during normal repeater operation in order to save current.
2.2.1.2

This setting is used to allow the installation of an encryption module
2.2.1.3
Allow Emergency Transmissions
This option is not currently used.
2.2.1.4

Allow Radio Check
This option is not currently used. In future repeaters, this option will allow a dispatcher to query

Enable Status
This option is not currently used. When the option is enabled it will allow the transmitter to
transmit predetermined Status messages ("low battery", "intruder alert", for example). The Status
messages will not take precedence over user traffic.

Frequency Band
The transmitter’s frequency band is set here. The available options are 136 – 174 MHz and 406 –
470 MHz. The band from 803 – 870 MHz will become available in future models.
