facing forward, align its center hole with the metal dowel and push down to attach securely.

TROUBLESHOOTING & MAINTENANCE
11. WHAT SHOULD I DO IF MY
issa
™
3 NOT ACTIVATING WHEN I PRESS THE UNIVERSAL BUTTON?
The battery may be empty. Recharge using the USB charging cable for up to 2 hours until fully charged, and then
restart your
issa
™
3 toothbrush by holding down the universal power button. Alternatively, it could mean that your
interface is locked and you will need to unlock it by holding down the + and – buttons together, after which the
indicator light will flash to indicate that your device is unlocked.
12. WHAT SHOULD I DO IF MY
issa
™
3 CANNOT BE TURNED OFF AND/OR THE INTERFACE BUTTONS DO
NOT RESPOND?
This could mean that the microprocessor is temporarily malfunctioning. Connect to the USB charging cable and/or
press and hold the universal button to restart the device.
13. WHAT DOES IT MEAN IF
issa
™
3’s INDICATOR LIGHT STOPS BLINKING WHEN THE USB CHARGING
CABLE IS CONNECTED?
This could mean one of several things. Either the battery is fully charged and ready for up to 365 days of brushing, or
the battery is drained and will require several minutes to acknowledge USB charging cable. Alternatively, it could mean
that the USB charging cable is not properly connected - check the electrical outlet / USB socket and charging port.
14. WHAT IF MY
issa
™
3 HAS FALLEN INTO WATER & THE CHARGING PORT IS WET?
issa
™
3 is completely waterproof and the charging port is fully sealed. So simply dry it off and continue use.
15. HOW WILL I KNOW WHEN TO CHARGE MY
issa
™
3?
When the indication light at the base of your
issa
™
3 turns red, it’s time to charge your toothbrush. Connect the
USB charging cable to any outlet for 2 hours. When the indicator light stops blinking, your
issa
™
3 is fully charged.
16. HOW DO I CLEAN MY
issa
™
3?
Clean the device after each use by washing the brush with warm water while running your fingers through the
bristles. We recommend using FOREO Silicone Cleaning Spray on the body of your
issa
™
3 and rinsing with warm
water afterwards for optimal results. Allow your toothbrush to air-dry. We do not recommend placing
issa
™
3 in a
UV sanitation case.
NOTE:
Never use cleaning products containing alcohol, petrol or acetone. Avoid using toothpastes with bleach on
your device.
