(120
Hz
cutoff
installation)
e) SERVICE, to update the firmware (use the
proper USB-port (1) for this operation)
f) S1 - LOUDNESS, for a low-frequencies
enhancement, in case of installation on a pole
stand
g) S2 – HF BOOST, for a high-frequencies
enhancement, in case of installation on a pole
stand
h) S3 – HF REDUCTION, for a high frequencies
reduction, in case of installation on a pole
stand
4 – Switch on the monitor
Connect the power supply (6) and turn the
