2. WITH WHICH LENZ PRODUCTS ARE THE LITHIUM PACKS COMPATIBLE?

3. WHY IS THE LITHIUM PACK LED FLASHING EVEN THOUGH IT HAS BEEN TURNED OFF?

Batteries with production code* up to "21xx"
The blinking of the middle LED (every 2 - 3 seconds) signals the stand-by mode of the lithium pack. If you want to switch off the flashing during stand-by mode, you can activate the "LED OFF" function before exiting the Lenz heat app. After exiting the Lenz heat app, the LEDs on the lithium pack no longer flash.

The lithium pack still changes automatically after the in the Instructions for use specified time in the power-off mode.
The LEDs can be switched on again via the Lenz heat app or the LEDs will flash again as usual during the charging process.

Batteries with production code* from "22xx"
The flashing of the middle LED in stand-by mode has been deactivated.

*The production code is located on the back of the lithium pack and consists of four digits. e.g. "2107"

4. WHAT CAN I DO IF THE LITHIUM PACK WILL NOT SWITCH FROM STAND-BY MODE TO POWER-OFF MODE AND STILL BLINKING?

Batteries with production code* up to "21xx"

• Make sure that no heat sock/vest/bandage/gloves or charger is connected to the lithium pack.

8. What are the sizes of the heat socks / vests / soles / gloves?

9. How can the textile products (heat socks, heat vest/heat bandage/heat pants, heat glove) be washed?

10. For whom are heated textiles not suitable?

1. HOW DO THE HEAT SOCKS WORK?

The heat socks are functional socks with a proportion of merino wool. A heating element is integrated/sewn into these socks. The lithium pack is attached to the waistband of the socks with snaps. The sock waistband is folded over the lithium pack to fix it.

The heat output can be controlled via 3 levels on the lithium pack or steplessly via smartphone (with the lithium pack rcB 1200/1800).

2. WHERE DO THE HEAT SOCKS HEAT?

With the heat socks toe cap®, the heating element encloses the toes from above and below. This results in an optimal heat chamber for maximum comfort. We recommend wearing the socks directly on the skin. The heat socks therefore only heat up in the toe area, as it is always the outermost extremities such as the toes that get cold first when it is cold. When the toes are cold, the cold gradually spreads to the whole foot and the blood vessels that line the surface of the body constrict. If the toes stay warm thanks to the heat socks, the optimal circulation of the whole foot and leg is guaranteed.

3. WHAT IS THE DIFFERENCE BETWEEN THE HEAT SOCK 4.1 TOE CAP®, THE HEAT SOCKS 5.1 TOE CAP® (SLIM FIT) AND THE HEAT SOCKS 6.1 TOE CAP® MERINO COMPRESSION?

All heat socks with the addition "toe cap" have a heating element that encloses the entire toe area. This warms the toes from both above and below, creating an optimal heat chamber.

The heat socks 5.1 toe cap® have padding in the shin area and are suitable for all outdoor activities. The natural material mix of merino wool and silk supports the outstanding warming effect of the socks.

The heat socks 5.1 toe cap® slim fit are narrower in the forefoot area and are especially suitable for narrow feet and legs. They have padding in the shin area and are suitable for all outdoor activities. The natural material mix of merino wool and silk supports the outstanding warming effect of the socks.

The heat socks 4.1 toe cap® are the perfect companion for leisure and work in black. In the color green, these are the perfect socks for hunting and forestry.

The heat socks 6.1 toe cap® merino compression are the first heat socks with a toe cap® heating element, which are manufactured using compression knitting technology and a high proportion of merino wool. They are extremely thin in volume and are therefore ideal for all fitted and tight-fitting shoe types.

4. HOW DO THE HEAT VEST/HEAT BANDAGE WORK?

With the heat vest, the lithium packs are attached to the inside of the vest by means of press studs on the right and left and are not noticeable. The heat can be felt in the kidney and back area. The heat output can be controlled via 3 levels on the lithium pack or steplessly via smartphone (with the lithium pack rcB 1200/1800).

With the heat bandage, the lithium pack is also attached to a pocket on the front of the bandage using snap fasteners.

5. HOW DO THE HEAT GLOVES WORK?

The heat gloves have a pocket on the inside of the wrist in which the lithium packs can be stowed. The lithium packs can be connected to the heat gloves using the snap fasteners.

6. WHAT IS THE DIFFERENCE BETWEEN THE HEAT GLOVES 4.0 MEN/WOMEN/MITTENS UNISEX, HEAT GLOVES 5.0 URBAN LINE UNISEX AND THE HEAT GLOVES 6.0, 7.0, 8.0 AND 1.0 FINGER CAP ?

The heat gloves 4.0 heat the fingers on the temperature-sensitive upper side. Each finger is heated with an individual heating element. The gloves are designed for winter sports and can be used in a variety of ways. The heat gloves 5.0 urban line unisex are perfect for everyday use because they are thinner than the heat gloves 4.0 and 6.0 finger cap. They are therefore better suited for walking, cycling or for a trip to the Christmas market. The heat gloves 5.0 urban line unisex have the same heating element as the heat gloves 4.0 The heat gloves 6.0, 7.0, 8.0 and 1.0 with the addition "finger cap" are the gloves of the latest generation. They have a heating element that encloses the entire finger area and also heats parts of the back of the hand. This warms the fingers from both above and below. This creates an optimal heat chamber.

7. HOW DOES THE LED SYSTEM 1.0 WORK?

The connector plug is visible in the battery compartment of the LED system 1.0, the lithium pack is inserted into the battery bag provided.
The connector plug of the LED system 1.0 is connected to the push buttons on the lithium pack.
The flap is closed with the Velcro.
