Provides an easy to setup means of preventing electrosurgical artifact from contaminating EP responses and EMG recordings. Attach the clip to the lead wire of electro-surgical tools and turn on the options in the Cascade software. One clip will handle multiple tools but when two electrosurgery units are in use, two clips may be used with a single module. The module plugs into the auxiliary port on the base of either Cascade or Cascade Elite. Clips are sold separately.
