USING THE MFJ 223 TURN ON THE MFJ 223 BY DEPRESSING THE ROTARY ENCODER FOR
ABOUT 3 SECONDS.  AFTER A SERIES OF BEEPS, A START UP DISPLAY WILL LET YOU
SELECT A HELP MENU, THE SYSTEM MENU, OR SINGLE OR SWEPT MENUS ALL FROM SOFT
KEYS.  THE HELP MENU PERMITS YOU TO SELECT A VARIETY OF TOPICS AND REVIEW
THE MFJ 223 SPECIFICATIONS.  THE SYSTEM MENU PERMITS SETTING A START UP
MESSAGE I USED MY CALL SIGN, ENABLES OR DISABLES THE AUTO OFF FEATURE, AND
DISPLAYS THE MFJ 223 SOFTWARE VERSION AND BATTERY VOLTAGE.  I FOUND THE
WELL WRITTEN 19 PAGE PRINTED MANUAL EASIER TO USE THAN THE ONSCREEN MENUS.
I FOUND MOST FUNCTIONS TO BE VERY INTUITIVE.  FURTHER, AS YOU CHANGE
FUNCTIONS, SOFT KEY LABELING CHANGES AS WELL AND HELPS GUIDE YOU THROUGH
THE SETTINGS.  THE SINGLE FREQUENCY DISPLAY FIGURE 3 WILL NORMALLY BE USED
WHEN CHECKING OR ADJUSTING AN ANTENNA.  SET THE DESIRED FREQUENCY BY
PUSHING THE ROTARY ENCODER TO SELECT THE TUNING INCREMENTS, AND THEN TURN
THE ENCODER TO SELECT THE DESIRED FREQUENCY.  PRESSING THE RUN/STOP SOFT
KEY STARTS A CONTINUOUS READING OF THE ANTENNA PARAMETERS.  THE ACTUAL
MEASUREMENTS OF SWR, Z IMPEDANCE, R RESISTANCE, AND X REACTANCE ARE
DISPLAYED AT THE BOTTOM OF THE SCREEN.  THE BAR GRAPHS MAKE IT EASY TO MAKE
ANTENNA ADJUSTMENTS AS YOU CAN ADJUST THE ANTENNA WHILE WATCHING THEM
CHANGE DYNAMICALLY.  FINALLY, YOULL NOTICE THE S ANTENNA BAR GRAPH.  THIS
