B3 · rev02 (October 2016), PE.5851.0039: match the separate dish/UHF inputs, front USB1, rear USB2, HDMI and separate RCA audio/video. A green LED means on; steady red means off/standby; flashing red means a software update. Do not disconnect power during an update. Read Info privately for CAID/SCUA and installed versions, not to start an update. Factory reset deletes settings and channels. Preserve the existing configuration; the manual’s historic service and tuning details are not current availability guarantees.
