Section 1
Features
This manual is applicable to the Viking Portable 600 radios, software 6.16.x or later. The 
availability of many of the following features is controlled by the model of your radio, 
factory coding of your radio, installed options, firmware version, and field programming.
Note
As of January 2013, the FCC has mandated all UHF/VHF radios shall not allow 
wideband (25 kHz) mode. Federal frequencies are not under FCC jurisdiction; therefore, 
Federal customers can continue to order wideband in VHF and UHF.  This mandate does 
not affect 800 MHz and can continue to have wideband after January 1, 2013. This option 
shall prevent UHF/VHF radios bought after January 1, 2013 from operating in wideband 
mode.
