For example:

•Check that the receiver is configured properly for the QAM type (256-QAM or 64-QAM).

•If using RF output, check that the RF signal level at the receiver is OK. The OAT100R signal level at the TV input (ANTENNA IN) must be between 0 to +7 dBmV. Also, check the RF power level at the receiver as well as the signal-to-noise ratio.

•If using IP output, check for an error-free Ethernet connection, and check the IP links at the switches.

•If configured for FTG Mode or another control system, verify the receiver has been set up properly.

*This chart assumes the OAT100R output mode (RF or IP) is properly configured (see Chart A). ** If the green LED is lit, there is a viable connection to the IP distribution network, but no traffic. If

the amber LED is blinking, there is intermittent traffic, but no streaming.
