Check the expiration date on OneStep electrodes, and 
replace them if they are expired.

OneStep electrode condition sensor indicates that the 
electrode gel has dried or aged beyond its specifications. 
The electrodes may no longer provide optimal therapy. 
Replace therapy electrodes. (If emergency defibrillation is 
required and spare hands-free therapy electrodes or 
paddles are not immediately available, it may be advisable 
to use the pads in question rather than delay therapy.)
