12. FCC Information

Changes or modifications to the product not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
Note:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in ac-
cordance with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interfe-
rence to radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
Possible cause/remedy
1. Ensure that the batteries are inserted correctly and have contact. The
on/off button must be pressed and held down to switch the unit on.
2. If necessary, replace the batteries.
3. Please contact customer service.
1. Increase the pulse intensity incrementally.
2. Press the on/off button to restart the program.
3. The batteries are almost empty. Replace them.
The electrodes are poorly moistened. This can lead to skin irritation, as
the current is no longer distributed evenly over the entire surface. Switch
off the unit. Take off the belt, moisten the belt (electrodes) and your lower
back and restart the program according to the manual.
Discontinue the treatment immediately and wait until the skin returns to
normal. Temporary skin reddening under the electrode is harmless and
is a result of increased blood flow. However, if the skin irritation persists
and you feel itching or irritation, consult your doctor before continuing
use.
