Button
The Front Panel Accessory Button can be software configured to perform a number of
functions such as tone encoder call, cancel function for tone decoder and alarm clear.
Please refer to the radio configuration menu system for additional setup information.
The exact functionality and available features will also depend upon the firmware
version installed.
2.2.2 Adjustments
The SMX920 has adjustable parameters which are under the control of the Micro
Controller. These comprise of TX power, TX VCO deviation, TX reference oscillator
deviation and TX reference oscillator frequency. All of these are adjusted with the aid
of the built-in radio configuration menu system and all except TX power should only
be adjusted as a part of a full TX VF path alignment procedure.
Following adjustment of a digipot controlled parameter the value must then be saved
to the radio to make the change permanent.
