Frequently Asked Questions - Heat Pack 2.0 LENZ

How do I charge my LENZ Heat Pack 2.0?

Connect the USB cable to the Charge Box and a 5V/1A USB power supply. Place both heat packs in the Charge Box with correct orientation. Charging starts automatically; the LEDs show progress. When all LEDs go off, the packs are fully charged.

How long does it take to fully charge the heat packs?

The charging time is approximately 7-8 hours. Always charge after each use to extend battery life.

How do I turn on the heat pack and adjust the heat level?

Briefly press the control button (about 0.5 seconds) to turn on at the lowest setting. Press repeatedly to cycle through low, moderate, and high heat levels. Press again to turn off.

What do the LED indicators on the heat pack mean?

The heat setting display shows the three heat levels by flashing. To check the charge level, press and hold the control button for at least 2 seconds; the LEDs indicate low, medium, or high charge.

Can I use the Heat Pack 2.0 with any LENZ heated product?

Yes, the heat packs are designed for use with compatible LENZ heat products (textiles, socks, etc.). They connect via snap fasteners until they audibly lock into place.

Is it safe to fall asleep with the heat packs on?

The manual warns not to operate the device at the highest heating level for longer than several minutes. For comfortable warmth, select a low or medium heat level so the heating is nearly unnoticeable. If you have sensory or circulatory conditions, consult a doctor first.

How should I store the heat packs when not in use?

Store them in a cool room in a half-charged state, with the contact protectors attached and the packs switched off. Disconnect the USB power supply from the Charge Box if they remain inside.

Can I clean the heat packs with water?

Clean the parts as needed with a soft, slightly damp cloth and a mild detergent. Always disconnect the USB power supply from the socket before cleaning. Do not immerse in water.

What safety functions does the Heat Pack 2.0 have?

It features short-circuit protection, overcharge protection, and exhaustive discharge protection via integrated electronics. The battery packs stop charging outside the allowed temperature range and blink an LED.

How long does the battery last per charge?

The heating period depends on the selected heat setting, ambient temperature, battery age, and charge state. See the product packaging or www.lenzproducts.com for the exact heating power and period table.

FIRST USE AND CHARGING

Important note:

The battery packs must be charged before using them for the first time.

Charging procedure

1. Connect the USB cable (Fig. 2.1) to the Charge Box (Fig.
   2.2) and a USB power supply unit (5 V, 1 A, not included in delivery) and plug the USB power supply unit into a socket.
2. Place both battery packs into the Charge Box (Fig. 2.2). Please check the illustration on the Charge Box to ensure proper orientation. The battery packs can be charged in any operating mode.
3. The charging process starts automatically.
4. The charge indicator (Fig. 1.2) shows the progress of the charging process as it slowly rises.
5. Once the battery packs are fully charged, the charging process ends automatically and the charge indicator LEDs (Fig. 1.2) are switched off.
6. After the end of the charging process, please remove both battery packs from the Charge Box. (Fig. 2.2)

Important note:

- If an attempt is made to charge the battery packs outside of the specified ambient temperature range (see safety precautions), the charging process will be prevented automatically and this will be indicated by

the lower LED on the battery packs blinking. Disconnect the battery packs from the Charge Box and restart the charging process at room temperature.

□□□ LED blinkiing – Temperature error

• Charge the product after every use. This helps extend the life of the battery packs and ensures that the product is ready for use at any time.
  ■ The battery consists of lithium ion cells and can be charged in any state.
• For this reason, the battery does not need to be fully discharged before charging.

Charging time

HEAT SETTING - HEATING PERIOD

For heating power and heating period data, please see the table on the product packaging. You can also access the data online at www.lenzproducts.com

The heating period per charge depends on the selected heat setting, the ambient temperature, the battery packs, and the charge state as well as the age of the battery packs

SERVICE, STORAGE AND CARE

Storage mode

The storage mode half charges the battery packs and then puts them to sleep, so your battery packs can be stored in perfect condition.

1. The battery packs must be discharged to start the storage mode. If needed, discharge the battery packs using your heating product.
2. Start the charging process as usual (see Charging process)
3. To start the storage mode, press and hold the control button (Fig. 1.3.) for 3 seconds. All three LEDs of the charge indicator will blink three times.
4. The first two LEDs of the charge indicator (Fig. 1.2) show

the increasing progress of the charging process.

1. Once the battery packs are half charged, the charging process ends automatically and the charge indicator LEDs (Fig. 1.2) are switched off.
2. After the storage mode has finished, store the battery packs as described in "Storage".

Important note:

- If the battery packs are more than half charged, the storage mode will automatically be prevented, and this will be indicated by the middle LED on the battery packs blinking. Disconnect the battery packs from the Charge Box and connect them to your heating product to discharge them. Afterwards, restart the charging process and the storage mode.

LED blinking - Error

Storage

To ensure long battery life, we recommend storing the battery packs in a cool room (see safety instructions) in a half-charged state. The battery packs must be turned off (heat setting display (Fig. 1.2) dark) and disconnected from the heatable textile for storage. They can remain in the Charge Box for storage, but to do this, disconnect the USB power supply unit from the Charge Box.

For long-term storage, the battery packs must be discharged and recharged halfway at least every 6 months. This ensures that maximum performance is preserved for many years!

Caution: Always store the battery packs with the contact protector attached!

Cleaning

Clean the parts as needed with a soft, slightly damp cloth and a mild detergent.

Caution: Always disconnect the USB power supply unit from the socket before cleaning.

DISPOSAL

• Once the product has served its purpose, please dispose of it and its packaging appropriately and in an environmentally friendly manner.
• Please do not dispose of the charger together with the household waste. Instead, bring the parts to a collection site for electronic waste. (d)
  ■ Take the battery packs to the intended collection sites for used batteries. (d)
