On the 4-tuner HD PVR, why do Tuner 2 and Tuner 3 not show signal strength?
The tuner signal strength is not exact and differs slightly from unit to unit. It also depends on your dish, LNB, cable type, cable length, connectors (and how well they were fitted), etc. As long as your signal quality is 100%, the decoder should work correctly. In addition, different tuners show different signal strengths, as they are usually tuned to different channels and the signal strength differs from transponder to transponder (a transponder carries a bunch of channels and MCA uses about 11 of them). So, depending to what channel the tuner is tuned, the signal strength is also different. Tuners that are not being used tend to show no signal, so don’t let that worry you. If you want to test Tuner 2 and Tuner 3, get two recordings going and then check again. We also suggest you check the signal strength by tuning to M-Net, Animal Planet, KYKNet and the HD channel (channel 170). If the signal strength is fine on these channels, the decoder should work correctly.
