2. Overview
SOLUM Newton Pro Freezer 4-Color (BWRY) Electronic Shelf Labels (ESLs) are components to a
total SOLUM’s ESL System. The SOLUM’s ESL System consists of the ESLs, Gateway(s), Server, and
optional accessories (such as the Newton Pro Remote Controller) and is used to electronically
displays key information such as price and Product information, that are traditionally printed or
written on paper in environments like supermarkets, warehouses, and factories.
SOLUM’s Newton Pro Freezer 4-Color (BWRY) ESLs are the industry leading solutions that Provide
the longest battery life, fastest update speed, built in LEDs, built in button IP68 rating for various
environments, multiple pages per ESL, and more to take the operation beyond just displaying
information on the ESLs.
Newton Pro Freezer 4-Color (BWRY) ESLs come in various sizes and colors to meet all customer
use cases. They are battery powered for ease of deployment and wirelessly receive updates from
SOLUM Gateway for.
3. Specification
This section details the specifications of each ESL by size. ESLs are identified by the diagonal

6. Product Handling Precautions
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 0℃ ~ 40℃ (32℉ ~ 104℉) @45~70% RH environment and should be
installed within 90 days of receipt.
6.1. 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.
6.2. Storage and Use
- The product is shipped in sleep mode (displaying a white screen) and can be activated by
pressing the button, using an NFC remote control, or via the 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 -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 -25℃ / -13℉ for
freezer tags. (If ΔL* >2, we call it ghosting phenomenon)
Newton Pro Freezer 4-Color (BWRY) ESL Datasheet
v0.1.0-PRE
32 / 38
- 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 2.4GHz 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 Wi-Fi, 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)

7. Battery Handling Guide
7.1. 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.
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
Newton Pro Freezer 4-Color (BWRY) ESL Datasheet
v0.1.0-PRE
36 / 38
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.
