12.6 Turn gammaCore Sapphire CV on by pressing
412
the power button. When the device is ready for
413
use, the device will beep once. The number of
414
stimulations available for that 24-hour period
415
and months/days remaining will be displayed.
416
417
418
12.7 Position the device on the side of the neck
419
over the treatment location. Use mild to
420
moderate pressure so the device makes good
421
contact with the skin; however, do not apply
422
excessive pressure to the neck.
423
424
425
426
12.8 Increase the intensity level by repeatedly pressing the top area of the control button to the
427
maximum level you can tolerate. Once you have found your maximum level, hold gammaCore
428
Sapphire CV in place for the remainder of the 2-minute stimulation. The device will beep every
429
time the control button is pushed, and the display will indicate a numerical value between 1 and
430
40, which signifies the intensity level. You will likely feel muscle contractions at the treatment
431
location. These muscle contractions are normal and should stop after the stimulation is
432
complete. The appropriate intensity level is different for every person and may vary from
433
stimulation to stimulation. For the majority of individuals, the appropriate level of stimulation will
434
be between 15-25 on the numerical display.
435
436
NOTE:
Neck muscle contractions during the stimulation that are not painful are normal and
437
not a reason to stop the stimulation. If muscle contractions are too strong or uncomfortable, try:
438
439
•
Removing gammaCore Sapphire CV from the neck.
440
•
Lowering the intensity level by pressing the bottom area of the control button.
441
•
Repositioning gammaCore Sapphire CV on the neck over the pulse and slowly
442
increasing the intensity level again by pressing the top area of the control button.
443
444
If the stimulation is still intolerable, turn the device off by pressing and holding the power button and
445
discontinue the stimulation.
446
CAUTION:
Do not turn gammaCore Sapphire CV on again until preparing for the next treatment. The
447
device has a limited number of stimulations it can deliver.
