This procedure is used to update the flash programming for 
the DMU-2000. 
 

V4.21 or V5.11 version software is ONLY needed when the DMU-2000 is used with the New 
FTdx5000 Transceiver. There is no change from V4.20 or V5.10 when used with the FT-2000/D 
or FT-950 radios. If you already have System File [CF1] V0.08 or V0.09 you only need to install 
the [CF2] V4.21 or V5.11 application file.  

* This is the latest software and is compatible with all three FT-950, FT-2000/D and FTdx5000 series.  

 
Check which version DMU software you have on your unit.  

 

While holding the three buttons [GEN]

[50]

[ENT] turn the radio on. The software version will be 

displayed in the lower right of the VFO-A window (FTdx5000 version will be shown in the Center  
OLED display) for 5 seconds then the radio will start up in normal operation.

Two types of computers are used in the DMU-2000. You must use the correct software for 
your computer.  

 

If you have version 

03xx or 04xx

 you must down load 

V0.08/V4.21

. If you have V0421 you 

have the latest software and do not need to update.  

 

If you have 

05xx

 you must download 

V0.09/5.11

. If you have V0511 you have the latest 

software and do not need to update.  

*You may also check the software level on the DMU boot up screen. 

Turn on the DMU front and rear 

main power to boot the DMU processor.  IF the YAESU boot up screen shows this small Phoenix BIOS 

 logo at the lower right of the screen, you have version 

05xx

 and must download 

V0.09/5.10. 

If 

the Phoenix logo is not shown, you have version 

03xx or 04xx

 you must down load 

V0.08/V4.20.

Ver.0.08 

Ver.4.21

After you confirm the type of software it is very important that you only down load the correct 
version from the Yaesu website.

03xx, 04xx or 

05xx

If you already have software Ver.

or

 it is not necessary to 

update the DMU-2000 again.
