1 General Description
SOLUM ESL Datasheet
Kaufland Label product is a part of the SOLUM Electronic Shelf Label (ESL) System, which includes Label, Gateway, and Remote Controller. The ESL System electronically displays customer content (i.e. price, product, and promotion information) on the Labels, which have traditionally been printed or written on paper in places such as retail markets and warehouses.
Kaufland Label wirelessly receives data from the Gateway and updates the display with the new information provided.
Kaufland Label is based on Bluetooth Low Energy (BLE) for low power wireless communication applications. It consists of an RF transceiver, RF circuitry and the ARM Cortex M3 MCU offering BLE based network protocol, MAC protocol and other peripheral devices.

4 Product Handling Precautions
SOLUM ESL Datasheet
Provisions should be made to protect against any damage to the product caused by improper handling. The purchaser assumes any responsibility for damage to the product caused by improper handling.
Product should be stored in 32F ~ 104F (0C ~ 40C) @45~70% RH environment and should be installed within 90 days of receipt.
4.1 Usage Environment
Take extra caution when using this RF device in the vicinity of other electronic devices and appliances. Most electronic devices and appliances use electromagnetic waves. Electromagnetic waves emitted by this RF device can affect other electronic devices and appliances.
If using the device in an explosion hazard area, follow all safety regulations, instructions, and signals.
4.2 Storage and Use
The product is shipped in sleep-mode (white screen), so it should be activated through NFC remote control or mobile app.
Moisture and liquids can damage internal parts and circuit boards if allowed to enter into the device itself.
Do not place or store the product on a sloped surface. The product may slide and fall off the surface and become damaged.
Use the product in temperatures ranges of 0 ~40 /32~104(BWRY), or -25 ~0 /13~32(Freezer). Parts and circuits may be damaged if operated or stored in extreme temperature.
The display panel needs extra care during handling.
– Do not apply any impacts on the e-Paper display as it is fragile. – Continuous exposure to excessive moisture (over 70% RH) or UV shortens display lifetime. – Ghosting image may appear in temperature conditions of less than 15/59 for normal
tags and -25/ -13 for freezer tags. (If L* >2, we call it ghosting phenomenon) Avoid areas with strong magnetism or subject to magnetism.
Contact between the device and a magnetic object can lead to malfunctions. Do not place the product near heat-producing kitchen appliances like a stove or a microwave or
in the vicinity of highly pressurized containers. External impact to the product, such as from being dropped, can damage the product.

Twisting and bending the product can damage the exterior casing and the internal components. If this product operates abnormally while removing battery or replacing battery, it needs to be
discharged by contacting the battery terminals (+) and (-) in the product. This product uses the 2.4 GHz frequency band for the wireless communication network. Radio
communications can be limited or affected by other applications that share the same frequency band, such as WiFi, Bluetooth, Zigbee, etc. A prior investigation into the radio environment is strongly required for efficient and smooth installation. Frequent communications, updates and screen renewals may reduce battery life time. Low temperature environments may reduce battery life. FIFO (First In First Out)
4.3 Product Cleaning
For Spray Cleaning:
Steps Lightly spray all surfaces and wait a few seconds. Gently wipe clean using a cloth or tissue. Let the labels dry.
Notes:
Use mild, non-alcoholic detergents or glass cleaner. Recommend non-abrasive cloths: Microfiber, Cotton T-shirt, Cotton handkerchief, Cotton tea
towel
For Wet Tissue Cleaning:
Steps Stand or lay down the labels. Wipe using wet tissues. Let the labels dry.

5 Battery Handling Guide
SOLUM ESL Datasheet
5.1 Avoiding hazards in lithium battery handling
1. Do not short circuit (Fig. 1) . Direct connection of plus (+) and minus (-) poles may result in leakage, heat generation, explosion
and/or fire. . Do not store and/or carry batteries with metallic items, such as a necklace.
2. Do not stack and/or jumble batteries (Fig. 2) . Stacked and/or jumbled batteries may cause a short circuit and/or forced discharge from contact
with other batteries. . This may result in leakage, heat generation, explosion and/or fire.
3. Do not make forced discharge batteries (Fig. 3) . On a forced discharge by an external power source, the battery voltage goes to negative and this
causes gas generation in inside of the battery. . This may result in leakage, heat generation, explosion and/or fire.
REV 1.6
15 / 19
SOLUM ESL Datasheet
4. Do not dispose of batteries in fire . Disposal of batteries in fire is extremely dangerous with a risk of explosion and violent flaring.
5. Do not heat batteries . Heating batteries above 100/212°F may damage the resin in crimping, separator and other parts,
potentially causing an electrolyte leak, internal short circuit, fire and/or explosion. 6. Do not solder directly onto batteries
. Direct soldering onto batteries may damage the resin in crimping, separator and other parts, potentially causing an electrolyte leak, internal short circuit, fire and/or explosion. 7. Do not recharge batteries
. Recharging of batteries may result in internal gas generation, causing electrolyte leak, battery swelling, fire and explosion. 8. Do not disassemble batteries
. Disassembly of batteries may generate gas that may irritate your throat. . Lithium may also react with moisture to generate heat and fire. 9. Do not deform batteries . Applying extreme pressure to batteries may cause deformation of the crimping and internal short circuit, causing electrolyte leak, battery swelling, fire and explosion. 10. Do not mix different type batteries . For some applications, mixing different types of batteries or new and old batteries, can cause an over discharge due to differences in voltage and discharge capacities. . This may lead to the risk of swelling and/or explosion. 11. Do not insert batteries with opposite polarity . For some applications, battery insertion with opposite polarity (reverse insertion of plus and minus) may result in leakage, heat generation, explosion and/or fire. Please ensure the above precautions are strictly observed by related divisions including production, warehouse, product technology, sales, quality, customer stores, S/I companies, part-time workers, and external service companies.

SOLUM ESL Datasheet 5.2 Proper Storing and Disposing of Lithium Batteries
To minimize risk of fire and explosion of batteries, be sure to follow the instructions below.
Proper use of battery tray is outlined below.
With batteries properly placed into each tray slot stack the trays in the same orientation use an empty tray on the top stack tape the stack together to avoid falling apart.
Follow local regulations for proper battery disposal guideline. REV 1.6
