with these ISEDC requirements, Cambium supplies variants of the PTP 670
for operation in Canada. These variants are only allowed to operate with license keys that
comply with ISEDC rules. In particular, operation of radio channels overlapping the band
5600 MHz to 5650 MHz is not allowed and these channels are permanently barred.
In addition, other channels may also need to be barred when operating close to weather radar
installations.
Other variants of the PTP 670 are available for use in the rest of the world, but these variants
are not supplied to Canada except under strict controls, when they are needed for export and
deployment outside Canada.

Renseignements specifiques au Canada
Attention
Le présent appareil est conforme aux CNR d'Innovation, Sciences et Développement
Economique Canada applicables aux appareils radio exempts de licence.
L'exploitation est autorisée aux deux conditions suivantes :
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si
le brouillage est susceptible d'en compromettre le fonctionnement.
Innovation, Sciences et Développement Economique Canada (ISDEC) a demandé aux
fabricants de mettre en œuvre des mécanismes spécifiques pour éviter d’interférer avec des
systèmes radar fonctionnant dans la bande 5600 MHz à 5650 MHz. Ces mécanismes doivent
être mis en œuvre dans tous les produits capables de fonctionner à l'extérieur dans la bande
5470 MHz à 5725 MHz.
Les fabricants doivent s'assurer que les produits de radiocommunications ne peuvent pas être
configurés pour fonctionner en dehors des règles ISDEC, en particulier, il ne doit pas être
possible de désactiver ou modifier les fonctions de protection des radars qui ont été démontrés
à ISDEC.
Afin de se conformer à ces exigences de ISEDC, Cambium fournit des variantes du PTP 670
exclusivement pour le Canada. Ces variantes ne permettent pas à l’équipement de fonctionner
en dehors des règles de ISDEC. En particulier, le fonctionnement des canaux de radio qui
chevauchent la bande 5600-5650 MHz est interdite et ces canaux sont définitivement exclus.

Application firmware
Download the latest PTP 670 Series firmware and install it in the Outdoor Units (ODUs) before
deploying the PTP 670 equipment. Instructions for installing firmware are provided in
Upgrading software image on page 7-78.
Specific expertise and training for professional installers
To ensure that the PTP 670 is installed and configured in compliance with the requirements of
ISEDC and the FCC, installers must have the radio engineering skills and training described in
this section. This is particularly important when installing and configuring a PTP 670 system for
operation in the 5.1 GHz and 5.4 GHz UNII bands.
External antennas
When using a connectorized version of the product (as compared to the version with an
integrated antenna), the conducted transmit power may need to be reduced to ensure the
regulatory limit on transmitter EIRP is not exceeded. The installer must have an understanding
of how to compute the effective antenna gain from the actual antenna gain and the feeder
cable losses.
The range of permissible values for maximum antenna gain and feeder cable losses are
included in this user guide together with a sample calculation. The product GUI automatically
applies the correct conducted power limit to ensure that it is not possible for the installation to
exceed the EIRP limit, when the appropriate values for antenna gain and feeder cable losses
are entered into the GUI.
Antennas externes
Lorsque vous utilisez une version du produit sans antenne intégrée, il peut être nécessaire de
réduire la puissance d'émission pour garantir que la limite réglementaire de puissance isotrope
rayonnée équivalente (PIRE) n'est pas dépassée. L'installateur doit avoir une bonne
compréhension de la façon de calculer le gain de l'antenne de gain de l'antenne réelle et les
pertes dans les câbles de connections.
La plage de valeurs admissibles pour un gain maximal de l'antenne et des pertes de câbles de
connections sont inclus dans ce guide d'utilisation avec un exemple de calcul. L'interface
utilisateur du produit applique automatiquement la limite de puissance menée correct afin de
s'assurer qu'il ne soit pas possible pour l'installation de dépasser la limite PIRE, lorsque les
valeurs appropriées pour le gain d'antenne et les pertes de câbles d'alimentation sont entrées
dans l’interface utilisateur.
Ethernet networking skills
The installer must have the ability to configure IP addressing on a PC and to set up and control
products using a web browser interface.
