NFORMATION
The Freedom SCS System uses wireless technology to program the WAA
Programmer and to power the stimulator. The WAA Programmer is
programmed utilizing a Bluetooth® data communication protocol. Bluetooth® is
used only during programming sessions and only by a trained clinician. Various
programs are stored in memory within the WAA Programmer, which can be
selected as needed. The WAA Programmer communicates with the Stimulator
using a pulsed radio frequency signal centered at a frequency of 915 MHz.

Quality of Service
In order for the Freedom SCS System to
operate, the WAA Programmer should be
centered over the Stimulator within 0.8
inches or 2 cm. To better ensure proper
function, the WAA Programmer should be
worn in the same position as when it was
originally fitted. When the wireless link
between the WAA Programmer and
Stimulator is broken, stimulation will cease.
The wireless link may not function in the
presence of large magnetic or radio fields.
