RF exposure near the antenna
Strong radio frequency (RF) fields will be present close to the antenna when the
transmitter is on. Always turn off the power to the ODU before undertaking maintenance
activities in front of the antenna.
Minimum separation distances
Install the ODUs so as to provide and maintain the minimum separation distances from all
persons.
The minimum separation distances for each frequency variant are specified in Calculated
distances and
power compliance margins on page 4-10.
Important regulatory information
Operation of the PTP 250 product involves its use 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 some countries radar systems are the primary users and the regulators have devised
special requirements to protect their operation from interference caused by unlicensed
devices. The unlicensed devices are required to detect the presence of radar systems and
avoid co-channel operation with the radar systems.
The PTP 250 system provides detection and avoidance functionality for countries and
frequency bands requiring protection for radar systems.
Installers and users are reminded that they must follow local regulations with regard to
any requirements for radar detection as well as transmitted power level. This can be
achieved by using the correct country code for the product concerned. Failure to follow
this could leave the installer and/or user liable to civil and/or criminal penalties.
Contact the Motorola helpdesk if you are unsure about any specific areas where you need
guidance.
