3.4 System Configuration
The System Configuration function displays the software version, database
information, and serial number. This information is helpful when contacting
customer support. It also allows setting the COM spacing, display brightness
and contrast, and to update databases.
3.4.1 COM Spacing
COM spacing may be selected between 8.33 kHz and 25 kHz to allow for
regional requirements.
NOTE: When switching
from 8.33 kHz to 25 kHz mode, any 8.33 kHz-specific
user frequencies will be deleted from the user frequency list. This only
affects the user frequencies within the 8.33 kHz spectrum.
