FHC Guideline 4000 LP+ Directions For Use Manual page 10

B. If using the microTargeting Controller and motor or encoder, connect the microTargeting motor or encoder assembly as
shown and perform the following steps:
1. Zero the microTargeting Controller by pressing the small black button on the front panel of the Controller.
2. The depth readout of the microTargeting Controller should appear on the computer screen. If it does not ("MTC not
detected!" appears when hovering the cursor over the gray exclamation point on the electrode tab), check that the encoder
or motor assembly and remote control are properly connected. Click "Settings", select the "mT Controller" tab, and verify that
pressing the "Reset" button resets the microTargeting Controller. If it does not, or if the "Reset" button is inaccessible,
reassign the COM port for the Controller.
3. If using the motor, advance the drive towards the target by turning the remote control knob clockwise. Pressing the
"Retract to Zero" button on the remote control will retract the drive to zero.
4. If using the encoder, the drive must be manually advanced. Do not use the encoder with the remote control.
C. If desired, change filter, gain, and LFP settings by clicking the "Electrode Settings" button on the computer screen. Change
software preferences by clicking the "Settings" button on the computer screen. Remember to update the current user
profile to save changes.
D. Check electrode impedance by clicking the "Impedance Check" button on the computer screen and pressing the orange
activate button on the stimulation remote control.
E. Record events using the "Event/Recording" (for single channel recording) and "Record All" buttons (for multi-channel
recording) or by right-clicking on the channel thumbnails on the "Electrode" tab.
F. Click the "Stimulation" button on the computer screen to enter stimulation mode. Select either "Microstim or
"Macrostim" from the pull-down menu. Control stimulation amplitude using the knob. Start/stop stimulation using the
orange activate button on the stimulation remote control. If desired, stimulation may be stopped by pressing the orange
activate button again (during fixed-duration mode only).
WARNING: Electrodes and microelectrode cables are single-use items. Do not attempt to sterilize and re-use. Dispose of
electrodes according to hospital protocol.
WARNING: Use of non-supported electrodes can result in poor quality recordings, incorrect stimulation, inaccurate targeting, or
patient injury.
WARNING: Electrodes and electrode cables should be connected one at a time. Be careful to assign electrode tracks and
electrode contacts correctly.
WARNING Route electrode lead cables carefully to avoid a tripping hazard or possible contamination of the sterile field.
WARNING: Never leave a microelectrode cable connected to the Guideline 4000 LP+ if it is not connected to an electrode.
WARNING: Do not connect the electrode cables to earth.
WARNING: Auxiliary inputs are provided to monitor additional biological signals. Do not rely upon the auxiliary inputs as the sole
means of tracking vital signs.
WARNING: The auxiliary inputs and outputs are not isolated. Do not make direct connections between the auxiliary
inputs/outputs and the patient.
WARNING: Always adhere to the electrode manufacturer's recommendations with regard to the maximum amount of
stimulation current applied.
WARNING: Do not attempt to use the Guideline 4000 LP+ stimulator to create lesions.
WARNING: Never touch electrode cables while stimulating.
WARNING: Use caution when electrically stimulating a patient with existing implanted electronic devices.
WARNING: Monitor the patient for adverse effects during electrical stimulation.
WARNING: Always remove any electrodes prior to using high frequency surgical equipment. Failure to do so could result in burns
at the electrode site and possible damage to the Guideline 4000 LP+ .
WARNING: Cables are not defibrillator proof and must be removed prior to defibrillation.
WARNING: To prevent the risk of shock, all electrode and electrode leads should be disconnected from the patient before
defibrillation. The Guideline 4000 LP+ is not defibrillator proof.
