 Important Notice Regarding Disclosure Restrictions

This information is authorized for distribution only to individuals who
are members of the U.S. Military Affiliate Radio System, Civil Air
Patrol, or other government services specifically permitted by the FCC

1. Remove the two screws from the top cover, and the two screws from
the top rear area of the rear panel, so as to allow the top cover/heat
sink to be slid slightly toward the rear. The objective is to be able
to see into the CNTL-1 Unit, which is the inside part of the front
panel (not the detachable sub-panel).

2. Locate test points TP3001 and TP3002 on the CNTL Unit. They are
located near the top edge of the board, in the center from left to
right. With the transceiver still turned off, connect a jumper
(alligator clip is ok) between these 2 test points.

3. Hold in the following 4 buttons: [PROC], [ATT], [IPO], and [NB].
While holding them in, turn the transceiver on. Release the buttons.

4. The display will indicate OFF. Turn the VFO dial slowly until the
display reads ON.

5. Press the [PROC] button to write the new instructions to EEPROM.

6. Remove the jumper across the test points.

7. Replace the case screws. Mod is now complete.
