Low Pass Filter
: To decrease unwanted high-frequency signals which cause hissing and background noise,
press the (-) while the transmitter is in the lock mode to adjust the level of filtering from (1-8).
(1 being the
lowest filter setting and 8 being the highest filter setting)
. The display area will go blank once you scroll past
8, which indicates the filter is disabled. The system will automatically start at 1 once you scroll past the blank
screen.
Note: A low-pass filter is a filter that passes low-frequency signals but attenuates signals with frequencies
higher than the cutoff frequency. The purpose of adding this into design is to block high pitches which cannot
be efficiently broadcast.
