such as CHU, BSCU, DPU, and IRU into one hardware unit. iBS delivers stable signal coverage for a
certain area and ensures smooth and continuous communication. It is suitable for users from public sector
such as police, firemen, as well as commercial users.
Highlights
Small footprint, low power consumption, and excellent mobility.
Fan-less design achieved by high-grade heat conductive materials.
Easy installation, low construction and maintenance cost.
Multi-carrier technology and SDR technology, supports up to eight carriers.

Before performing any operation, read the following precautions and operation instructions carefully to
ward off potential risks.
Local Laws and Regulations
When operating a device, comply with the local safety laws and regulations.
Power Supply
Danger
Direct contact or indirect contact (through moist objects) with the high voltage or mains
electricity may result in fatal danger.
Non-standard and incorrect operations on the high-voltage power supply may result in fire and
electric shock.
Never wear conductive articles such as watches, bracelets or rings during operation.
Do use dedicated tools during high voltage or AC operations.
Take necessary measures to prevent entry of moisture into the equipment operating under a moist
environment.
Make sure the lightning-proof grounding is implemented for the equipment to prevent it from being
damaged by lightning strikes.
Disconnect the equipment from the power supply before installing or uninstalling it.
Check the label on the cable to ensure correct connection.
Make sure that the equipment is well grounded before powering it on.
Disconnect the equipment from the power supply if you find water or other liquids in the equipment.
Make sure the power switch is toggled to the “Off” position before installing the equipment.
Working at Heights
Work performed 2 m (6.56 ft.) above the ground is regarded as work at heights. Work at heights, comply
with related local regulations.
Stop such work in any of the following conditions: adverse weather, wet steel tubes, and other risky
situations.
Set danger signs and prevent unauthorized person from entering the work area.
Avoid stacking scaffolds and other materials, and staying or passing below the aerial work platform.
