TECHNICAL NOTES

 

Radio Compatibility:

  Midian has taken the utmost care to ensure the option board integrates into the radio with 

minimal impact to the features of the radio.  However, some features may not be available in the radio when an 
option board is used.  If a feature is not available, please contact Midian to see if the feature can be added.
