not lit.	They must be identical for association to occur—Also,
	verify that the system has a unique Network Name.
	b. Remote not yet associated with an Access Point with
	the same Network Name.
	Check the “Status” of the unit’s process of associating
	with the Access Point. Use the Menu System.
	c. Poor Antenna System—Check the antenna, feedline
	and connectors. Reflected power should be less than
	10% of the forward power reading (SWR 2:1 or lower).
	d. Wrong Frequency Mode parameters where units need
	to be time synchronized. Frequency Mode parameters
	are channel, bandwidth and pattern offset.
	e. Wrong encryption settings—The Encryption Enable
	and Encryption Phrase must match on the AP and
	Remote.
	f. Wrong device authentication settings—Verify settings
	match on AP and Remote.
