APPENDIX A – Command Summary

This appendix lists all commands organized in the respective functional groups. Parameters that are
part of the radio configuration are identified by having an entry under the “Factory Configuration”
heading. When entering a command, if a parameter that is part of the radio configuration is omitted,
the value for that parameter is not modified.

For commands that are not part of the radio configuration, if a parameter is omitted, the value for that
parameter defaults to the value indicated in bold.
