adapter. Refer to the Power Adapter Specification appendix for more information.
2.2.3 The RESET Button
Hold this button in for about ten seconds (or until the Link LED turns red) to reboot and
restore your ZyAIR to factory default values.

access points. Refer to the Antenna Selection and Positioning Recommendations appendix for
more information.
The following table shows the ZyAIR’s coverage (in meters) using the included antennas. The

coverage area. For better performance, mount the ZyAIR in a high position free of
obstructions.
