Basic Steps for Recording EEG Patient Hookup with Recording Cap 1. Scrub the patient's ears and forehead with Nuprep and wipe off with an alcohol swab. 2. Measure the circumference of the patient's head in order to choose the right recording cap: Green (47-51 cm) Yellow (51-55 cm) Red (54-58 cm) Blue (59-63 cm) 3. Put the cap on the patient's head with the tag in the back. • Make sure FZ, CZ, PZ are centered. • Make sure that CZ lines up with the ears. 4. If using ear electrodes, place tin ear clip electrodes, filled with gel, onto the patient's ears. 5. If using ear electrodes, plug ear electrodes into ear sockets in cap, or if cap does not have ear connectors, plug into A1 and A2 sockets on Headbox. 6. If the recording cap is not a Deymed brand cap, place a ground electrode, filled with paste, onto the patient's forehead in the center of FP1 and FP2, and plug the electrode into the green 'PG' slot on the TruScan Headbox. 7. Plug the cap into the Headbox via the 25 pin connector, preferably using the included wear and tear extension cable to protect the Headbox connector from overuse. 8. Put gel into every hole in the cap but be careful not to overfill. If gel runs down from one electrode to the other, they will short and the signal will be disrupted. 9.Make sure that all of the impedances, including the ground, are below 10Kohm or show as Blue or Green on the impedance display. If any channel is not showing Blue or Green, then the connection is most likely not low enough and precaution should be taken to further lower the impedance. TIP: Take the end of the wooden Q-tip and twist around in the corresponding hole on the cap for the problem electrode. You can also add more gel if necessary while being careful not to overfill. Software Setup and Recording 1. From the Edit Patient's Card tab, add a new patient. Fill in the name fields. Give the patient an ID number. 2. Set the montage to the preferred montage* (on the left side on the screen next to the record and stop buttons) 3. Set the sensitivity to 70µV to start. You may reduce or increase this to facilitate a better visualization of the brainwaves during the recording. Note that this setting does not affect the actual stored data. 4. Hit record when the patient is ready with his or her eyes closed and still. If the patient needs assistance keeping his/her eyes closed then place your fingers over his or her eyes. 5. Look for EMG and movement on the recording and, if necessary, pause and coach the patient. 6. After 10 minutes of recording hit stop. 7. The Patient may now be disconnected and cleaned up. You may now exit the TruScan software.

In the left panel, a user can control the recording and change recording settings. The controls include the record, pause and stop buttons. Other settings or control buttons include the time base, sensitivity, filters and montage controls. However, none of these recording settings will affect the actual recorded signal if changed during recording. All signal is recorded to its full bandwidth according to the sample rate set on the 'Recording System' page. The number of channels recorded is also set on the 'Recording System' tab. Click here for more information on the 'Recording System' settings. For more in-depth details on this panel, go to Left panel section of this user manual.
Signal screen The EEG will appear in this main signal screen. Labels for each channel are shown including the active and reference channels for each signal. At the end of each line, the sensitivity setting is displayed. Yellow lines are shown in place of signal if the impedances are not below 50 KOhms. This helps the user identify when there is a good connection and also helps make it obvious in the event that any electrodes lose contact during recording. This feature can be turned off in the recording system tab by turning off the "impedance check" option.
