  • Do not put on or use wet Heat Socks XLP ONE.

2.5 Warning of burns

Heat Socks XLP ONE can cause burns. The higher the temperature setting, the higher the risk of burns. The user is responsible for the following:

  • Using Heat Socks XLP ONE as instructed.
  • Being aware of his/her personal sensitivity to heat and susceptibility to burns.
  • Knowing his/her own early warning sensations of a burn.
  • Removing his/her feet from the heat source before a burn is suffered.
  • Never using heat setting 4 for longer than three minutes successively. Heat Socks XLP ONE can become too hot for continuous use on this heat setting and may therefore cause burns.
  • Contacting a doctor before using the Heat Socks XLP ONE if he/she suffers from a physiological condition or is taking medication or drugs which increase skin sensitivity or reduce the skin's sensation to heat. Such a physiological condition or medication could increase the risk of burns. Examples of physiological conditions and medications which can increase skin sensitivity or reduce the skin's sensation to heat are calluses on feet, diabetes, heart or circulation problems, nerve system disorders, Raynaud's syndrome and tetracycline. There may also be other physiological conditions or medication which increase skin sensitivity or reduce the skin's sensation to heat.
  • Not waiting until his/her feet are cold before increasing the heat setting. Cold feet reduce the skin‘s sensation to heat and therefore increase the risk of burns.
  • Not using damp or wet Heat Socks XLP ONE as the heat transfer is increased by moisture and the risk of burns therefore increases.
  • Never using Heat Socks XLP ONE when under the influence of drugs or alcohol as this can increase skin sensitivity and/or impair the ability to recognize the early warning sensations of a burn. Drugs and alcohol can increase the risk of burns.
  • Not using Heat Socks XLP ONE when sleeping.

The early warning sensation of a burn are:

  • A particular part of the foot becoming hot.
  • A certain part of the foot feeling as if you are standing on a small stone or a sharp object - no matter whether you can feel heat or not.
  • The colder the feet are, the more intense the feeling and sensation might be.
  • The early warning sensations of a burn may differ from person to person.

In the event of a malfunction, see chapter 3.4, Malfunctions and special functions, page 6.

3.4 Malfunctions and special functions

Trickle charging at low discharge level

When the Battery Packs XLP ONE is allowed to discharge too low (voltage lower than 2.7 V), trickle charging is activated. In this proces, all of the heat setting LEDs flash semi-quickly (every 0.3 seconds) for a maximum of 30 minutes.

If the trickle charging process is successful, it switches back to normal charging process. If there are any persistent problems after 30 minutes, then all the LEDs start to flash quickly (every 0.1 seconds) and indicate the charging process will not work. Remove the Battery Pack XLP ONE from the charging cradle.

High level short circuit protection

The Battery Pack XLP ONE switches off in the event of a high level, external short circuit. Once the short circuit is eliminated, the Battery Pack XLP ONE must be reset by connecting it to the Recharger XLP.

Low level (HICCUP) short circuit protection

In the event of a low level, external short circuit (HICCUP short circuit), all the LEDs flash quickly (every 0.1 seconds) for five seconds followed by an internal check to identify whether there is still a short circuit. If the short circuit remains, the LEDs continue to flash quickly (every 0.1 seconds) followed again by an internal check. This process remains until the short circuit is remedied. Once the short circuit has been solved, the heat setting being used is reactivated.

Charging temperature

In case of inappropriate temperature of the Battery Pack XLP ONE (see chapter 8.1, Technical specification, page 11), the charging process is aborted and all the LEDs flash quickly (every 0.1 seconds) until the Battery Pack XLP ONE is removed from the charging cradle or the Recharger XLP is disconnected from the plug socket.

Charging time monitoring

If the charging process takes an unusually long time, this may lead to a safety shutdown. The charging process is aborted and all the LEDs flash quickly (every 0.1 seconds).

Info Important information:

  • Charge the Battery Packs XLP ONE after each use. This extends the life of the batteries and ensures the product is always ready to be used.
  • Frequently overcharging (more than 8 hours) the Battery Packs XLP ONE can cause reduced performance and/or service life.
  • Battery Packs XLP ONE consist of lithium-ion batteries and can be charged in any condition. This means it is not necessary to let the battery run down completely before charging it.
  • Battery Packs XLP ONE must not be charged if the battery temperature is below 10°C. You should therefore store the XLP ONE battery packs at room temperature (+20°C/+68°F) for a few hours before charging.
  • Before putting the Battery Packs XLP ONE into storage for a long time (several months), they should only be half charged (1st and 2nd LEDs light up red and 3rd LED flashes slowly) in order to increase the service life.
  • If stored for a long time (several months), the Battery Packs XLP ONE must be recharged before use.
  • The Battery Packs XLP ONE should be stored switched off (all the LEDs off) and disconnected from the Recharger XLP and from the Heat Socks XLP ONE with the contact protection covers attached.

4 Control and operation

4.1 Putting on Heat Socks XLP ONE

  • Pull on the Heat Socks XLP ONE.

Info To ensure your HEAT Socks XLP can be used for a long time, be careful when putting them on. The main cause of damage to the fabric of Heat Socks XLP ONE is snagging on rings, fingernails or toenails.

