Currently, the only operating mode that is standard with all models is the conventional
analog mode. Other variables such as frequency range are hardware dependent instead of
software dependent.
Radios in the field may be upgraded with new features. A new feature can be purchased
and a special encrypted code string keyed to the Electronic Serial Number (ESN) of the
radio is then provided by EFJohnson Technologies. This string is in the form of a
computer file which enables the feature, and is downloaded to the radio. With the new
option file, the user will also receive a new model number label to be placed on the radio
and a new "Model Number tag".
