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.

6. 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.
