FAQ: Can I change the configuration to enable Long Range (LR) Mode in an AC/CL 4490 that is not an "LR" model?

The Long Range (LR) variant of the 4490 series adds a Low Noise Amplifier (LNA) which increases receiver sensitivity ~10dB when enabled. The non-LR variants of the 4490 do not contain the additional hardware and as such do not support LR mode.
