The available low-pass fi lter settings are OFF, 200 Hz, 1 kHz, and 2 kHz, but
the setting must be equal to the frequency range setting or lower. When the
OFF setting is selected, the low-pass fi lter is set to the cutoff frequency of the

available setting is OFF. For AC and CCLD channels, a 0.3 Hz high-pass fi lter
will apply even if the OFF setting is selected.
