3.10.4. DPR Signal

EM12-G provides a DPR (Dynamic Power Reduction) signal for body SAR (Specific Absorption Rate)
detection. The signal is sent by a host system proximity sensor to EM12-G module to provide an input
trigger which will reduce the output power in the radio transmission.
Table 15: Function of the DPR Signal
DPR Level Function
High/Floating Max transmitting power will NOT be backed off
Max transmitting power will be backed off by executing AT+QCFG="sarcfg"
Low
command
NOTE
Please refer to document [2] for more details about AT+QCFG="sarcfg" command.
