Press and hold the Lamp, PTT, and Power buttons simultaneously. The radio will power up, perform a self-test (about a second), and display "* SET ". The radio is now ready for field programming. Use the channel selector to choose between programming categories: " SET ", " PROG ", and " MRCH *". In the SET category, press the A key to view the first setting.
