Vesta Charger Placement When Not Being Used For Device Charging; Frequency Of Charging Sessions - Impulse Dynamics OPTIMIZER Lite System Patient Manual

7.9 Vesta Charger Placement When Not Being
Used for Device Charging
Whenever your Vesta Charger is not being used to charge your
OPTIMIZER Lite IPG, it should be placed in an area frequented by
you (e.g., bedside table in your bedroom), connected to its AC
Adapter, and the AC Adapter plugged into the wall outlet. This will
keep the battery of your Vesta Charger fully charged as well as
ensure regular communications between your OPTIMIZER Lite
IPG and your Vesta Charger.
Note: Keeping your Vesta Charger continuously connected to its
AC Adapter while it is plugged into the wall outlet will not in any
way harm or weaken the battery in your Charger.

7.10 Frequency of Charging Sessions

The optimal performance of the rechargeable battery in your
OPTIMIZER Lite IPG can only be ensured if the battery is fully
recharged every week. It is not important which day or what time
you choose to charge your OPTIMIZER Lite IPG, but it is
recommended that you do not let more than seven days pass
between charge sessions.
If your Vesta Charger is not used to perform a charging session
on your OPTIMIZER Lite IPG within the time period set by your
doctor, you may see the Long Time Without Charging IPG alert
screen displayed by your Vesta Charger, indicated by an
animated image of the Vesta's Charging Wand being placed over
a patient's implanted device. See Figure 22.

If you see this message displayed by your Vesta Charger,

Lite IPG. If your attempt to charge your OPTIMIZER Lite IPG with
your Vesta Charger is unsuccessful, please call the 24-hour
Support Hotline (866-312-5370) as soon as possible.
If the battery voltage in your OPTIMIZER Lite IPG drops below a
certain level, CCM therapy delivery is automatically suspended. If
