4.4.Antenna Connection

You must connect a suitable antenna to the RF antenna connection. This antenna is used for both transmitting and receiving over-the-air messages.

Caution: Do not operate the radio modem without an antenna.

4.5.LEDs

Table 1 interprets the two LEDs on the NL6000.

LED	Color	Meaning
Tx/Rx	Red	Transmitting
	Green	Receiving a signal on the active channel.
	None	Not receiving or transmitting
Pwr	Amber Blinking	Powered on
	None	Powered off

Table 1: NL6000 LEDs

Note: If the Rx LED is continuously green, this means an open squelch or interference problem exists that will inhibit transmissions.

4.6.Operation

It is the responsibility of the user to obtain the proper FCC license to operate this product on the desired channel of operation.
