2.3 Duty Cycle Restriction

Due to the single channel of this band, the duty cycle is regulated to ETSI requirements. The duty cycle of the 
RM868500A is 10% averaged over the period of 1 hour. Meaning, if the next transmission will push the running average 
duty cycle over the 10% limit, the module will not transmit until enough time has elapsed to stay under the duty cycle.

Note:

 Because of heat restraints of the module, a 10% duty cycle over the period of 1 second will be enforced after the 

measured temperature of the module rises above 60°C.
