Using the lab's stimulator, stimulate to each of the four inputs to
ensure that the amplifier recognizes the stimulus. If no stimulator is
available, connect the 2 mm pins from your stimulator to each of the
stim inputs one at a time. Output a signal of at least.3 V and make
sure the signal appears on each of the stim channels as you connect
it.
In the Real-Time window, select the Administration menu and select
Amplifier Test.
Choose Register readback and perform the readback function. The
values sent should be the same ones as the ones received.
Click on the walking ones tab and perform the walking ones test only
once. Make sure there are no errors during the test. Errors imply
communication problems with the channels.
Select the Stim Walking Ones tab and perform the test once. Once
again, there should be no errors.

Disconnect and properly store any patient cables.
