Impulse Dynamics OPTIMIZER Lite System Patient Manual page 63

One illuminated bar indicates degraded QoS which may
require a longer charging time. Zero illuminated bars on
the Coupling Level icon accompanied by an audible
beeping tone indicates poor placement of the charging
wand. If the charging wand is not repositioned onto the
implant site within 20 seconds, the Vesta Charger will
emit 3 long beeping tones, display the Charging IPG
Coupling Error screen, and then shut off.
Besides charging the OPTIMIZER Lite, the Vesta Charger
also serves as a way of messaging the patient about
alerts and other conditions. The Vesta Charger is
configured to communicate with the OPTIMIZER Lite IPG
at least once a day. This communication occurs whenever
the IPG is within 5 ft of the Vesta Charger for a few
minutes.
If the Vesta Charger and the OPTIMIZER Lite IPG do not
communicate within a programmable time period, the
patient may see the "Long Time Without Downloading
Data From IPG" alert screen displayed by the Vesta
Charger:
In this case, instruct the patient to attempt to charge their
OPTIMIZER Lite IPG with their Vesta Charger. If the
patient is able to charge their implanted device
successfully, then the alert screen should no longer be
displayed by the Vesta Charger. If the attempt to charge
the OPTIMIZER Lite IPG with the Vesta Charger is
unsuccessful, please call the 24-hour Support Hotline
(866-312-5370).
