1 General Description
This S-Tag product is a part of Solu-M S-Label (Electronic Shelf Label) system as well as S-Label Gateway
(S-Gate), Remote controller (S-RC). S-Label system make up a system that electronically displays price
and other product information on S-Tags, which has been traditionally printed or written on paper in
places like retail markets.
S-Tag receives product price/information updates from S-Gate and updates or changes its display of price
and other information.
S-Tag is the product based on IEEE standard 802.15.4 for low power wireless communication
applications. S-Tag consists of RF transceiver, RF circuitry and 8051-compatible MCU offering IEEE
802.15.4 based network protocol and MAC protocol and other peripheral devices.

6 Cautions for Treatment
Provisions should be made to protect against any damage to the product caused by improper handling.
It is highly recommended that the product should be installed within 3 months from the date of arrival in
the logistics hub. Recommended storage condition is in -20 ~ 60 Celsius degree, 35-70% RH environment.
This RF device operates on the 2.4GHz frequency band and can produce radio interference. The device,
therefore, may not be used for applications where safety of human lives is concerned.
6.1 Usage Environment
Take extra cautions 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
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 damaged.
Use the product in temperatures ranging from 0 to +40 . Parts and circuits may be damaged if
used or stored under temperature extremes.
The display panel needs extra care when handling.
-
Do not apply any impacts on outside since e-Paper display is fragile.
-
Continuous exposure to excessive moisture (over 70% RH) or UV makes display lifetime
shortened.
-
Ghosting image may be appeared in temperature conditions of less than 15 Celsius degree.
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 or battery
casing can be separated.
Twisting and bending the product can damage the exterior casing and the internal components.
If this product operates abnormally in eliminating battery vinyl or replacing battery, you should
discharge it by contacting battery terminal (+) and (-).
This product uses 2.4GHz frequency band for wireless communication network. Radio
communications can be limited or affected by other applications which share same frequency band,
such as Wi-Fi, Bluetooth, ZigBee, etc.
Frequent communications, updates and screen renewals may reduce battery life time.
6.3 Battery Replacement
6.3.1 Audience
Authorized persons with the following knowledge are allowed to replace the battery.
Battery
Electronic assemblies like circuit board
Compliance of the instruction
Note : If not authorized person, it will not give any warranty.
