2. Whenever must be a qualified technician to setup and maintenance.
3. If you use a shelf (optional accessory), please set aside at least 10 centimeter
distance at the top and the left、 right of the main equipment.
4. Electronic equipment is easy to receive electromagnetic wave, please avoid the
installation of this product in its vicinity, doing so may interfere with radio equipment.
5. Especially the radio equipment should be placed far from the product. Without
prompting, the equipment can radiate radio frequency signals to interfere with radio
equipment, but the RF signal strength is less than the maximum safe limits; radio
equipment should be placed outside of the instrument radiation range or consult an
experienced radio engineer. Basic Function

1.1 Product Brief
DB308 wireless base station is a new active RFID fixed base station for realizing
bidirectional communication between tag and the host system. The station is
century-cn company for electronic shelf label system (ESLs) protocol developed
products. At the same time, the protocol can be extended to other active RFID
industry application.
1.2 Instructions
DB308 wireless base stations operate in the ISM band, and can read ESL label
made by century-cn company. Its maximum reading distance is 30-50 meter ( open
areas).
Base station through a simple IP address settings, you can access the system
from the network data server and through a wireless transmitter sent to the electronic
tag, then receive electronic price tag state information from the wireless receiver
module receives, by the network to the server. The base station actually played the
role of data transfer, the entire process without human intervention.

1.3 Installation Types
According to the specific application environment, DB308 wireless base station
have two installation types: desktop and wall mounting.
Base station installation position mainly depends on its installation type.
According to the installation type, choose reasonable installation position. In general,
base station installation location should be safe and convenient for operation.
In addition, the antenna installation is mainly concerned with the minimum
safety distance.
1.4 Caution Items
AC power supply: 100V-240V/360mA. Please carefully check voltage range
before you use!
Checking base station and antenna installation position and direction,
whether generate signal interference when the base station exchange
information with electronic label.
When this product work (radiation microwave power), the distance between
commissioning personnel with the antenna should be at least 30 centimeter
which can meet the requirements of FCC in the United States for human
exposure to the maximum permissible radio frequency radiation terms! This
instruction is used to guide the installation and commissioning.
Any radio transmitting equipment， including this equipment, it is possible to
interfere to medical equipment without the appropritate protection. If there
are problems in this respect, please to consult with the medical equipment
manufacturer. The work of the equipment may cause interference to other
electronic devices!
