FHC Guideline 4000 LP+ Directions For Use Manual page 9

9. Select "Microstim" in the dialog box.
10. Select the appropriate channel in the dialog box. Verify that the test electrode is still plugged into this channel.
11. Set the stimulation amplitude to 100 µA. Set the pulse duration to 1000 µsec. Set the stimulus duration to fixed duration
and select 5 sec. Press the orange activate button on the remote control. Confirm that the software displays the warning
"Compliance Voltage Reached. " Confirm that the stimulus monitor tone is audible and set to a comfortable volume.
12. Switch to "Macrostim" mode.
13. Set the stimulation amplitude to 5 mA. Set the pulse duration to 1000 µsec. Press and hold the orange activate button on
the remote control to start stimulation.
14. Confirm that the current output is 5 ± 0.2 mA, the voltage output is 5 ± 0.5 V, and that stimulation stops when the orange
button is released.
15. Close the stimulation dialog box.
16. Verify the impedance check and stimulation functionality of each available channel (by repeating step 3B) before every
surgery.
WARNING: If an error occurs during the pre-use checkout procedure (step 3), discontinue use of the system. Contact an FHC
factory authorized representative for further instructions.
WARNING: Failure to properly perform the pre-use checkout procedure may result in patient injury or death.
WARNING: Disconnect the test electrode before connecting the LP+ to a patient.
4. Load a user profile and enter patient information.
a. Remove the test electrode if it is still attached to the LP+.
b. Click on the "Patient" tab at the top of the screen. Select a profile at the bottom of the screen. Click "Apply Profile" to load the
profile.
c. Click "Add New Patient" on the left-hand side of the screen to create a new patient.
d. Enter patient information in the fields provided.
5. Enter equipment and targeting information.
a. Click on the "Setup" tab at the top of the screen.
b. Enter equipment information and patient targeting coordinates using the fields provided.
WARNING: Incorrect equipment specifications could lead to errors in targeting or electrode depth.
WARNING: Using a non-supported drive, frame, or other device may result in incorrect targeting.
WARNING: Incorrect zeroing of the microTargeting Controller can cause serious injury or death.
WARNING: Incorrect specification of the initial target value can cause serious injury or death.
6. Perform microelectrode recording.
A. Connect electrode cables as shown in the diagram on page two. Connect electrodes and cables one at a time to avoid
confusion.
1. Assign an electrode to a channel using the Guideline 4000 LP+ software.
2. Check for a green light next to the channel on the Guideline 4000 LP+.
3. Connect the sterile electrode cable to the microelectrode, pass the DIN connector end out of the sterile field, and connect
the DIN connector to the correct channel.
4. Click on the "Electrode" tab at the top of the screen.
