(g) Frequency hopping spread spectrum systems are not required to employ all available hopping channels
during each transmission. However, the system, consisting of both the transmitter and the receiver, must be
designed to comply with all of the regulations in this section should the transmitter be presented with a
continuous data (or information) stream. In addition, a system employing short transmission bursts must
comply with the definition of a frequency hopping system and must distribute its transmissions over the
minimum number of hopping channels specified in this section.
(h) The incorporation of intelligence within a frequency hopping spread spectrum system that permits the
system to recognize other users within the spectrum band so that it individually and independently chooses
and adapts its hopsets to avoid hopping on occupied channels is permitted. The coordination of frequency
hopping systems in any other manner for the express purpose of avoiding the simultaneous occupancy of
individual hopping frequencies by multiple transmitters is not permitted. Note: Spread spectrum systems are
sharing these bands on a noninterference basis with systems supporting critical Government requirements
that have been allocated the usage of these bands, secondary only to ISM equipment operated under the
provisions of part 18 of this chapter. Many of these Government systems are airborne radiolocation systems
that emit a high EIRP which can cause interference to other users. Also, investigations of the effect of spread
spectrum interference to U. S. Government operations in the 902-928 MHz band may require a future
decrease in the power limits allowed for spread spectrum operation.

This Class B digital apparatus meets all requirements of the Canadian Interference Causing Equipment
Regulations. Operation is subject to the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Cet appareillage numérique de la classe B répond à toutes les exigences de
l'interférence canadienne causant des règlements d'équipement. L'opération est sujette aux deux conditions
suivantes: (1) ce dispositif peut ne pas causer l'interférence nocive, et (2) ce dispositif doit accepter n'importe
quelle interférence reçue, y compris l'interférence qui peut causer l'opération peu désirée.
