2. Overview
SOLUM Newton Core Plus 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), and Server and is
used to electronically display key information such as price and product information, that are
traditionally printed or written on paper in environments like supermarkets, warehouses, and
factories. Offered at an exceptionally competitive price, Newton Core Plus 4-Color (BWRY) ESLs
encompass essential features while incorporating a range of core functionalities that meet modern
demands.
SOLUM’s Newton Core Plus 4-Color (BWRY) Electronic Shelf Labels (ESLs) are the industry leading
solutions that provide the longest battery life, fastest update speed, built in LEDs, multiple pages
per ESL, and more to take the operation beyond just displaying information on the ESLs.
Newton Core Plus 4-Color (BWRY) Electronic Shelf Labels (ESLs) come in various useful sizes (1.6”,
2.0”, 2.1”, 2.5”, 2.8”, 3.5”, 4.2”, 5.8”, 7.5”) and colors to meet all customer use cases.

WARNING: This equipment may generate or use radio frequency energy. Changes or modifications
to this equipment may cause harmful interference unless the modifications are expressly approved
in the instruction manual. The user could lose the authority to operate this equipment if an
unauthorized change or modification is made.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to

interference in which case the user will be required to correct the interference at his own expense.
IMPORTANT NOTE : FCC RF Radiation Exposure Statement
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment.
This equipment should be installed and operated with a minimum distance of 20 centimeters
between the radiator and your body. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.

surface and become damaged.
- Use the product in temperatures ranges of 0℃~40℃/32℉~104℉(BWRY). 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. (If ΔL* >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 2.4GHz 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 lifetime.
- Low temperature environments may reduce battery life.

6.4. Battery Replacement
Audience
- Authorized personnel with the following knowledge are allowed to replace the battery: Battery
/ Electronic assemblies (e.g. circuit board) / Compliance with the instruction
※ Note: Warranty is voided if battery is replaced by unauthorized personnel. (When batteries
require replacement, please contact the authorized personnel)
Instructions
- Risk of short circuit if battery is incorrectly installed/stored.
- Check that hands are dry before and at all times during the replacement Process.
- Keep batteries away from children and infants.
- Do not heat, charge, bend, drop, short-circuit and/or disassemble battery.
- Do not mix together used and new batteries or different battery types.
※ Note: Battery rarely has minor stain or leak.
Steps
(1) Open the battery cover.
(2) Take out the batteries.
(3) Put in the new batteries.
(4) Check the batteries direction.
(5) Put back in the battery cover.

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 Core Plus 4-Color (BWRY) ESL Datasheet
v0.2-PRE
43 / 44
• 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.
