Warnings and Cautions
Human Exposure to Radio Frequencies
The AirStar 1900/1200 5G Sub-6 gHz should be operated from a minimum safe distance of 20 cm (7.87
in.) during normal operation.
Radio Interference
The AirStar 1900/1200 5G Sub-6 generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment on and off, the technician is encouraged to try to correct
the interference by performing one or more of the following measures:
Re-orientate or relocate the unit
Increase separation between the units and/or End Devices
Connect the equipment to a circuit different from that to which the power source is connected

4AirStar 1900/1200 5G Sub-6 Installation
AirStar 1900/1200 5G Sub-6 supports Ceiling (conventional and suspended) and Wall mounting.
4.1 Ceiling Mount
The following defines the AirStar 1900/1200 ceiling-mount assembly procedure for conventional
ceiling or suspended ceilings.

Prior to assembly, in any mounting scenario, determine where the unit it to be installed.
4.1.1 Conventional Ceiling Assembly
The following are instructions for assembly to a conventional ceiling.
1. Select the required location where the AirStar 1900/1200 unit is to be installed, on the ceiling
opposite a window.
2. Position the Ceiling adaptor bracket on the ceiling. Be sure to position the Ceiling adaptor so the
unit will be opposite a window.
3. Mark the screw positions carefully through the holes in the Ceiling adaptor bracket onto the
ceiling.
4. After drilling holes and inserting approved ceiling anchors (plugs) fasten the Ceiling adaptor
bracket to the ceiling with screws and washers (not included).

Screws and washers (x4) and any necessary hardware are not supplied by Airspan and are
the responsibility of the installer. Use appropriate ceiling hardware according to field
conditions. The holes in the Ceiling adaptor are 5/16 (8mm).
