10.4.74.6 RadioFreqKey
Determines the frequency hopping sequence of the transceiver. There are fifteen choices
available (0-14) which represent fifteen unique pseudo-random hop patterns. This setting allows
you to minimize RF interference with other FreeWave transceivers operating in the same RF area.
The Frequency Key setting should be the same for all radios in the entire network. The exception
to this is if the RadioFreqRepeat setting is used. If this is used, the Repeater Frequency Key would
be different from the Master radio, and downstream radios intended to connect to the Repeater
would have the same Frequency Key setting as the Repeater.

10.4.74.7 RadioFreqRepeat
This must be set when you want a Repeater to use a Frequency Key other than that of the Master.
This is a setting that is only used by Repeaters. The conditions where this is useful is when there
are parallel Repeaters in a network, and you want to force communications through a particular
Repeater. When this setting is used, the Repeater will receive on the Frequency Key of the
upstream Master (or Repeater), and transmit on its Frequency Key setting (which typically is set to
a different value than the Masters). The default setting of Use Master Frequency Key (box
unused) causes the Repeater to transmit on the Masters Frequency Key.
When this setting is not used the Frequency Key setting should match that of the Master or of
the Repeater acting as the Master for that transceiver.

10.4.74.8 RadioFreqZone
Divides the available band into smaller bands of 7 or 8 channels. A value of 1 enables the band.
l Frequency Zone 1: 902.2464 to 903.8592 MHz
l Frequency Zone 2: 904.0896 to 905.4720 MHz
