3 Operating Instructions EP15/EP25

1. All contact between the conductive parts of electrodes or their connectors, including the neutral
electrode and other conductive parts including the earth must be avoided.
1. Please check the setup before recording, and verify that the correct type of sound stimulus, level,
filtering, and recording window will be used as another operator/person may have changed/deleted
the protocol setting. During recording, the stimulus parameters can be seen on the user interface.
2. If the system has not been used for a while, the operator should inspect the transducers (e.g., check
the insert phone silicone tubing for cracks) and electrodes (e.g., check the expiry date of disposable
electrodes, check cables for damage) to verify that the system is ready to start testing and provide
accurate results.
3. Only electrode gel intended for electroencephalography must be used. Please follow the
manufacturer's instructions regarding the use of the gel.
4. Contraindications to placing an insert earphone in a patient's ear include a discharging ear, acute
external auditory canal trauma, discomfort (e.g. severe otitis externa) or occlusion of the external
auditory canal. Testing should not be performed on patients with such symptoms without a medical
doctor's approval
5. The presence of tinnitus, hyperacusis or other sensitivity to loud sounds may contraindicate testing
when high intensity stimuli are used.
1. The Eclipse system consists of a 2 channel input board which allows the user to create
measurements for both ears without switching the electrodes.
2. In the case of tense patient muscles, particularly in the region of the neck, nape and shoulders, the
quality of the recordings may be poor or completely rejected. It may be necessary to reinstruct the
patient to relax and then resume testing when the muscles have relaxed.
3. The digital filters of the EP system may help the operator to filter out an unwanted signal to a certain
extent.
4. The operator may benefit from watching the Raw EEG bar and modifying the Preamplifier filters
located in auto protocols setup to improve the quality of the measurement. The filters may be
modified prior to or during a recording.
