Notes

1. If the TV function is not required, the tuner can be switched to power-down mode. In this mode the tuner reduces the

current consumption by up to 100 mA.

2. By this setting the FM radio AFC status can be read from the A/D bits in the status byte.

3. By this setting the RF input level can be read from the A/D bits in the status byte.
