Quick-20m
This manual includes operating instructions, maintenance instructions, and
general information for use of the CGX Quick-20m.
Carefully read this manual to familiarize yourself with the headset, software, and
accessories before use.
Caution: Federal law restricts this device to sale by or on the order of a physician.
Description
The Quick-20m is a wireless, battery-
operated 10-20 montage EEG headset
utilizing dry sensor technology. The
headset provides an integrated
approach to the wireless acquisition of
EEG signals. A seated patient is free to
exhibit natural movements while real-
time data is collected.
The Quick-20m includes advanced
amplification and shielding to reject
ambient electrical noise.
The headset obtains high-quality
EEG with minimal scalp preparation.
Patented mechanisms and a range
of replaceable dry sensors align
to various head shapes and sizes,
maintaining sensor positions in a
standard 10-20 layout. EEG channels
are digitized with 24 bits of resolution
at 500 Hz. The Quick-20m is suitable
for general-purpose EEG.
