| <note>LED, DS1 from CN0534, will automatically turn on indicating that the CN0534 is powered and operational. If the LED is off, the CN0534 could still be powered properly, but the RF input power into the amplifier might be activating the automatic shutdown, so try to lower the RF input signal by 10dB and see if the LED turns on.</note> | <note>LED, DS1 from CN0534, will automatically turn on indicating that the CN0534 is powered and operational.
