| 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 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. Hold in the following 4 buttons: [PROC], [ATT], [IPO], and [NB]. While holding them in, turn the transceiver on. Release the buttons. The display will indicate OFF. Turn the VFO dial slowly until the display reads ON. Press the [PROC] button to write the new instructions to EEPROM. Remove the jumper across the test points. Replace the case screws. Mod is now complete. ródło: http://www.radiomods.co.nz/yaesu/yaesuft900.html |
