Internal Batteries
Thereceiverfirstdrawspowerfromaconnectedexternalpowersource.Whenthereisnovalidexternalpowersource
connectedorifthesourcehasdischargedlowerthan6.5V,thereceiverwilldrawitspowerfromtwohigh‐capacity
internalbatteries(non‐removable).Dependingontheusecase,thehoursof
operationprovidedbytheinternalbatteries
vary,asshownin
Table9.
Powerinputgreaterthan30VDCcoulddamagethereceiver.
Thebatteriesareshippedfromthefactorywithapartialcharge.Formaximumoperatingtime,fullychargethe
batteriesbeforeusingthereceiver.