Info Make sure that you wear the correct heated socks on the right and left. (The socks are marked L/R; the rechargeable battery is attached at the top on the outside of your shin!)

Putting on Heat Socks XLP ONE

A: Insert your hand into the sock and grip the foot section by the bulge on the heel.

B: Hold the sock in both hands, and gather the sock so that you can easily insert your foot up to the toe of the sock.

C: Gently pull the sock up over your heel, avoiding creases, and along your lower leg up to your knee.

Once you have put on the sock, gently smooth the sock with your hands, working from the bottom up until it
fits snugly against your leg. Never pull up the sock by its ends. This can cause the sock to gradually stretch, slip or crease. Once again: never pull on the sock ends!

Info Do not use the Heat Socks XLP ONE without footwear as this may cause damage to the integrated Heating Elements!

  • Push the Battery Packs XLP ONE onto the Heat Socks XLP ONE's 3 snap connectors until they audibly engage. It does not matter whether the power button is facing forwards or backwards.
  • Select the desired heating setting (see chapter 4.2, Operating settings for Battery Packs XLP ONE, page 8).

Warning! WARNING! - There is a risk of burns!

Do not leave the highest heat output on for more than a few minutes as the heat generated can cause burns! (see chapter 2.5, Warning of burns, page 4)

4.2.3 Rapid discharge function

Rapid discharge function

The rapid discharge function is only to be used to check whether the Battery Packs XLP ONE and Heat Socks XLP ONE are working correctly.

  • Attach the Battery Packs XLP ONE you want to check to the 3 snap connector on the Heat Socks XLP ONE.

Warning! WARNING!

The rapid discharge function must not be used to warm up feet as the Heat Socks XLP ONE can get very hot and this can cause burns (see chapter 2.5, Warning of burns, page 4).

  • Set to heat setting 4 (see chapter 4.2, Operating settings for Battery Packs XLP ONE, page 8).
  • When all four of the LEDs light up, press the power button for 5 seconds.
  • At 5 seconds, all four LEDs will flash simultaneously and slowly. To end the rapid discharge process, press the power button.
    • for 0.2 second to return to heat setting 1.
    • for 2.5 seconds to switch the Battery Packs XLP ONE to OFF.
  • Also, the Battery Packs XLP ONE automatically switches to OFF when fully discharged.

4.3 Using the Heat Socks XLP ONE

The Heat Socks XLP ONE help keep your feet warm. Do not let your feet get cold first. Warming up cold feet uses more energy, is less effective and is not the way the Heat Socks XLP ONE should be used.

Set the heat setting to 1, 2 or 3 before going into the cold to help keep your feet warm.

Set the Heat Socks to heat setting 4 for an extra burst of heat, also known as „Boost Setting 4“. Heat setting 4 automatically switches back to heat setting 3 after three minutes.

4.4 Tips for using the Heat Socks XLP ONE

It may be necessary for people with extremely poor circulation or during very cold weather to use heat setting 2 or 3 as the default setting in order to prevent feet from getting cold. If this is the case, an extra pair of Packs XLP ONE may be helpful to ensure warm feet for the whole day.

Do not let the chair lift hit you! Otherwise you could sustain an injury or damage your Battery Packs XLP ONE.

Choosing the right boot size is important in order to help keep your feet warm. Boots that are too tight obstruct good circulation and may reduce your comfort and warmth.

Dry boots, dry socks

  • If your boots are wet, your feet will get cold too.
  • Wet conductive heat loss is 23 times greater than dry heat loss. (W. L. Gore & Associates, 1994).
  • Keep your boots dry! Dry after each use! Every day in which moisture is allowed to collect makes the task of keeping feet warm more difficult. A shoe dryer may be advisable in certain circumstances (e.g. Hotronic's Snapdry Boot & Glove Dryer).
  • Take out the liners so that the space between the insole and the shoe shell can dry properly.
  • Keep the Heat Socks XLP ONE clean and dry!

4.5 What to expect of heat settings

  • Expect imperceptible heat to maintain your comfort and warmth.
  • Do not expect to feel “fireplace toes”.
  • Learn what personally works best for you over time.
  • Think of your Heat Socks XLP ONE as Thermo Active Insulation (TM). As the cold penetrates through your insole, it draws heat off the Heating Element rather than your toes. Balanced heat is imperceptible yet maintains your comfort and warmth. Too much heat and your feet feel excess heat. Too little heat and your feet feel the your cold penetrating through.
  • If feet are comfortable yet you feel excess heat, then turn to a lower setting to minimize perspiration and maximize the battery duration.
  • If your feet begin to feel cool, then turn the setting up to maintain comfort and warmth.
  • If you think your Heat Socks XLP ONE are not working, try turning the left Battery Pack off. If your left foot becomes colder, your Heat Socks XLP ONE are working properly.
  • The ability to feel heat and maintain comfort and warmth depends upon: proper installation; type, fit, and dryness of footwear, sock, and insole; foot callus size; activity levels; weather conditions; and other factors.
  • Expect the bottom of your toes to feel heat less than your fingers and hands.
