Front External Filter Set Assembly
Note:
Both External Filters’ sets should be assembled on the AirHarmony-4400 prior to
installing on the pole/wall mount. Airspan recommends doing the assembly on a steady
secure surface.
1.
Turn the unit over in preparation for the Front External Filters’ set assembly and lie the
AirHarmony-4400 down on a flat surface so as to facilitate assembly of the front external
filters’ set (either Low, High or Full Band).
2.
Place part of the polyethylene packing foam under the unit so as to protect the
AirHarmony from getting any scratches.
