After the initial charge, regular charging time is approximately 4 hours. The LED light on the adapter (not the soles!) turns to red during loading and then to green after loading is completed! After the soles are fully charged, unplug the adapter and the soles. The THERMO SOLES are now ready to be used! If for any reason the charger detects irregularities during charging, the safe charge function will be activated, resulting in an increase of the charging time. The high-quality 1,000mAh LI-ION Polymer Batteries (no memory effect!) can not be damaged by frequent charging and can be re-charged approximately 500 times!

CUTTING TO SIZE INSTRUCTIONS:
The soles are constructed in such a way, that the size can be trimmed to fit if needed! Please be sure to follow the WARNING statement printed on the bottom of the soles! The two cutting lines are for reference only! Please note that the THERMO SOLES cannot be exchanged, if they were trimmed.

CAUTION:
Do not cut beyond the solid line or excessively bend the soles! This will cause damage to the heating elements and the product!

CARE INSTRUCTIONS:
 

• Turn OFF the soles when not in use.
• Store the soles and adapter in a clean and dry place.
• Only use the enclosed original adapter to charge the soles.
• Only charge the soles when they are outside of your shoes or boots.
• Do not damage the heating elements by bending the soles.
• Charge only under supervision and place batteries on a non-flammable base, away from any flammable materials, fire or warm objects.
• Cut the soles to size only as mentioned above!
• Clean with a damp cloth only!
• Do not submerge in water!
• Air-dry the soles only! Do not place them on radiators or any other hot surface!
• Let the soles dry completely before charging again.
• The switch must be set to the “OFF” position when charging the soles.
• Should the switch be set to the “ON” position when charging, the soles will NOT be charged! In this case, please disconnect the soles from the adapter cables, turn the switch a couple of times to the “ON/OFF” position and then set it to “OFF” before
  connecting the soles to the adapter cables again. The temperatures are measured directly at the heating elements.

HELPFUL INFORMATION:
 

• Please perform the following test in case you feel that the soles are not heating correctly:
• Charge the soles completely (switch to the left!)
• Both soles always must be charged at the same time!
• Now turn ON the soles (switch to the right!) and the LED light on the soles will light up!
• Place the soles in the refrigerator for about 5 – 10 minutes.
• Check the LED lights of both soles after taking them out of the refrigerator again.
• If the light is ON, then the soles are in the heating mode and you should feel the warmth on the upper and lower sides of the soles with your hands or your cheek.
• The LED lights will turn off again after about 2 minutes. (As explained above!)

• Hold the heel of the soles and pull the tab below the USB port down.
• This will separate the bottom black fabric lining from the top portion of the soles.
• Cut open the insoles at the heel area and remove the black plastic case protecting the batteries.
• Separate the plastic case in order to reach the batteries.
• Cut the cables and remove the batteries.
• Discard the batteries separately from the soles.
