FIELD SECURE MODE vs. FULL PROGRAMMING MODE

The initial operating condition of a new Citation 20 is called the FULL PROGRAMMING MODE.

In this state, all available functions are accessible and operational to the user, including synthesizer

programming and memory clearing. The Citation 20 is equipped with a second operating

condition called the FIELD SECURE MODE. Field Secure Mode eliminates some functions and

adds protection to the memory. Field Secure adds the following features to the unit:

1.) WRITE PROTECTED

a.) Frequencies that are preprogramming into the unit can not be changed.

b.) New frequencies can not be added.

c.) Names that are preprogrammed can not be changed.

d.) The overall memory of the Citation 20 can not be cleared.

2,) HIDES FREQUENCY

a.) LCD only displays NUMERIC CHANNEL NUMBER and ALPHA/NUMERIC

CHANNEL NAME. The Frequency is eliminated - thus preventing field agents from seeing

actual operating frequency numbers.

b.) Disables the NAME and FREQ buttons on the keypad.

TO PLACE THE UNIT IN FIELD SECURE MODE:

a.) With the unit in Full Programming Mode, turn the Citation 20 OFF. Use the small FSM

tool provided and insert it into the female RCA LINE jack found on the panel. Inside this

jack is a switch. Using the tool, lightly press on the switch, then extract the tool. When the

switch is engaged, the Citation 20 will be in FIELD SECURE MODE. (When the switch is

dis-engaged, the unit is in FULL PROGRAMMING MODE.)

b.) Turn the POWER switch ON.

c.) Observe display - see that the numeric frequency information has been deleted.

d.) The Citation will remain in Field Secure Mode, regardless of power conditions, until

switched to revert back to Full Programming Mode.
