Once the desired trim is reached, pressing 

  ENTER 

  will return

to one of the corresponding

   screen.  At this point

one may still go back and do further trimming of the 4.0mA limit
by pressing the 

  ENTER

   key, or pressing the Next key changes

to the next function.

TRIM 20.MA

Trimming of the 20.0mA current limit is done in exactly the same
manner as was described for trimming the 4.0mA point. Similarly the
same precautions apply.  After completing the trim 20.0mA pressing
the Next key brings up the menu option.

If all of the set-up and re-ranging operations have been satisfactorily
completed, then pressing   

ENTER   

will return the transmitter to

the normal operate mode.  Pressing the   

 NEXT   

 key at this point

will return the display to the first screen in the sequence,   

SELECT

INPUT.

Note again, that whenever the transmitter is in the display set-up
mode, if no activation of the keyboard occurs for approximately
2-1/2 minutes, the transmitter returns to the operate mode.  One
can also return to the operate mode at any point in the   

DISPLAY

MODE

       by removing power from the transmitter for about 30

seconds, then reapplying power.
