Editable Tx/Rx Diagnostic Variables

The radio operates according to the values of the diagnostic variables

while in the Diagnostic menu. After exiting the menu (by pressing

CLEAR) the radio operation is no longer affected by the values of the

diagnostic variables.

To modify or change the value of an editable diagnostic variable,

press the MENU key when the desired variable is being displayed.

This puts the radio in the Entry Mode.

Enter the new value directly from

the keypad or by using the Ramp

Up and Ramp Down keys

to increment or decrement the

value by one. The new value is

displayed on the bottom line. The

OPTION button can be used to

backspace for editing.

Pressing the MENU key again

causes the diagnostic variable to

take the new value (if it is in the

valid range).

The following diagnostic menu items can be edited:

The PWR, DEV and SQWT variables from the Diagnostic Menu

can be used to Calibrate Tracking Data. The value displayed for

each of these variables represent temporary equivalent Tracking

Data values. The values in these variables can be changed while

making Power, Deviation, or Squelch measurements which will

assist in finding the desired tracking data values. As stated before

the radio only operates according to these variables while in the

Diagnostic Menu. THE TRACKING DATA FOR THE RADIO

CANNOT BE CHANGED USING THE DIAGNOSTIC RADIO

CODE. Once the desired values are found, the Tracking Data must

be changed using the PC Programmer. Refer to the Tracking Data

section in the appropriate Service Manual.
