No Picture:

• Check video source is on
• Check TV and Modulator are tuned to same channel
• Check Free To Air signal is >60dB and it is connected to Antenna Input of Video Hub
• Check power LED is on on the Video Hub
• If no power LED, check powered by plug pack at Video Hub, or by Modulator input – NOT BOTH (For IR control – must be powered by Modulator)
• Check channel is at least 1 channel difference from the Modulator frequency and Free To Air frequency (refer interference).

Interference:

• Check channel is at least 1 channel difference from the Modulator frequency and Free To Air frequency
• Either way, try moving Modulator channel to different channel. If you can’t find a free channel a Frequency Filter can be purchased to clear a required frequency, and the Modulator can then be tuned to that frequency.
• Check <15dB difference between Free To Air and Modulator signal at input to Video Hub.
• If not, signals should be balanced using Gain Control (refer Installation Instructions)
• If the setup is NON IR and the modulator signal is too strong, use an inline attenuator on Modulator signal
