Network Connectivity Problems
For an overview and step-by-step instructions to establish full network connectivity with the tablet, see
on page
If you are already logged in to the tablet and have lost network connectivity, first log off to return to
the login screen: return to the Start screen (see
on page
) and touch the
circle-X (exit) button at upper right, and then select

upper right.
Note: If you attempt to connect to a Wi-Fi network that requires you to go to an Internet website to
log in, as in some hotels and coffee shops, you will not be able to log in because the tablet does
not have an Internet browser program. As a medical device, its Internet connectivity is restricted
to the PDMS only.
Abnormal Lead Impedance (greater than 3500 Ohms or less than 250 Ohms)
Troubleshooting During an Intraoperative Procedure
The goal of the following procedures is to ascertain if the abnormal lead impedance measurement is
associated with the lead or with the RNS
®
Neurostimulator port to which the lead is connected.
1. Repeat the impedance measurements.
2. If the impedance remains abnormal, note the electrode label associated with the abnormal
impedance
3. Reconnect leads in the same neurostimulator port.
•
Disconnect and reconnect the leads to the connector cover and neurostimulator
according to the instructions in the relevant section of the system manual.
•
View the live ECoGs to verify that the signal is sufficient and without noise or artifacts.
•
Repeat impedance measurements.
4. If the impedance remains abnormal, note the electrode label associated with the abnormal
impedance.
5. Place leads in the opposite neurostimulator port.
