ncluded with each Net are a number of replacement kits. Additional kits are
available from EGI.
The GSN 200 comes with five electrode-replacement kits, and the HCGSN is provided
with 10 replacement sponges. These are the only parts that can be serviced by the user;
all other repairs must be performed by EGI. For instructions on replacing sponges, see
page 97.
Replacing Electrodes (GSN 200)
Each electrode-replacement kit contains a new electrode consisting of a unitized
sponge, electrode pellet, lead wire, and integral Hypertronics contact. The kit
(Figure 9-1) does not contain a pedestal because the replacement process uses the
existing pedestal of the sensor that is receiving the new electrode.
