General Radio Operation
 
After a fully-charged battery and an antenna have been connected to the 
radio, operation may begin. If necessary, refer to page 2 to insure a complete 
understanding of the radio’s controls and indicators. Also, for your 
convenience, the “Additional Information” section (starting on page 67) 
contains a glossary, alert tone and status indicator tables, helpful tips, and 
an index.
