Note: Improper positioning or displacement of the charging wand is indicated by the
corresponding a low signal strength on IPG-Charger Coupling Signal Strength
Indicator on the charger and by an audible signal sounding approximately once per
second.
Note: The charger will automatically discontinue the charging process if the charging
wand is not repositioned onto the OPTIMIZER Smart implant site. When this occurs, a
new charging process has to be initiated by pressing the Start Button again.
• The IPG Battery Status Indicator depicts the charging status of the
OPTIMIZER Smart IPG.
Note: Try to fully charge the device during the charging session. If the device cannot be
completely charged in one session, repeat the charging process, if needed in daily stages,
until the device is fully charged.
Note: Charging the OPTIMIZER Smart IPG can take longer than one hour if the battery
is severely discharged. The patient should be in a comfortable position while recharging
the OPTIMIZER Smart IPG, ensuring that the wand will be properly located over the
implanted IPG. This may be accomplished by draping the wand cable around the
patient’s neck so that the wand rests over the implant site. It is recommended that the
patient remain stationary during the charging process.
• When the battery of the OPTIMIZER Smart IPG is completely charged, a long
audible signal will sound and all 4 bars of the IPG Battery Status Indicator will
be illuminated. The charging process will then be automatically terminated and
the charger will shut off.
• To discontinue or suspend the charging process of the OPTIMIZER Smart IPG,
the patient can remove the charging wand of the OPTIMIZER Mini Charger from
the implant site, causing the interruption of the charging process. Alternatively,
the charger can be turned off by pressing the Start Button once again.
34.5 Frequency of Charging Sessions
Optimal performance of the rechargeable battery in the OPTIMIZER Smart IPG is only
ensured if the battery is fully recharged on a weekly basis. The day or time chosen to
charge the OPTIMIZER Smart IPG is not important, however it is recommended that the
patient not let more than one week pass between the charge sessions.
If the charge level of the OPTIMIZER Smart IPG battery drops below a certain threshold,
therapy delivery is automatically suspended. If this occurs, the OPTIMIZER Smart IPG
battery will need to be recharged before it resumes delivering therapy. Once the charging
session has been completed, the OPTIMIZER Smart IPG will automatically resume
therapy delivery with its previously programmed parameters.
